Understanding the Basics of CNC Machining: Materials, Tools, and Processes

The most successful in the parts production industry today is CNC machining, and it brings several advantages over the traditional production processes. The advantages include efficiency, safety, accuracy, and more. So, here is an overview of the basics of CNC machining that you must know.

What is CNC Machining?

CNC machining is the process of using solid materials with high-speed cutting bits to carve out a product that does not require any joints. The high-speed cutting bits are controlled with a computer where the users may upload the 3D design of their product, and the material through which the part is carved out is usually held firmly at the base. The computer provides specific coded instructions according to the G-code of design, and that's how drills can achieve a high accuracy of 0.01 micrometers when producing products or their parts.

What materials are used for this process

One of the biggest advantages of going with CNC machining is that it supports working with a range of materials, including metals, plastics, wood, composites, ceramics, etc. So, here is a list of the most common materials used for CNC machining:

• Aluminum
• Steel
• Titanium
• Plastics
• Wood
• Foams
• Fiberglass
• Carbonnier, etc.

What tools are used for this process

A CNC machine uses multiple tools and bits during different parts of the machining process. Some of those include:

• End mills
• Face mills
• Drill bits
• Boring bars
• Reamers
• Lathe tools
• Thread mills, etc.

The step-by-step CNC machining process

The process of working with a CNC machine may seem very complex, but it is very simple compared to traditional manufacturing techniques. So, here is a step-by-step overview of the CNC machining process:

1. This process starts with the initial design of the product. It is usually created as a 3D design in a CAD file that is supported by the CNC machining computer.
2. The CAD file is processed using computer-aided manufacturing software that generates the G-code from the CAD design. This G-code is given to the computer that will be controlling the machines.
3. Now, the material for making that part is fixed firmly to the base, that is, either a table of that machine or a chuck. During this phase, all the required tools and bits are loaded into the CNC machine that will be used during the production process.
4. Now, the CNC machine is instructed to start working on the material, and it will automatically select the tools for working on the material and machine out the product from the solid material.
5. After the machine process is complete, the part is inspected to ensure that it meets certain requirements.
6. Post-processing is the last step where the product gets surface finishing, like sanding, painting, etc.

With these 6 steps you have the final product ready for usage.
