CNC Machining Process: A Step-by-Step Guide
1. Design parts
The first step in custom CNC machining involves creating a detailed design of the component. Engineers use CAD (computer-aided design) software to generate digital models that contain all specifications, tolerances and material requirements.
2. Prepare CNC program
Once the design is complete, it is converted into a CNC program using CAM (computer-aided manufacturing) software. The software converts the design into a language the CNC controller understands, including specific instructions for tools, speeds and feeds.
3. Material selection and setup
Choosing the right material is critical to the performance of your part. Once the material is selected, it is ready for machining. This may involve cutting the raw material to size and securing it in the machine’s workpiece holding system, such as a vise or clamp.
4. Machining operations
CNC machines perform programmed operations, which may include processes such as milling, turning, or drilling. Modern CNC machines are often equipped with multiple axes (3- to 5-axis machines), allowing complex shapes to be machined in a single setup.
5. Quality control
Quality control measures are implemented throughout the entire processing process. This often involves the use of precision measurement tools to ensure that machined parts meet predetermined tolerances and specifications.
6. Finishing process
After parts are machined, additional finishing processes such as polishing, anodizing or coating can be performed to enhance performance characteristics or surface finish. These processes are critical for applications in industries such as aerospace and medical, where surface integrity is critical.
