What is CNC Machining?

It’s no secret that the work done within a machine shop has changed significantly over the past few years. The world of manufacturing used to be dominated by assembly lines where workers would perform the same tasks over and over again to rapidly produce high-quality products. As the technology in the manufacturing industry has progressed, so too has the world of manufacturing. Now, a large amount of manufacturing is performed by something called CNC machining. CNC machining and CNC manufacturing represent the next generation of manufacturing. It is important for everyone to familiarize themselves with this industry. Those who are best able to adapt to these changes in the world of manufacturing will be best positioned to remain competitive in the next generation.

An Overview of CNC Machining

For those who might not know, CNC machining is the name given to a manufacturing process that is dominated by advanced computer programming. In this process, a high-precision computer program controls the movements of the various tools and machines within a factory. In this fashion, computers are able to control the complex movements of various machines with extreme precision. Examples of machines that can be controlled through CNC machinery include routers, lathes, mills, and more. With the help of CNC programming, 3D cuts can be performed quickly and accurately with only a single set of prompts. In this fashion, efficiency within a factory can increase dramatically and the output of the manufacturing lines is improved.

What Does CNC Stand For?

CNC stands for “computer numerical control” and has changed how an original equipment manufacturer (OEM) functions. Many compare this process to something called limited numerical control. In contrast to CNC, limited numerical control requires human operators to feed prompts into the system. The human hand is responsible for guiding the machines using tools such as buttons, wheels, and levers. In contrast, a CNC system is more like a set of computer components that are running off of software and consoles. Because computers are able to perform tasks more quickly and accurately than the human hand, CNC is superior to other potential forms of control. For this reason, CNC has risen rapidly in popularity when compared to other forms of manual control or limited control.

How Does CNC Machining Work?

While CNC machining is controlled by complicated computer programs, it is important for everyone to understand the basics. When a CNC system is turned on, the required cuts are entered into a software system as programs. These commands are used to control the corresponding machines. Then, their tools will carry out each of these commands are specified in the computer program. In essence, the machine will function as a robot in a custom machine shop.

The CNC programming is controlled by computer code. This is a numerical function that will ensure that the mechanisms are flawless. Even though errors can occur, these programs are far more accurate than a human operator or manual control. Furthermore, a CNC program can even ask a tool to cut in more than one direction at the same time. This expedites the manufacturing process and can increase the output of a factory.

Many of these CNC machines can retain programs in their memory systems with code that is both written and edited by trained computer programmers. This further increases the efficiency of CNC machines. Finally, CNC machines are not static. They can change and evolve as the circumstances require. New prompts are able to be added to pre-existing programs by simple revisions of the code. This means that CNC machines are able to be adapted to carry out different tasks in a machine shop Denver. Their versatility is unrivaled in the world of manufacturing.

What are Some Types of CNC Machines?

CNC machinery is incredibly versatile and can be applied to a wide variety of machines. As technology has advanced, the mechanisms in these machines have been enhanced with digital computers that have made CNC machining and precision manufacturing possible. Many of the machines in today’s manufacturing world are electronic. This means that CNC machining can be applied to almost all of these devices. There are several common applications of CMC machining which include:

Mills: Mills that run via CNC are able to be run on programs that use both number and letter prompts. These prompts are used to guide the machine across various distances, sometimes in multiple directions at the same time. The code that is used to feed a mill can be tailored to meet that needs of the manufacturers. Mills use a 3D system that functions on the X, Y, and Z axis. Newer mills can add even more axes to increase their efficiency.

Lathes: CNC machining can even be applied to lathes. In the past, lathes were dangerous machines that would lead to horrible accidents. Because lathes can now be controlled by CNC machining, the frequency of injuries due to lathes has dropped. Using CNC technology, circular cuts can be controlled and performed with higher precision and velocity. Because of this, CNC lathes can produce more complex designs than those that could be produced manually. CNC lathes typically are controlled by code that supplies commands on two separate axes. More complex lathes can have 3 axes.

Water Jet Cutters: CNC machining has also been applied to water jet cutters. Water jets are tools that fire a stream of water at high velocity. This water is used to mold hard materials, such as metal and granite, with a high-degree of precision. The water can also be mixed with sand or another solute to shape the target accordingly. CNC machining can be used to control both the speed and direction of the water jet. It can also be used to control the width of the stream. As a result, CNC can be used to mold metal and granite into very specific designs with a high-degree of precision.

Plasma Cutters: CNC machining has also been applied to the world of plasma cutters. This machine uses a white-hot plasma torch to cut pieces of metal and other hard surfaces. The speed and heat necessary to cut metal is incredibly dangerous and produced using compressed air and electrical arcs. The ability to control these devices using CNC machining represents an advancement in the world of safety.

A Wide Variety of Applications with CNC. 

Clearly, CNC machining can be applied to a wide variety of different machines and tasks. Because of CNC machining, these devices can be controlled remotely, increasing safety in the workplace. As technology progresses, CNC machining will become even more important to the future of Denver manufacturing. A CNC machinist can use this type of programming to produce high-quality custom machined parts more quickly than ever before.

What you can Expect from a Career in CNC Machining

At some point in his or her life, everyone has to make a decision as to what they want to be when they grow up. It is not uncommon to continue to ask oneself that question into adulthood. If you’ve ever wondered what it would be like to be a CNC machinist, we are here to lay it out for you.

According to the Bureau of Labor Statistics, there are nearly half a million CNC machinists working in the U.S. That number is expected to stay level through at least 2026. If you’re someone who likes to get your hands dirty, to really get in there and find practical solutions to problems that perplex others, a career as a CNC machinist may be precisely what you’re looking for. If you’d rather be working outside or in a custom machine shop setting than sitting behind a desk, read on. There are a number of things about CNC machining that are likely to appeal to you.

This list represents some of what you can expect to experience as a CNC machinist:

You can expect to learn on the job. Although some CNC machinists are trained at vocational schools, community colleges, technical colleges, or through an apprenticeship program, it is still common for companies to create their own training program for the CNC machinists who will be working for them. That’s because most corporations have a very specific manner of doing things, operational procedures that are not taught in other settings. If you’re someone who gets a thrill out of learning new things, the ability to learn on the job may be of benefit to you.

You can expect to be creative. Anyone who has ever worked in manufacturing, whether they were making baseball bats or secret parts for the Pentagon, knows that things can turn a little frantic when anything goes wrong. Every company is beholden to their customers and must follow strict guidelines and delivery dates. If a part is so much as a thousandth of a centimeter off, it can spell peril for the manufacturer. That’s where you come in. CNC machinists are commonly called upon to get to the root of a problem and come up with a creative way to solve it. If you’re a person who has always enjoyed puzzles, or someone who simply likes a good mystery, this job will offer you plenty of opportunities to think creatively.

You can expect to be part of a team. Teamwork is what it’s all about in this job. People count on you and you count on them to make the most of your workday. Whether operations are running smooth as silk or the sky is falling, and upper management is losing their collective minds, CNC machinists work as a team with every other employee in the company. As a CNC machinist, you can expect people to come to you on a regular basis to ask for your opinion and expertise. In turn, you can ask someone else for help when you need it. For some, it’s the camaraderie that makes the job so enjoyable.

You can expect to be know your value. What you do as a CNC machinist is so foundational to your company’s ability to operate that your absence would present a problem. At some point in their live, most people have had a job in which they felt invisible and unimportant. Nothing could be further from the truth for a CNC machinist. Without them, a business would have no way to control quality, and would be far less likely to come up with new innovations.

You can expect to channel your inner Nikola Tesla. As a CNC machinist, you will be part problem solver and part innovator. What commonly happens in the midst of a manufacturing snafu is that innovations are born that can prevent the problem from arising again. You would be the person expected to come up with innovations that work. Everyone has to start somewhere, but the more you innovate, the more confident you become. CNC machining is a job that allows you to try new things until you come across the one that works. And really, that’s how all great inventors got their start.

You can expect to change.  Not everyone is adaptable, not everyone can shift the way they operate. Because of the nature of their jobs, CNC machinists become supremely adaptable, able to veer from the task in front of them to another when it suddenly becomes a priority. If you aren’t especially adaptable going into the job, you can expect to learn the skill out of necessity.  Adaptability is a trait that carries over into every other area of your life and will stay with you into retirement. In an ever-changing world, the ability to adapt is priceless.

You can expect your skills to be sharpened. Just as a prize fighter become stronger through sparring, your work as a CNC machinist will hone your mental skills. Each day, you will learn something new. Each frustration (and there are frustrations) will bring with it a chance to problem solve. Every level of company hierarchy that you interact with will teach you more about how a corporation works. Through this one job, you will grow intellectually and socially. If, at some point, you find yourself moving to a new company, you will find that you can use what you learned through your first experience as a CNC machinist.

You can expect to be on the cutting edge of technology. Computer Numerical Control (CNC) machines are a blend of digital and physical technologies. In this field it is computers that provide instructions to tools of the trade, such as lathes. For example, it is a CNC machine that allows for the precise shaping of raw materials like plastics or metals. Computers are used in every step of CNC machining, and as a CNC machinist you are the person who is counted upon to understand what’s going on with each step and to troubleshoot in order to keep operations running smoothly. Your computer skills and the desire to learn more are essential for success.

You can expect every day to be different. There is no typical workday for a CNC machinist, primarily because it’s impossible to predict when troubleshooting will be needed or when engineering will change plans midstream. There is very little risk of boredom in this job, a benefit for anyone with a curious mind.

Each person on this planet has a different skill set and different goals that drive them. What most have in common is a desire to spend their workdays doing something that has purpose and offers a sense of fulfillment. If you find that CNC machining sounds like something that would fulfill you, why not take a deeper dive and learn more?

What factors impact the cost of raw material pricing in 2018

Raw material prices are often a hot yet challenging topic for any machine shop in the manufacturing field. Chinese factory closures and the rapidly rising cost of raw materials in the manufacturing industries has proven to be a challenging combination for both producers, suppliers, and consumers.

On a broad level, there are two prime drivers of raw material costs.  One is supplied and demand tightness, like most items, the law of demand and supply governs and controls the prices of raw material. When the supply and demand for a specific raw material gets tight, the costs of raw material significantly increase.

The other contributing factor to the rise of raw materials is the primary feedstock. The primary feedstock for most raw material manufacturing companies is natural gas, oil or metal. Although many CNC manufacturing companies apply the lean principles, raw material prices still pose a challenge especially for Denver manufacturing industries. Apart from primary feedstock and supply tightness, there are other small factors which massively contribute to the cost of raw material pricing.

Cost of labor

The cost of labor is another critical factor. Work is crucial as it influences the actual production rate. With the expansions of free trade agreements and the urgency of supply chain agility, labor cost is a factor to consider in determining your level of production.  Free trade agreements have allowed for massive savings especially when you meet certain local sourcing minimums. Sometimes finding enough domestic labor to qualify for productivity is the hardest part of achieving this savings, making the prices of material go high.

Additionally, chasing low labor impacts the cost of production when it comes to consumer preferences, supply of raw materials and other considerations such as taxes and import and export duties. A shift in the workforce means a shift in raw material pricing.

When Labor Unions strike, a lot of time is wasted and energy lost, less production and transportation significantly affect the pricing of raw materials. Agreements reached by these unions such as salary increment, benefits, and allowances typically affect the pricing. Labor is thus a backbone of any thriving manufacturing company.

 The dollar

A vast majority of raw materials use the dollar as their pricing mechanism for global trade since the US is regarded as the most stable economy worldwide. When the dollar rises, it means that most materials will become more expensive in other currencies.

There is always an inverse relationship between commodity prices and the value of the dollar. Since the dollar strengthened in 2014 to 2016, many commodities have become very expensive, and since then this trend has been witnessed up to now. This is because the dollar tends to be the most stable foreign exchange currency.

When it comes to international trade for raw materials, the dollar seems to be the ideal means of exchange. Another reason for the enormous influence of the dollar is that most raw materials such as oil and gas trade all over the world.

Climate change

Raw materials are needed every day in the daily activities of a factory or industry to push production. Even with the current technology today a lot of raw materials cannot be recycled or reused. This has a tremendous fundamental effect on the availability of raw materials.  However, climate change influences the ease of transportation of these materials to the required destination.  Natural disasters such as the Hurricane Harvey, floods and snow significantly affect transport.

When a place is affected by climate, it is difficult to get materials to their required destination and thus the little that is there means increasing the prices. It is often believed where there is lack of enough supply; the prices automatically go high.

Manufacturing is made difficult in this situation, and the cost of productivity goes high which eventually leads to increased pricing of raw materials. Climate greatly affects the efficiency of labor.

Raw materials prices back in 2017

Raw materials have seen severe price inflation in 2017 due to a variety of factors such as the strong number of markets. The overall price increased between 1 to 4 percent in sales. This significant increase was channeled by competition, high demand and various new markets in the manufacturing industries. As witnessed in this first half of the year, the prices are expected to go higher or remain constant.

Transportation

Every manufacturing industry requires efficient as well as cheap means of transport for both raw materials from the from the factory to the manufacturing industry and finished products from the original equipment manufacturer to the market.

The location of the machine shop should be strategic to ease transportation and for cheaper and adequate transport facilities at a more reasonable rate. If the industry is located at a place where transport would be difficult, the only alternative would be to hike the prices of the raw materials to balance the two rates.

The location of the manufacturing industry.

The location of the industry plays a significant role in the prices of raw materials. If the factory is located at a place where the supply of power, transport, and cost of labor is either unavailable or too expensive, the prices of raw materials in that particular area would most likely be high. Every industry requires fuel to run the machines. Alternative means of power such as hydroelectric, geothermal or coal may significantly affect the prices of raw material. Additionally, the closer you are to the market the easier it is to transport and yield any reasonable profit.

Supply and demand

The demand and supply are the key top drivers when discussing the cost of raw materials.  It is a fundamental economic principle–the more an item is on demanded in any market, the costlier it becomes. If you are producing a product that requires diamond, your product will most likely cost less to manufacture. However, if many people are looking for the diamond, then the material will cost you a dime.

Unpredictable market

The world is a complicated place where things can change any time. Economic or political instability cause speculations which widely affects currency evaluation or other countries failure to contribute or invest in that particular country. Such actions can affect the pricing of raw materials, labor, and taxes.

Machine Shop 101: Top 7 Secrets To Choose Right

Selecting a CNC Machine Shop can be a daunting task with many options available. Innovative strategies are imperative to guarantee selection of a competent shop providing cutting edge technology. Usually, an Original Equipment Manufacturer has experienced evaluators that determine whether a supplier has the minimum requirements.

The team features Quality, Sourcing, and Machining personnel. Each team member represents particular facets of the business. Some Precision Manufacturing set rigorous requirements when conducting supplier evaluation.

Why choose the best machine shop Denver suppliers? 

Choosing a machine shop supplier determines the success of your company in so many ways. Some of the benefits of choosing the ideal one include:

•    Lower costs
•    Reduced scrap levels
•    Great agility
•    Smoother workflow
•    Improved forecasting
•    Reduced setting times
•    Shortened manufacturing lead times

What is the secret?

1.    Samples of Previous Work

Any shop or manufacturer can claim to make the best equipment for every industry. However, custom machine shops that are proud of their products go a notch higher and allows you to inspect their prototypes. Also, they let customers and business owners see all parts and equipment manufactured in their shop.

When customers see examples of previous work, they get a visual representation of their attention to details and craftsmanship delivered to every piece. They get to verify the quality of the end product even when the supplier is working with huge runs of 2-dimensional parts under pressure of tight deadlines.

The ideal CNC machine shop should offer samples on demand and have a command in discussions about their industries of specialization. A knowledgeable and experienced machine shop gives customers great confidence in the quality of their machines. Previous samples confirm that a supplier has honed their skills working with a plethora of materials commonly used in a particular industry.

Don’t you think high end machine shops should be able to deliver precise cuts needed to fit into customer’s specifications?

2.    Enables Project Flexibility

As you choose a custom machine shop that is conversant with crafting ideal parts for your industry, also focus on how flexible they are with particular jobs. The search for a perfect choice should not make you jump from one shop to another. Sometimes, in-house limitations relating to the types of equipment their CNC machinist can work with on their availability and your project.

The best Denver Manufacturing machine shop has in-house skilled machinists, equipment, and necessary experience to get most projects completed as quickly as possible without undermining quality. Ideal manufacturers should also be flexible in offering different size runs ranging from small prototype machining to big scale productions using assortment of materials.

3.    Incessant Improvement

Leading Custom Machine Shops always pay great attention to continuous improvement. Progressive improvements of materials, parts, and equipment produced increases value offered to customers. Some strategies used to measure improvement process include Lean, Six Sigma, Kaizen, and other techniques. Evidence of such quality improvement measuring processes ought to be readily available to customers with proven results.

4.    Offers Excellent Communication Methods

Communicating specifications for prototypes, materials, and parts in any precision machine shop should always be continuous. Alterations can arise at any time. Whenever communication between machine shops and manufactures goes limbo, doubts kick in. Dissatisfaction extends to potential clients through reviews and recommendations.

A quality machine shop focuses on these four customer communication aspects:

•    Allows customers to use their preferred communication channel that suits their operation.
•    Takes time to explain technical capabilities of various machine parts to clients.
•    Offers a contact person who is readily available to answer questions and implement alterations quickly to minimize material waste and time loss.
•    Asks relevant questions concerning customer’s project and how to enhance their job to get value for money and improve their experience.

5.    Implements Quality Control Measures

Quality is paramount for every customer irrespective of parts or equipment ordered. Therefore, every Precision Manufacturing company should create control measures that eliminate production errors in all steps of a manufacturing process. If a shop lacks documented quality control measures, it’s advisable to seek services elsewhere.

A professional Denver Manufacturing shop will be ready to talk about quality certifications such as IS0 9001 and AS9100 standards. They have extensive documentation about the equipment used to determine specification accuracy, for example, coordinate measuring machines. They elaborate what control standards are set for every part, machine, and equipment whenever rejection rate starts to rise.

The best Custom Machine Shop informs their customers about their failure rates and measures taken to reduce this rate to manageable levels.

6.    Equipment and Technology Advances Investment

A CNC shop is just as good as their machinists, staff and equipment produced. It is advisable to research on the types of software and equipment currently used to make the required prototypes and parts. Moreover, ask the shop management about other materials and equipment available in their shop.

Research on all equipment used in the production run phase, for instance, CNC Machining, Wire EDM, and Manual Machining. That information is essential since some stages in the manufacturing process may require hands-on approach for tooling prototypes. The shop should be well equipped with various software capabilities and can modify model designs upon request.

Additionally, CNC Machinists should be well qualified to handle onsite equipment and software efficiently. Their extensive knowledge of all equipment necessary for the production process and how well they use quality measuring equipment should be certified at proficient levels. Therefore, technicians should never hamper any of your bottom lines.

7.    Interact with Previous Customers

After reviewing an Original Equipment Manufacturer capabilities, communicate with previous customers. It is advisable to check reviews given by previous customers online about the shop. Questions that you may ask previous customers include:

•    What customer service got provided?

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.

5S sketch notes on blackboard

How to Implement 5s in the Manufacturing Workplace

The efficiency and the safety of a manufacturing organization are vital for improved productivity, quality production, and profitability. The 5S is a methodology aimed at optimizing the productivity and reducing waste at the factory. It makes use of visual cues and an orderly workplace to achieve consistent results. The 5S is implemented by small teams working together to achieve a higher goal of efficiency. It can be performed in any company that does manufacturing in the USA.

Steps in 5S implementation

1. Sort

The first S deals with getting unwanted obstacles out of the way to enhance speed in the production activities. All unneeded items should be kept away and the right people allowed to do the job at hand. In essence, the production workplace should only have items needed for the current operations in their bare form.

Why is it important to sort?

With enough space, time and efforts can be managed effectively as everything is in its place. In addition, it removes any annoyances and hindrances in the workflow management and lowers incidences of injury where there are moving parts in the production process.

2. Set in Order

The setting order involves arranging items such that they are in the area that they would be used. Each item is labeled for the ease of identifying it at the workplace.

Why is it important?

Setting things in order eliminates several kinds of waste that include;

· Waste of human energy as workers look for items across the facility

· Downtime as production activities await the delivery of the said items

· Difficulty in inventory management as some of the items cannot be traced.

US manufacturing school also teach the importance of putting everything in order as it lowers the chances that a wrong raw material may be used in producing a particular item.

3. Shine

Keeping the workplaces clean enhances efficiency and work morale. Clean machines and tools also work efficiently and do not break down now and then. The workplace and tools used daily should be cleaned each end of the day so that everything is set for the next work day. This applies to hand tools and CNC machining equipment at the workplace.

Why is it important?

· Clean machines produce items with fewer defects

· Puddles of dirt and oil are more likely to cause slipping injuries

· If machines do not receive regular maintenance, they tend to break down more often

4. Standardize

The above-said procedures should be maintained each day. The management of the workplace should standardize the processes so that the conditions do not deteriorate at any point. Similarly, the quality of the products should be maintained by such technology as CNC automation. CNC manufacturing ensures mechanical engineering products are cut to precision every time and products are of the same quality all through.

5. Sustain

The improvements on the procedures should be efficient in the long term. Inspections and audits help determine the effectiveness of any improvement in the production environment. US manufacturing schools teach on quality control especially in mechanical engineering and other production industries. If any improvement does not improve the quality of the product, lower the cost of production or make the work easier, it is not worth implementing.

There is high competition among competing firms in US manufacturing industry. One way a company can lead the pack is by cutting down the waste and maintaining the product standards. In addition to the procedures taught in mechanical engineering schools production managers should enhance optimal productivity by making the workplace efficient, clean and inviting.

5 Lean Manufacturing Principles Every Machinist Should Know

Lean Manufacturing principles are the way to improve manufacturing processes and can be applied to any production process. Every machinist should know these lean manufacturing principles in order to increase efficiency and help reduce costs. With the right lean manufacturing principles, US manufacturing can compete on an international level. There are five principles to incorporate: value, value stream, flow, pull and perfection.

Value

The value should be established early on in the CNC manufacturing process. In determining the value, machinists should look at the needs of the customer for the product. Other things to consider are the timeline, price point and if the customer’s expectations are going to be met.

Value Stream

After value has been determined, there needs to be an established process that takes the materials to the final product, known as value stream. Value stream is mapping out the steps it takes to complete the whole process. Every step needs be identified no matter what department it is in, whether it’s design, production administration, delivery or customer service. Once every step is determined, it’s necessary to go through the steps in order to find ones that don’t create any value and are wasteful. This process can be referred to as re-engineering, and helps better understand the whole organization. It’s important to identify inefficient inventory control, defects or bottlenecks in the process in order to make the system more lean.

In this step, determining everything of nonvalue is very important. It’s necessary to learn the difference between value and waste, and vendors may need to be consolidated. Purchasing supplies and components from one source may eliminate waste, since communicating with multiple people can use up time and money.

Flow

Once the waste has been eliminated from the process through value stream, the next step is to determine the flow of the remaining steps to continue to eliminate any interruptions, bottlenecks or delays. The steps need to flow smoothly. Sometimes it’s needed to look at all departments so they become cross-functional. This can lead to increases in productivity and efficiency, sometimes showing more than 50% improvement.

Pull

The idea of pull is to have the product ready for the consumer at any time, because the steps to make the product have become efficient and that product can be pulled when needed. This saves money for the manufacturing process because products don’t have to be stockpiled and there isn’t inventory just sitting there where people have to manage it.

Perfection

Lean is not just a one-time thing and, in order to achieve perfection and perfect value, the first four principles need to be looked at often and incorporated into the company culture. All employees should be involved in the process. Even though many of the processes are within manufacturing, other departments can still be involved. It may be necessary to repeat value steam and flow to create maximum efficiency.

When implemented correctly, lean principles will help improve efficiency and provide other values, such as increased workplace safety. Lean principles not only can be applied to manufacturing, but also different departments. By thinking outside the box, lean can be used to reduce fatigue in the manufacturing process, which can reduce injury potential. Not only does the company benefit from lean principles, but customers benefit as well.

Improving CNC Machine Shop Efficiency and Productivity

As manufacturing continues to evolve, CNC machinists find themselves in stressful situations since the skills gap is diminishing with time. It has become very difficult to find experienced CNC manufacturing machinists in this industry. The level of competition is up which requires high CNC automation of machine tools to provide stiff competition to other CNC machine providers.

The high demand for quality parts means that mechanical engineering and milling processes must put more emphasis on increased productivity and manufacturing. Today, modern valuable CNC machining tools have made it possible for most shops to modernize their operations. To remain competitive, CNC machinists must find viable ways of increasing their output and maintain reliable, quality and exceptional customer care services.

Time is an important aspect in CNC manufacturing and each machine shop owner wish to make their shops more productive and efficient. Here are three main tips for improving your CNC machine shop efficiency and productivity.

Prolonging the Life of the Tool

Consider having a high-pressure coolant system or increase the concentration of the existing one. It is advisable to examine your tool holder and the inserts from time to time to enhance its lifespan. This simple process helps you to prevent any disastrous failures. You should also record the number of materials that are being removed. Mechanical engineering schools put a lot of emphasis on avoiding extreme contact time with the new materials.

During this process, it’s advisable to go for harder insert grades of your choice which will service you for long. To maintain your tool holder for a long time, some specific coatings like aluminum oxide will help you to reduce the cycle while increasing the lifespan of your tool, feed rates and cutting speeds. Alternatively, you may consider investing in a cryogenic machine.

Improve the Organization

Lack of proper organization may lead to loss of money and significant manpower. There is need to maintain a properly arranged workplace for your business especially if it’s a machine tool. You have to organize things and put them in place when you are done with your work.

You should make sure you invest in quality shadow boards, and tool draws such as those used at US manufacturing schools. You should also improve the labeling system of your arrangements to prevent confusions. Cleanliness of your equipment and shop floor should be maintained since it’s beneficial to your health and business.

Equipment Management System

It is profitable to keep your tool cost as low as possible and invest in US manufacturing tool management system while setting your time down. A good and reliable tool management system will help you to manage and track your inventory. This will enable you to reduce the cost of overstocking or understocking of the tool supply.

The manufacturing in USA enables you to find useful software that will help you control performance, tool usage and procurement in your CNC machine shop. The software also provides crucial purchase notifications to help you avoid costly downtimes. You need to understand that your production quantity isn’t the only factor that drives business growth. You need to thoroughly evaluate the kind of services you are providing to your clients and streamline your overall business processes.

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.

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.
