The CNC machining process can be summarized into the following key steps:
1. Programming and code generation: Programmers use specific programming languages (such as G code or M code) to create CNC programs based on design drawings and technical specifications. These programs describe in detail how the machine tool should move and operate to achieve the desired machining results.
2. Program verification and proofreading: Before or after inputting the program into the CNC system, the operator will conduct detailed proofreading to ensure the correctness of the program. The calibration process includes checking key data such as coordinate values, tool compensation, and cutting parameters, as well as the logic and integrity of the program.
3. Tool and material preparation: Select the appropriate tool according to CNC machining needs, and check its accuracy and sharpness. Prepare materials required for processing and ensure their quality and size meet processing requirements.
4. Workpiece clamping and positioning: Accurately clamp the material to be processed (workpiece) on the machine tool to ensure its stability during CNC machining. Through positioning operations, the precise position and direction of the workpiece on the machine tool is determined to ensure machining accuracy.
5. CNC machining execution: Under the control of the program, the machine tool begins to automatically perform cutting processing. During the machining process, the operator needs to monitor the cutting situation and adjust the cutting parameters as needed.
6. Inspection after completion of processing: After completion of processing, conduct a comprehensive inspection of the processed parts, including size, shape, surface quality, etc. Ensure that the processed parts comply with the design drawings and technical requirements, and perform subsequent processing or adjustments if necessary.
Through such a process, CNC machining can achieve high-precision, high-efficiency automated production and is widely used in various manufacturing fields.
