CNC numerical control processing Traditional mechanical processing is performed by manual operation of ordinary machine tools, shaking by hand during processing Mechanical tools cut metal and measure the accuracy of products with calipers and other tools. Modern industry has already used computer digitally controlled machine tools for operations. CNC machine tools can automatically process any products and parts directly according to the program prepared by technicians in advance

Parts processed on CNC machine tools are generally divided into processes according to the principle of process concentration. The methods of division are as follows:

(1) Divided by the tool used

Take the process completed by the same tool as one Process, this division method is suitable for situations where there are many workpiece surfaces to be processed. Machining centers often use this method to complete.

(2) Divided by the number of workpiece installations

The process that can be completed in one clamping of the parts is regarded as a process. This method is suitable for parts with few processing contents. Under the premise of ensuring the processing quality of the parts, all processing contents can be completed in one clamping.

(3) Divided by roughing and finishing

The part of the process completed in rough machining is regarded as one process, and the part of process completed in finishing is regarded as another process. This division method is suitable for parts that have strength and hardness requirements, require heat treatment or require high accuracy of parts, need to effectively remove internal stress, and have large deformation after machining, which needs to be divided into rough and fine machining stages.

(4) Divided by processing part

The part of the process that completes the same profile is regarded as a process. For parts with many processing surfaces and more complex, the sequence of CNC machining, heat treatment and auxiliary procedures should be arranged reasonably, and the connection problem between the procedures should be solved.
