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.

Industry concept: Lean Manufacturing on computer keyboard background

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.

CNC Automation Trends

Machining Technology Trends 2018

2018 is already off to an exciting start when it comes to CNC manufacturing and CNC automation. The US economy is improving, jobs and growth are projecting higher for US manufacturing for the coming years, and new technologies are emerging in CNC automation. Here’s a look at some of the top machining technology trends for the coming year (and beyond).

1. Demand for Machine-Tooled Products Is Increasing
Consumer confidence is on the rise and the US economy is ramping up after a slowdown of many years. This means the demand for machine-tooled products will be on the rise as well. New changes to US tax laws and trade policies are increasing the demand for domestic manufacturing. This will also make it easier for new CNC manufacturing startups to get off the ground, because they can be more competitive with established overseas machining operations.

2. CNC Growth Projections Are High
CNC manufacturing is projected to grow in demand across nearly every sector this year. Take a look at the estimated 2018 growth in CNC industries from an analysis by Gardner Business International:

Medical Devices & Instruments: 5.1 percent increase
Surgical Instruments: 3.1 percent increase
Automotive Manufacturing: 2 percent increase
Aerospace Parts & Engines: 3 percent increase

3. Demand for CNC Manufacturing Jobs Projecting Upward
This is actually a “good news and bad news” trend for the moment, with the bad news coming first. The CNC manufacturing sector overall was not ready for the increased demand for precision machined products. In the short term, the skilled labor gap is going to get worse than it already is. Mechanical engineering schools don’t have a lot of new slots opening up, while the industry needs skilled and trained workers for CNC automation and machining. Bottom line: There aren’t enough workers to keep up with demand in the short term. However, that is good news in the long run. The job outlook for the CNC Manufacturing sector looks better and better through 2018 and beyond.

4. More Touchscreen Controls
Companies that make precision CNC machining equipment are rapidly implementing more touchscreen controls. The controls make it easier and faster to pre-program machinery and tools for 3D cutting tasks. Program navigation, editing, creation and verification are all made easier by implement touchscreen controls with manual keypads. CAD/CAM programming and USB communication with interfaces allow even more options, versatility and ease-of-use on the machining shop floor. The implementation of touchscreen controls has added more speed to the CNC machining process, which is great when manufacturers want to quickly push more product out the door.

5. Robotics & Regulations
As the CNC manufacturing sector continues to expand, human engineers are increasingly working in proximity to robots. State and federal government will eventually step in with new regulations related to functional safety. While it hasn’t happened yet (beyond regulations that are already in place under OSHA), the industry is holding its breath for when that day comes. When it does happen, it will likely have a ripple across the domestic CNC manufacturing industry which will increase product costs for consumers.

Lean Manufacturing Waste

7 Wastes of Lean Manufacturing

One of the effective ways of increasing the profitability of any enterprise is through waste elimination. Processes can either add more value or massive wastes to the production of goods and services. The seven wastes of lean manufacturing came from Japan where there were referred to as “Muda.” The first step towards eliminating waste is understanding what waste is and the specific places where it exists in your processes. The wastes found in various manufacturing environments tend to be similar. Here are the seven wastes in lean manufacturing.

1. Overproduction

Overproduction refers to the process of manufacturing specific items before they are needed in the market. Overproduction is expensive since it hinders the uninterrupted flow of material and degrades the quality of products produced. Overproduction in industrial manufacturing is usually referred to as “Just-In-Case” manufacturing. This type of manufacturing will lead to significant storage costs, excessive lead times, and make it almost impossible to notice defects. The solution to this waste is stopping the production tap. You should only manufacture what can be shipped or sold immediately.

2. Transportation

The waste of transportation usually refers to the movement of items between different processes. This will involve the use of a forklift truck or similar equipment to move products around the factory. Transportation is a waste occurring as a result of overproduction. Excessive movement of products around the factory will cause harm and can also lead to deterioration in the quality of the products. The equipment used to move the products around the factory lead to another production cost that adds no customer value.

3. Over Processing

Over processing is extra work that adds no significant value to the consumer or business. Over processing is a waste that takes the form of adding unnecessary features to a product that the customer doesn’t use but raises the cost of production. A good example of over processing would be maintaining paint finish more tightly than required or building a product that will last for five years when you know that the customer will replace it after two or three years.

4. Excess Motion

The waste of excess motion is related to wasted movement and is evident in all cases of walking, stretching, lifting, bending, and reaching. Some of these issues are also related to safety and health which is becoming a major concern in today’s world. Technically, jobs that require excessive movement need to be analyzed and re-engineered for significant improvement with the participation of the industrial workers.

5. Excessive Inventory

Excess inventory is a waste representing cash that is tied up in the form of material which is technically difficult to turn into liquid cash quickly. Inventory eats up much storage at the manufacturing plant since it has to be managed and stored. It can also become obsolete leading to more waste. The quality of any inventory can undergo deterioration over time especially perishable goods such as rubber seals or food.

6. Waiting

The manufacturing waste of waiting hours occur whenever products aren’t moving or being processed. Waiting is perhaps the most common lean manufacturing waste of the seven. It is lost time due to poor flow of production process. Equipment breakdowns, part shortages, and bottlenecks can also lead to waiting wastes. Waiting can also frustrate the workers leading to reduced morale. The Goldratt’s theory of constraints states that every hour lost in a typical bottleneck is like an hour lost to the entire factory output which is impossible to recover.

7. Defects

Defects have a direct and substantial impact on the quality of products manufactured. Defects will lead to rescheduling, re-inspecting, and loss of capacity. The overall cost of defects is always a substantial percentage of the entire manufacturing cost. This waste can be reduced through continuous process improvement and employee involvement in the production process.

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.

The Role Of CNC Automation In Modern Manufacturing

No business can survive without adopting the most advanced technologies, and in manufacturing, there are few devices more important than CNC machines. CNC, or Computer Numerical Control, manufacturing involves operating lathes, mills, drills, and other devices from a single computer. Manufacturers program the computer with precise instructions for the products they want to make; the machines can then manufacture those products without any additional input. CNC devices dramatically improve efficiency and cost-effectiveness, and have thus become a mainstay of modern manufacturing.

The CNC revolution is only beginning, and with each year manufacturers develop new, more effective ways to use this technology.

Advantages Of CNC Automation

CNC automation has a wide range of benefits for the manufacturing process, including:

• Consistency

    1. – Other than needing occasional downtime for maintenance and repair, CNC machines can perform the same job exactly the same way 24 hours a day, every day of the year.

• Volume

    1. – A CNC machine can produce the same product over and over again, thousands of times. All of the products will be identical to each other, eliminating the chance of mistakes after the programming stage.

• Intricacy

    1. – A CNC machine can follow any programmed instruction down to the most intimate detail. This allows manufacturers to create products with much more precise designs than manual devices or older forms of automation could achieve.

• Efficiency

    1. – The precision of CNC machines also means that they can use every material presented as efficiently as possible, dramatically reducing waste and thus the cost of production.

• Safety

    1. – CNC machines represent complete manufacturing automation; the operator never has to touch the materials being used. As such, it is ideal for manufacturing tasks that involve extreme temperatures, toxic or corrosive materials, or other factors that would place human operators at risk.

• Speed

    1. – CNC devices combine multiple steps in the modern manufacturing process, dramatically reducing the amount of time it takes to finish production.

• Simplicity

    1. – Whereas other forms of manufacturing automation require skilled operators, a CNC machine requires a relatively low level of skill to use. Under ordinary conditions, a single operator can also supervise multiple machines at the same time, leading to lower labor costs.

 

    Compared to these advantages, the only significant disadvantage of CNC automation is the high up-front cost. By improving efficiency, reducing waste, and preventing mistakes, CNC machines quickly make up for their initial prices, providing long-term savings for manufacturers in a wide range of industries.

What Comes Next? The Future Of CNC Automation

The CNC revolution is only beginning, and with each year manufacturers develop new, more effective ways to use this technology. At present, experts are focused on ways to integrate CNC machines with with the robots used to move and pack finished goods. Doing so will streamline the manufacturing process, reducing waste and increasing simplicity. A single control panel may one day be enough to direct an entire manufacturing operation.

Another key development is the advent of the CNC 3D printer, which has made this type of manufacturing available to smaller businesses and even individuals. As these devices fall in price and grow in complexity, CNC manufacturing will become increasingly personalized and decentralized.
