CNC machining is a popular way to make things, and it can be used to make things of different sizes. People choose CNC industrial machining for many reasons, such as cutting costs and making things that are better quality. Because of this, the number of items that can be made with this method can change.
To make it easier for you to understand, this post will show you how CNC machining works in a certain way. It’s important to show CNC production in a unique way because it’s often a delicate process. Because of this, this piece will go into more depth about the different terms and ways of machining. Additionally, you will learn what you need to know before hiring a business for CNC machining services.
Why Should You Use CNC for Production Machining?
CNC (Computer Numerical Control) machining is a subtractive manufacturing process that uses computer-controlled tools to machine material into precise parts according to a specified design. During the process, a computer program instructs the machine to systematically remove material, ensuring that the final product precisely matches the original CAD design.
These CNC machining methods increase productivity by providing complex parts that are precisely measured and meet the highest quality standards. In addition, CNC machining dramatically reduces production time compared to traditional manufacturing techniques. Once machines are programmed, they can run continuously around the clock, reducing downtime and increasing productivity.
CNC machining is usually categorized into two main methods: low-volume production and high-volume production. Here are the differences between the two types of production.
CNC Machining for Small-volume
Low-volume CNC machining services, where a limited number of parts are manufactured using computer numerical control (CNC) technology, specialize in batches of 50 to 1,000 parts.
Some people now like a small lot of CNC machining because it usually has these benefits：
- It fills the gap between the prototype and the initial projected production run
- It reduces costs
- Increased access to fledgling markets
- Ideal for processing products with short life cycles
CNC Machining for Large-volume
High-volume CNC machining meets the needs of a wide range of industries that produce precision parts in large quantities, efficiently transforming raw materials into consistent, high-quality finished products.
It is capable of producing more than 1,000 parts quickly, reducing costs and labor requirements while minimizing the safety hazards associated with manual processes.
Advantages of the CNC Machining Process
More work getting done and less waste. When using CNC production machining, you can get more work done with fewer people. This is because computers are more accurate and efficient, which increases the productivity of your business. For instance, work that is done all around and by machines makes everything run more smoothly. Better software is also used, so there is less waste of products.
Less work to do. It’s not hard to do CNC machining, whether it’s for a small or large amount of parts. This means that work costs less money. It doesn’t mean there’s no work, though. There are still jobs that need skilled workers to oversee every step of the production process.
Increase profits. CNC machining is a production process that does not require much supervision. Because CNC machining cuts down on labor needs and costs, things made with it are very cheap. On the other hand, high-volume CNC machining can further reduce costs. Therefore it can increase the profit of the company.
Things to Know About Hiring CNC Machining Services
You should know a few things before you hire a CNC machining service like CNC machining to do work for you. These three things will help you get ready for the jobs you’ll need to do in CNC manufacturing.
Standard Manufacturing Process
It’s not hard to understand how CNC machining works at its most basic level. We’ve broken down the process of CNC production into four steps below to help you understand them better.
Making the CAD model
This is the first step: making the CAD file. Most computer-aided design (CAD) files are saved in 2D or 3D, and CAD software can read them. There is a lot of technical information you can show about every part of the finished object with CAD software. Don’t forget that your project is a big part of the design answer. This is discussed in more detail in the Materials Required for CNC Machining section.
Convert CAD Files to CNC Files
As soon as the CAD file is ready, put it into the CNC program. The software has functions that look at the CAD file to get the computer code that the machining process needs to run.
There are two main types of code that CNC machine programs use. One is G-code, which stands for “geometry code” and is used for making shapes. In other words, you can set the machine to move in different ways, at different times, along different paths, and so on. The other code is M, and it controls the CNC machine.
Setting Up the CNC Machine
Part of setting up the CNC machine is getting it ready to work. Setting up will be different if you are doing low-volume or high-volume cutting. There are lathes, mills, grinders, and other tools used in the machining process in this machining. A good business that does CNC machining should also have an experienced engineer in charge of the process.
Executable Operation
Machining can start once you are sure that everything is set up and on time. A previously set program tells the CNC machine what to do and how to do it to get the right results.
Improved Design and Materials
Most of the time, getting the best design means finding out how to use the materials in the best way. Read these tips to get the most out of the qualities of the things you use to make parts.
Make the Design Simpler.
During the planning stage, optimizing a part’s CAD file can help avoid extra machining steps. Optimization can also fix other issues and cut down on the time needed to run the process. The best thing to do is get rid of any extra parts that are there.
Selecting the Right Wall Thickness
You might feel pressure from things that are made with CNC tools. It is important to pick the right wall width for the part because of this. Because it is too thin, the wall will be too weak and likely to break. It is also important that the wall is not too thick, since that can make the tool hang off, bend, or break.
Skip the Small, Hard-to-read Text and Features
If your project requires you to do markup and writing, it’s best to skip the small markup and text. This is due to the increased cost of completing more complex operations. Instead, please enlarge the text or markings.
Use Standard Hole Sizes
You should use standard hole sizes when you need to make holes. This makes sure that everything is done right and saves time.
Quantity and Transit Time
When using a CNC machine to make something, quantity and transit time are also very important. Most CNC machining businesses today can handle jobs of all sizes. On the other hand, wait times rely on how complicated the software is, how up-to-date the machine is, and how well the software can run.
Suppose someone wants to get the best quality and number in a reasonable amount of time. The machining method needs to be understood, along with the people who can do it.
