The Keys to Successful High Speed Machining in your Machine Shop

Advancements in CNC manufacturing and industry developments in high speed machinery are just two of the factors that are driving a global CNC machines market that is expected to reach $100 Billion by the year 2025, according to a research study. This industry growth is underpinned by CNC technology that provides manufacturers with a reduction in machining errors, lower operating costs for machine shops, and lower labor costs when state-of-the-art factory automation is implemented in US manufacturing sectors across the board.

Taking Advantage of CNC Manufacturing

The key to successful high speed machining in your machine shop is directly tied to your adoption of high speed CNC machines and tooling or partnering with a machine shop Denver that delivers high speed, custom machine shop services to US manufacturers. These companies provide mills, lathes, grinders, ad routers controlled by computer CNC programming to operate at a significantly higher feed rate – and with a minimum of tool breakage.

Expect a cleaner cut with high-speed machines that operate at lower heat per piece due to the efficient manner in which metal chips are evacuated. The result is tooling that remains cooler with less vibration and a reduction in other machining forces when compared to conventional machine shop operations.

These inherent traits of CNC manufacturing will also provide 3 other major benefits to US manufacturing production – repeatability, precision, and range of materials:

  • Improved Repeatability: CNC programming and machines can reproduce a shop outcome that is unchanged for multiple pieces running at high speeds. Even more important than accuracy, repeatability means errors can be traced and compensated for, to reduce scrap and gain higher precision for intricate geometry machining.
  • Component Precision: When 3D Computer Aided Design (CAD) software is used in conjunction with CNC machines, expect components that are manufactured to exact and extremely precise specifications. Complex shapes and fine or thin parts which at one time required a Master machinist and hours of labor are now easily manufactured without error.
  • Greater Range of Materials: Aside from common manufacturing metals, CNC machining is used to produce components and products from a wide range of materials, including steel, aluminum, bronze, gold, and silver. Today, many domestic consumer products manufactured from polymers such as ABS and PTFE are machined using high speed production as well.

4 Keys to Successful High Speed Machining

Staying competitive in an increasingly fast-paced manufacturing arena means achieving better productivity from your  manufacturing automation strategies. And when it comes to high speed machine shops, the following four keys will do more to ensure success than most other factors:

Material Selection Process

Due to the high feed rates of high speed machine (HSM) processing, softer materials don’t fare as well. For the best results, tough or hardened materials provide the best results. When you consider that different materials are processed at vastly different speeds, mostly due to the preservation of the machine’s cutting tool life, the most common metals include hardened steels, stainless steel, tool steel, and titanium, and often mild steel.

CNC machines are high performing and depend upon critical attention to every detail between the cutting tool, the CNC program, and the material being cut, including:

  • spindle rpm
  • spindle power
  • high feed rates
  • tool path rates

Material properties will affect the material removal rate and how much wear and tear is being placed on the cutting tool. Companies can overcome these material selection challenges by partnering with a machine shop Denver that specializes in CNC manufacturing and custom machine shop processes. Here you will find the expertise required to overcome component material specification and cutting tool material challenges and how material will relate to depth of cut, coolant flow rate, and the type of coating for the cutting tool.

Acceptable Workpiece Geometries

While CNC machines are regularly used to process common geometries, when it comes to high speed operations, the tool geometry and tool access to all parts of the working piece are dependent on the geometry of each component. Workpiece geometry with internal or ‘hidden’ cuts will often place a limit on to the maximum depth of an undercut.

Likewise, the stiffness of the workpiece and the tool must be matched to reduce deformation and vibration during machining, otherwise the temperature increase due to cutting forces are too great for high speed applications. Consideration of workpiece geometry also includes maintaining a minimum wall thickness for a successful component that is machined using high speed CNC equipment.

The Right CNC Machinery

If your CNC machines are not rated for high speed operations, then expect broken tooling and lot’s of scrap pieces. There are a wide range of factors that are needed for high speed production to run smoothly – and these factors mut be considered when selecting a CNC machine for your machine shop. From complex mechanical parts to mold & die processes, the right CNC machinery depends on:

  • Part Complexity
  • Machining Operations
  • Operator Training
  • CNC Control System
  • Cost Per Part
  • Available Floor Space

When setting up floor space for high speed machining, operations may need to be rearranged to accommodate material flow from point-to-point for increased productivity. When selecting a machine, worker safety and chip disposal during non-stop machining operations are an integral part of operations planning.

If you are in the process of choosing a CNC machine shop Denver to drive your high speed manufacturing projects, request samples of their previous work and discuss any in-house limitations they may have which can affect how flexible they can be during production.

Partner with a US manufacturing service provider that can run a range of project sizes from big scale productions to small prototype machining with a variety of materials.

Access to Trained CNC Operators

There is no denying that there exists a shortage of skilled CNC operators in America to fulfill the needs of manufacturers for trained and experienced workers to fill new positions in high speed manufacturing. The Golden Age of skilled machinists existed during the Baby Boomer generation – and today that workforce is retiring at a record pace.

The majority of Millennials that have entered the manufacturing industry have looked to supervisory or management positions in lieu of the traditional machine shop occupations that were held by their parents.

For these reasons, companies are finding access to trained CNC operators that are experienced in the nuances of high-speed manufacturing by turning to third party or outsourced, machine shops to meet demanding production schedules.

CNC Manufacturing

How Changing Manufacturing Perceptions Are Shaping the Industry

The manufacturing industry in general, including CNC manufacturing and precision manufacturing, is one that is consistently recognized as one of the most important industries that contributes to economic prosperity. However, the US manufacturing industry is facing a gap. Not only are there not enough skilled workers available, but also there isn’t an interest in pursuing long-term careers in CNC manufacturing. A lot of this has to do with the public perception of the industry.

What Is the Public View of Manufacturing?

Americans value the industry, with 83% believing that manufacturing is important to economic prosperity in the country. Seven out of 10 Americans believe that the country should invest more in the industry. Eight in 10 Americans view manufacturing as an important way to maintain the standard of living in the country. Sixty-four percent believe that the manufacturing industry in the country is high tech. Even with these positive stats, Americans still aren’t choosing careers in CNC manufacturing. One-third would not encourage their children to pursue a career in manufacturing because they believe it doesn’t pay enough, is not a strong career path, and they are worried about the stability and security of the job. While 67% believe these jobs are rewarding and interesting, only half believe that a career in this industry provides good pay when compared to other industries.

Even though Americans aren’t encouraging their children to pursue those jobs and don’t seem to want to have these jobs themselves, they are optimistic about the future of manufacturing jobs and do believe that these perceptions can change and improve. Americans believe that future jobs can have better career prospects because they will require higher levels of expertise, have safer and cleaner environments, and be more innovative and creative. In order to get more people interested in manufacturing jobs, Americans believe there should be more targeted programs, such as apprenticeships and internships, as well as CNC manufacturing degree and certification programs. When Americans become more familiar with the industry, they are twice as likely to encourage their children to pursue a manufacturing career.

Education Matters in the Industry

As Americans are becoming more educated about the industry, their perception is changing. In order to fix some of these perceptions, it’s necessary to increase the pool of qualified candidates to be able to get the right talent to staff the roles that today’s manufacturing companies need. Community colleges, as well as technical schools across the country, are working with government and non-profit agencies, as well as manufacturers, to develop curriculum that will help make sure that students have the in-demand skills that are needed for these roles. These institutions, as well as manufacturers themselves, are better understanding the role that they play in transforming the public perception. Oftentimes in the past, manufacturers would spend money to invest in technology and equipment, but didn’t invest in their existing workforce and in the human capital. Due to this, the industry has fallen behind and is lagging when it comes to adapting to new operations in more technologically advanced environments. Schools have worked with private manufacturers in order to develop programs that will help focus on specific skills employers want, which not only makes it easier for the manufacturers themselves, but also benefits the students who want to make sure they can get a job when they are done with school. An example of this is a worker training program with American Makes. This organization is a leading partner in research for 3D printing and additive manufacturing. The organization is a public-private partnership that works to accelerate and innovate additive manufacturing with the goal to help increase the manufacturing competitiveness in the United States. The curriculum that is offered is skills-based training, and the apprenticeships offer a range of jobs that are in demand with a focus on the 3D workforce.

Improving the US Manufacturing Competitiveness

In order to improve perceptions about the industry, more than three-fourths of Americans agree that there needs to be a more strategic approach to invest and develop the manufacturing base. Seven in ten Americans believe that a strong manufacturing base should be a priority for the nation and there should be tax incentives to encourage it. There needs to be lowered health care costs, reforms in the education system, and a comprehensive energy policy. These are just some of the actions that Americans believe could help bolster the competitiveness of the US manufacturing industry.

What’s Really Happening in the Industry?

The manufacturing industry provides one of the most stable and secure career paths, and the average tenure of workers in manufacturing jobs is the highest among private sector industries. Manufacturing jobs have some of the lowest turnover rates as well. Despite what some think, CNC manufacturing jobs are paying well. According to statistics from the Bureau of Labor and Bureau of Economic Analysis, the average worker earned $81,289, which included benefits and pay, compared to the average worker in other industries only earning $63,830. Health benefits can be a concern with job seekers, and manufacturers have some of the higher percentage of workers who are eligible for health benefits provided by an employer. Skilled workers are needed, especially over the next decade. About 3.5 million manufacturing jobs will be needed, which is due to a combination of the retirement of Baby Boomers and the strengthening economy. By making these statistics more well known and increasing public awareness, it can help dispel false perceptions to help get the news out that the industry is actually doing pretty well. Manufacturing is a big contributor to the US economy. The industry employs about 12 million people and the effect of it ripples throughout the entire nation. For every one dollar that is spent in manufacturing, another $1.81 is added to the economy. For every job that is added in the manufacturing industry, four other jobs are added in the broader economy.

How Trends in the Industry Affect Perceptions

Different technological advances that are entering the industry, such as IoT and robotics, are also changing perceptions that are helping to shape the industry. Despite the new technology and many people thinking that technology is going to replace jobs, there is still a huge demand for jobs that are more skilled and can work alongside the changing technology. While some jobs are lost due to robotics and new technology, these jobs are being replaced with higher skilled jobs, which pay more and offer more stability. The newer jobs for higher skilled workers are exactly the kind of jobs that are needed to counteract the negative perceptions that go along with the industry.

GD&T

GD&T 101: Understanding Fundamentals of GD&T in a Machine Shop

In precision manufacturing, electrical specs are ideal for specifying electrical components appearing on a drawing. Mechanical components require unique spec system that are replicable.

Also, mechanical spec system should be clear, precise and not excessively restrictive. Geometric Dimensioning and Tolerancing (GD&T) is the new phase of precise designs.

What is GD&T?

Geometric dimensioning and tolerancing (GD&T) is the primary international language that aims to offer clarity in most drawing interpretations and specifications. The ideal use of GD&T in CNC manufacturing helps in the elimination of vague drawings. Vague drawings give room for guesswork, controversy, and assumptions in manufacturing and inspection processes.

GD&T is a language of standards and symbols wholly designed and used by top CNC machinist, engineers, and manufacturers worldwide. They use this language to describe products and facilitate communication between entities working together to create products.

Through advanced knowledge on the best practices to create a well-structured GD&T, you can improve communication with your custom machine shop Denver. As a result, everyone in the workplace speaks the same language.

Why is GD&T Important?

GD&T may seem like a complex language. It requires correct interpretation and specification for efficient and effective communication. Improper implementation can cost your company a lot of money. Nonetheless, excellent training offers your employees sufficient comprehension of GD&T and its proper application on a particular job.

Constant measurement and effective communication across engineering processes and disciplines are vital for production of superior products. GD&T helps you achieve this goal. It’s primarily designed to address major challenges facing companies and organizations when describing product geometry.

GD&T symbol language allows for accurate communication of all geometry needs for any related components and assemblies. Designers, engineers, and manufacturers use the ‘language’ to understand detailed engineering drawings in commercial design, automotive, manufacturing, electronics, and aerospace industries.

Moreover, it assists in controlling and specifying forms, location, and orientation of the features. GD& T also characterizes machine shop components and manufactured parts.

GD&T symbols for every dimension on a manufactured part or component are defined in connection to a datum. Datum is a theoretically perfect plane, point, or line on a manufactured component perceived to be the reference point for all dimensional measurements and tolerance calculations.

All datum(s) on every manufactured or designed component is considered as the ‘zero point.’ Calculations get built from the reference point to every other dimension to guarantee consistency of particular parts. Therefore, manufacturing, design, and quality engineers get great manufacturing and measurement clarity. Furthermore, incorporation of a datum dramatically simplifies all specification and design processes.

ISO-certified GD&T languages have successfully replaced complex and long industrial descriptions with simple symbols. The symbols are clearly and unanimously understood by all precision manufacturing personnel required to read and interpret any engineering drawing.

Benefits of GD&T

GD&T offers many benefits to OEM manufacturers. The entire design philosophy implemented in GD&T is similar to that extensively featured in functional dimensioning. Every part gets defined based on how it functions in the end product.

The designer meticulously bases the required tolerance on part function instead of copying it from a previous drawing. This strategy enables the use of maximum tolerance in the production of parts.

When applied appropriately, functional dimensioning, often multiplies the total tolerance on most component dimensions twice or thrice. Dimensioning significantly lessens the overall manufacturing costs.

With the incorporation of accurate coordinate dimensioning, all tolerance zones are not associated or connected to any functional requirements. In case a designer assigns tight tolerances, problems can occur since they are not in any way resolute in the determination of a beneficial and functional tolerance.

So, why use GD& T?

Round tolerance zones

Round tolerance areas permit roughly 57% supplementary tolerance compared to square zones which result in additional functional parts. The manufacturing process gets enhanced in capabilities when more tolerance on the parts. This helps in significant reduction of manufacturing costs.

Bonus Tolerance

Under certain conditions, GD&T creates room for a bonus tolerance in addition to round tolerance. The bonus comes from the use of Maximum Material Condition (MMC) modifier. The MMC modifier increases tolerance in precision manufacturing.

Bonus tolerance is a practical example of a win-win situation for the involved OEM since manufacturing can get further tolerance when holes are bigger than their smallest functional size. On the other hand, clients get a guarantee parts will assemble without a hitch.

Tolerance zone in coordinate tolerancing is always constant with size irrespective of hole conditions. Several functional parts can be scrapped to create a more rigorous condition for CNC manufacturing. Bonus tolerance allows for additional tolerance in production which assists in lowering operational costs.

Reduces Assembly Problems

GD&T inspection process ensures that all parts assemble correctly. Assembly procedures don’t necessarily require a CNC machinist on the assembly line using a hammer and a two-by-four.

Moreover, GD&T inspection process ensures that OEMs can obtain multiple sources or use competitive souring for the same part. The reduction of assembly problems consequently increases your company’s profitability.

Clear Communications for Inspection

GD&T’s datum system enhances clear communications of a single set up feature for inspection. The assessment equipment mainly stimulates datums. The symbol that is universally used in the specification of any datum denotes the part surfaces that meticulously touch the gaging apparatus during inspection.

All datum features get chosen based on part function and assembly requirements. They are in most cases the features that comprehensively mount and precisely locate parts in its specific assembly. The datum(s) reference letters get specified within the statistical and geometric controls. They also symbolize the series in which specific part surfaces majorly contact the gaging equipment.

GD&T supports SPC use

GD&T datum system offers repeatable part dimensions essential for designing a reliable SPC chart. SPC data might comprise of assumptions with implementation of coordinate tolerancing which diminishes the accurateness of data obtained. Profile control use is an ideal example of how GD&T supports SPC.

Profile control helps in the establishment of a mathematically distinct tolerance zone. Moreover, it relates extensively the obtained measurement to datums. Precise tolerance zone description does not exist whenever coordinate tolerancing is used.

Profile control together with datum system enhances the accuracy of the obtained SPC data. Therefore, no unnecessary changes are made in the Original Equipment Manufacturer and Denver Manufacturing processes. It saves time and money for the company.

For original equipment manufacturers to realize the benefits of GD&T, correct utilization is key. When used incorrectly, it can result in costly errors. For example, if a manufacturer uses erroneous drawings to choose machines to use and production rates, it results it incorrect cost estimates. In the long run, manufacturers end up using wrong equipment and producing substandard products. Solution?

Manufacturing Sector

Is US Manufacturing Making a Profit?

Many people view the manufacturing industry in the US as one that is untouched by technological changes. This skepticism has led to some questioning whether the manufacturing industry is making a profit in this era.

Addressing concerns on the decline of the manufacturing industry in the US

The manufacturing industry experienced a major hitch during the recession, with more than 5.8 million workers losing their jobs between the years 2000 and 2010. While the 2007-08 recession played a major role, many attributed this to the automation and the introduction of robotics in the manufacturing industry, some thought that this was a sign of the slow growth of the US economy and that the US was losing its grip to support its population.

According to the IMF, the decline does not necessarily indicate a shift in the industry’s size. Instead, sector inequality is what is bringing about this concern. In a recent IMF report, Bertrand Gruss stated that “the decline in manufacturing need not be a source of concern as long as the policy mix is right.”

Though the industry has gone through dark times in the recent past, data from the US Census Bureau shows that it is making profits, with the first quarter of 2018 having a $154 billion, up from the $117.6 billion that had been realized in the last quarter of 2017.

Manufacturing trends behind the industry’s current profits

Labor automation
The use of CNC manufacturing has played a major role in the success of this industry. While this is no magic wand, it has made manufacturing companies more competitive. Automation of processes and the use of digital machines has led to increased productivity as tasks that were done manually at higher costs, and less accuracy are now automated. This has led to a significant drop in manufacturing jobs, but its benefits far outweighs the challenges. Through an efficient production process manufacturers realize an increased output which ultimately leads to increased profits.

Machine outsourcing and leasing
Automation has not come without its fair share of challenges. These human-capacity-saving machinery in most cases have extremely high upfront costs. However, any company can now walk into an Original Equipment Manufacturer and lease any machine. This, coupled with the many financing options has given the industry a major boost. Finance companies are offering to settle not only the machine’s cost but other soft costs such as its installation and freight.

Rising demand
The US remains to be a lucrative market for manufactured items. This has continued to lure both local and international manufacturers to open companies in the US. The streamlining of global logistics has opened up this industry to the world. Technological innovations have made the moving of products and services faster, cheaper, and easier. As such, manufacturers have increased their visibility to potential clients not only in the US but all over the globe. This has seen the demand soar especially in emerging economies. With the increased demand, manufacturers have doubled their output capacity, which explains their profit story over the last few years.

Further, the rise in global demand has led to US manufacturers seeking international allies. In most instances, the US manufacturer works on the design and the products’ functionality while the international partner manages distribution in the country they are in. This has also enabled the manufacturers to widen their global reach and maximize their revenues.

The rise in industry technologies
Manufacturers can now efficiently source for raw materials or deliver their finished products anywhere in the world. They can now have multiple facilities all over the globe, as opposed to the past where facilities were set up depending on the raw materials’ proximity. Through cloud connectivity, such facilities can sync data which is accessed by each facility in real-time.

Evolution in the precision manufacturing sector has made manufacturers maximize their production output, increase the machine’s running times, and reduce downtimes. Through design and simulation tools, manufacturers can validate the products’ design before the final production. This results in the production of perfect products and reduced design time.

Increased diversification to service provision
The integration of automated systems in the production process has necessitated that there be a constant support for optimal efficiency. Case in point is IBM, which actually sells more services than goods. Many Denver manufacturing shops also offer services that are meant to help companies maintain and upgrade their machines. This has led to diversification and eventual realization of profits.

The future of the manufacturing industry in the US

Concerns on whether the US will be able to recoup its position as a leader in the manufacturing industry continue to be a significant bone of contention. The US population is also waiting to see whether the current administration will deliver its promise, that is, ensure that the low and middle-class workers get their manufacturing jobs back. Besides, everyone wonders what impact increased manufacturing automation have on the workforce in the long run.

All indicators show that the manufacturing industry is experiencing a resurgence, and focus is shifting to policies that will accelerate this growth.  Policies such fewer government regulations and investment in infrastructure geared towards enhancing manufacturing are expected.

While manufacturing jobs are returning to the US, it will be necessary for any machine shop Denver, to employ the same skills that were applicable a few years ago. As a result, we will see more efforts from government agencies and corporates to bridge the skills gap. The curriculum also has to be adjusted and relevant programs introduced to ensure more skilled labor is available.

Also, no CNC machinist is going out of business as technological innovations lead to production efficiency and the production of high-quality products. Undeniably, we can only expect more automated processes. This will further be influenced by the evolution of the Internet of Things. We can expect advancement in M2M applications, 3-D printing, and AI equipment. It is hard to find a custom machine shop that is not making use of such technological innovations for products with multiple customization options and fewer flaws.

The manufacturing industry plays a major role in the US economy. Increase in efficiency due to automation will ultimately lead to increased production, time-saving, reduced downtimes due to the use of smart machines will all lead to higher profit amounts and a healthier economy. While these changes are welcome, they will lead to changes in the workforce and better products.

Education concept: Helpful Tips with optical glass

Tips for Choosing a CNC Machining Partner

While the US machine manufacturing industry continues to grow rapidly, choosing the best strategic partner for your CNC machining can be quite challenging. However, this process should not be that difficult if you have the correct pieces of advice beforehand. Below are some machine shop tips that you might want to put into consideration when sizing up for the best service provider.

#1: The Technology in Use

The power of technology cannot be underestimated in the engineering and manufacturing sector. Therefore, it is an excellent idea to know the type of technology in use in your preferred machine shop. While there are many companies out there relying on standard technology, this could be a constraint when it comes to both design and machining. That is why it is paramount to work with a manufacturer who is fully automated and equipped with all the necessary precision tools and equipment. At Tag Team, we have heavily invested in Computer Numerical Control (CNC) manufacturing that allows us to deliver precise component machining to our customers. Additionally, this revolutionary approach to manufacturing helps us to achieve zero-defects because once your design is fed into the computer; our CNC machines can repeat the production process multiple times. This also helps to lower lead-time.

#2: The Expertise of the Staff

Sometimes you may go with a price that you think is good only to end up with a component that does not conform to your print or assembly. In other cases, your project may be delayed, and the excuse the manufacturer tells you is “your component design is too complex.” Therefore, you need to be vigilant when dealing with machine shops and only work with a company that has a reputation for interpreting designs and prints accurately and delivering projects on time. At Tag Team Manufacturing, we have created a work environment where our machinists make a long-term career. We know very well that expensive equipment and software are worthless if they are not coupled with qualified and experienced staff to deliver quality services and meet the exact customer specifications. In fact, the vast majority of our machinists are US manufacturing schools graduates and can handle all complexities relating to components design and implementation.

#3: Range of Materials and Services

Choosing a manufacturer who offers diverse metal machining services can save you a lot of time and paperwork. Consider a case scenario where you want a design component that has to incorporate several metals or materials. Definitely, it would be much more convenient to outsource to one manufacturer than several of them for a single project. That is why we at Tag Team Manufacturing have CNC machining for a variety of materials including plastic, stainless steel, aluminum, copper, brass, carbon steel, and most alloys. Besides, we have an extensive network of support vendors who provide brazing, plating, heat treatment, painting, and welding among other services.

#4: Relationship Sustainability

For those considering to enter into an Original Equipment Manufacturer (OEM) contract with a CNC machining firm, you might need to evaluate the sustainability of the relationship. First, put into perspective whether the manufacturer has the requisite CNC automation to meet your demand and needs. Second, the machine shop you want to enter into a contract with should protect your business interests and keep the requirements of the end-users in mind. That being said, Tag Team has an excellent reputation for producing components for EOM’s in almost all industries. Our production capacity is about 50, 000 components annually, which means we can meet your demand without compromising on quality. In addition, we protect the interest of our clients, as we do not publicize our relationships with EOM’s who buy components from us.

Precision Machine Shop

Things to Look for When Hiring a Precision Machine Shop

People should look for several items when they are choosing a precision machine shop to make certain that they make the right choice.

Communication Skills
The person in the shop that you are telling about your job or project should have great communication skills. They should be skilled at their job and know what the others in the shop can accomplish. If this person is experienced, they will also have questions for you to help you to describe your job in as much detail as possible. Great communication is the first skill to look for, because if you and the shop manager are not on the same page, your project may not come out as you saw it.

Innovative Technology
A good precision machine shop is only as good as the available technology they use and it is based on the technician’s knowledge to use it. Research what types of equipment are needed to manufacture a prototype of your project. Then ask what types of equipment the machine shop uses such as CNC Machining, Manual Machining and Wire EDM. Also, ask if the process uses more than one type of machining for the run. The machine shop should also be able to have certified technicians to run the software available for the process so they can implement any changes in the design that you may ask for. Shops with the latest technology are forward thinking and will learn and implement new processes to keep up with the rising technology needed.

References and Samples of Work
A great machine shop will have a project book with photos of some of their past work along with the customer’s names and phone number and won’t be afraid to share these things with you. If they don’t give you references or explain past processes, they may be hiding something about their performance from you. The project book should have their most difficult jobs that they completed in it to show how capable the machine shop is in their business.

Flexibility
Machine shops that are proficient in their work will have some sort of process to allow flexibility in the project while it is underway. They should report to you at certain steps of the process to make certain they are on track and be able to change things if it isn’t to your specifications. This helps to get the first prototype correct and sets in place the specifics for a full production run of your products. If they don’t have a schedule set up, you may want to look elsewhere for a precision machine shop that is more compliant.

Quality Control
All machine shops should have a quality control inspector, whether in-house or out of house to ensure that your project meets all of the specifications that it should. They should be willing to talk about their quality certifications such as ISO 9001 and AS9100 standards and share with you what types of equipment they use to ensure the standards are met.

Looking for these items will help you to find a quality precision machine shop that you can use for prototypes, parts and projects of any size to successfully fulfill your wishes and demands.

high-speed machining

High-Speed Machining: What Is It and How Does it Help?

According to the US mechanical engineering schools, high-speed machining can be defined in two different ways. However, the most commonly used definition is based on the relative surface speed between the workplace and the CNC manufacturing tool. This definition is primarily a thermo limit since most of the CNC mechanisms depend on temperature. According to surface speed definition, high-speed CNC machining is favored by metal cutting researchers and toolmakers from US manufacturing department.

Researchers and tool makers define high-speed machining by indicating the range of a transitional region which is yellow, conventional machining region which is green and high-speed region which is red and depend on surface speed. The surface speed is in meters per minute, and its equivalent to v=πdn where n is spindle speed and d is the diameter of the milling work piece.

The second definition which is widely used by mechanical engineering schools is the DN number that is centered on the rotation capability of the loaded spindle bearings. D is the diameter in mm of the larger bearing bore, and N is the spindle speed in rpm.

High-Speed Machining Principles

High-speed machining operates on several principles. Keep in mind that not every type of machining will benefit from HSM, but most applications could from HMS with implementation of CNC automation and assumptions. Below are high-speed machine principles.

How Does High-Speed Machining Help?

Every machining shop desires high productivity and improved machining process. Machinists make complicated metal parts, shapes and need to run complicated programs to help them provide good services to their clients. Machinists use high-speed machining to make their work faster and easier. Here are some benefits of using high-speed machining.

Reduced Energy or Heat Loss

High-speed machining helps in increasing the rate and speed of material cutting which reduces excessive heat loss and transfer. When you reduce heat transfer, turnaround time and transmission are kept low which lowers energy consumption. Traditionally, time was provided for metals to cool down and form a hardened metal but in this case, the coolant is used in metal cooling which reduces heat loss and increases the speed of production since less time is spent on cooling.

Increased Productivity Rate

High-speed machining has driven manufacturers and machining shops to higher rates of productivity. Faster productivity rates mean the machines can produce more parts in a short period. However, the functionality of high-speed machining is often affected by the ability of the cutting materials themselves. Manufacturing in USA prefer the use of faster cutters since their productivity is high.

Even if all cutters are faster, the results produced by cutters of different materials are unique. For instance, diamond, ceramics, HSS, tungsten carbide and cermets cutters all provide different outputs. High-speed cutting tools can take a lot of time and may even lead to stress. The main problem that is associated with high-speed cutting tools is that they don’t manage heat effectively and require a coolant.

Machine Shop

History of Machine Shops

A machine shop is a specialized room, building, or big company where CNC machining and other types of machining are done. The activities that take place in such a shop involve experts/machinists using various machining tools and cutting tools to come up with different parts. People tend to think that a machine shop must be a massive building with complex equipment but this isn’t true.

A typical machine shop can either be a portion of a large factory or simply a small store such as a job shop. The various parts manufactured are usually sold to multiple lines in the US manufacturing industry, car industry, and even the aviation industry. The production of these critical parts typically involves cutting, shaping of the parts, drilling, and finishing.

History of Machine Shops

The history of machine shops can be traced back to the 19th century when the first mechanical engineering schools started to come up in the U.S. The first machine shop appeared around this time. It is also during this time that the industrial revolution was at its peak and there was a high demand for various parts. Before this era, critical parts and tools were mainly produced in local workshops in villages and cities. However, the production was limited to small-scale, and the parts were primarily sold to local CNC manufacturing artisans.

Production of parts in large factories took place on site where every part was produced individually. As time passed by, the plants started to come up with their workshops to deal with the production of the required parts. During those days, the textile was still the dominant raw material.

After the 19th Century

Further developments in mechanical engineering CNC machining took place in Germany, Scotland, and England after the 19th century which led to the development of cheaper and simple techniques for the massive production of steel. This development triggered the rise of second industrial revolution which played a significant role in the electrification of factories, mass production of parts, and also an uprise of more US manufacturing schools.

Machine shops gained popularity around this time as they were commonly referred to locations where complicated mechanical parts are cut to the required size and carefully put together to form complete mechanical units.

However, the rise of the machine shops came along with its fair share of both manufacturing and organizational problems. This triggered the emergence of various theories and publications trying to solve the problems.

One of the earliest publications in the field of mechanical engineering which gained a lot of popularity was a series of books titled; “Modern machines_ Shop economics” that was authored by Horace Lucian.

20th Century

The beginning of 20th century saw an increase in the number of publications relating to machine shops with various authors including Frederick Winslow Taylor and Howard Monroe More funds were directed towards research and invention which led to the invention of the electric motors in late 20th century.

The electric motors took over power supply of the common machine tools from the conventional mechanical belt. This era also ushered in CNC automation and numeric control in the field of manufacturing in the USA. The two aspects production design and primary production became integrated.

American-Made Products

Popular Products Manufactured in the U.S.

Have you ever bought something because it read the label, “Made in the U.S.A.“? We’ve all been there. We all like American-made products and we value what’s constructed in our own country. Although the number is increasing, not a lot of products are made in the U.S. In fact, about 50% of the products we use are made in China. However, America is trying to even the playing field. With our increased knowledge of mechanical engineering and the US manufacturing schools available, more and more products involve manufacturing in the USA.

Furthermore, a new technology has advanced over the years — CNC machining and manufacturing. CNC manufacturing is a manufacturing process where a pre-programmed computer controls tools and machines. This is done through CNC automation, where computers and machines do all the work for us. This has created a mechanical engineering breakthrough leading to more excitement surrounding the United States manufacturing industry. But since China still makes over half of the products we use, what’s manufactured in the United States? See below for a list of the most popular products made on U.S. soil:

-Primary Metal
-Machinery
-Transportation Equipment
-Weber Grills
-Tesla Roadsters
-Harley Davidson Motorcycles
-Whirlpool Appliances
-KitchenAid Mixers
-GE Hot Water Heaters
-Stihl Gas-Powered Equipment

From machinery to kitchen mixers, the United States still makes some of the more important products that we use in our everyday lives. And with CNC manufacturing leading the way in mechanical engineering, machines are working smarter and more effectively. In addition, education for the mechanical industry is getting better year after year. Mechanical engineering schools are popping up everywhere and more people are realizing the importance of these skills.

Increased Productivity and Lower Costs Lead to US Manufacturing

With more and more products being manufactured in the United States, there has to be a reason why our production efforts have increased. One of them is our productivity. American workers have been proven to be more productive in the workplace. They are paid higher than employees are in other countries and the work environments are more enjoyable. With child-labor issues happening in China and other countries, more people choose American-made products for that reason alone. Another cause for increased U.S. manufacturing is shipping costs. Every day, it is getting more expensive to export materials from one country to the next. In order to save on costs and produce high-quality, dependable products, many manufacturing companies are choosing the United States are their hub.

The U.S. Prefers American-Made Products

The average American will choose an American-made products over one that’s produced in another country. Although China leads the pack for most of the products we use, that number is starting to decrease. One reason for the change is CNC manufacturing. As our technology gets more advanced, CNC automation and machining is growing in popularity. From production benefits to saving on costs, CNC manufacturing is here to stay.

ISO 9001

What is ISO and What are the Steps to Becoming ISO Certified?

ISO 9001 originated from the conglomeration of two different organizations namely United Nations Standard Coordinating Committee (UNSCC) and International Federation of the National Standardizing Associations (IFNSA) in 1946 when over 25 nations convened at the Institute of Civil Engineers in central London.

ISO (International Organization for Standardization) creates all the essential documents that provide specific guidelines, requirements, specifications, or characteristics that are used to ensure that materials, processes, products, and services are highly fit for their purpose. The body has published over 22025 International standards which can be purchased from the ISO store. The standards cover all sectors including manufacturing in USA, mechanical engineering schools, and even CNC automation.

The ISO 9001 standards bring real and more measurable benefits in various sectors since the standards underpin the technology most industries rely on and ensures quality is adhered to in every stage of CNC machining and CNC manufacturing. Some of the benefits of being ISO 9001 certified include improved efficiency and cost savings, widened market potential, higher level of client service which leads to higher customer satisfaction, and compliance with procurement tenders.

What Are the Steps to Becoming ISO 9001 Certified?

Obtaining an ISO certification for US manufacturing schools or any other industry player requires a significant investment of time, effort, and money. This is a process that will take some time to complete. Below are the essential steps to be followed while seeking ISO certification.

Select a Credible Certification Body

The journey towards being ISO certified starts with identifying a qualified certification body to help you in the process. Since most of the ISO 9001 standards for mechanical engineering are based on a three-year cycle, most of the certification parties will expect the company to sign up a minimum three-year agreement to be considered. Some of the certification bodies will insist on visiting your company several times a year to assess the progress, but a single visit is usually enough to establish the milestones achieved towards the certification.

Develop a Management System

Developing a Management System is an essential part of achieving ISO certification standards. There is the Quality Management System for ISO 9001 standard and the Environmental Management System for the ISO 14001 standard. The core components of the quality management system include analysis and improvement, provision of resources, processes of management activities, and product realization. Once you’ve developed your management system, you’ll be required to fully implement the system, verify if it’s effective, and register it.

Stage 1 Audit

Once you have the quality management system in place, a thorough audit of company activities is what follows. An auditor evaluates your existing systems and provides a well-analysed report identifying suitable actions that need to be undertaken to meet the specific standard. Stage 1 audit is mainly used as a roadmap to the next phase of auditing, so there is no need to worry if you feel like the company is underprepared.

Stage 2 Audit

Stage 2 audit involves fixing all the problems that were identified in stage 1 audit. Once you’ve implemented in the recommendations put forward in the report of stage one audit, an auditor will come in again to complete stage two audit. The purpose of stage two audit is to determine the effectiveness and efficiency of your management system and to establish whether it meets all the requirement of the ISO 9001 standards that you want. If the system is good and it meets all the requirements, then the company will be recommended for ISO certification.
