5 Lean Manufacturing Principles Every Machinist Should Know

Lean 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 manufacturing and each CNC 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.
