What is the CNC machining process?

Ordinary CNC machining generally refers to precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling, etc.

1. The feed processing route of the CNC lathe moves from the tool point (or the fixed origin of the machine tool) until it returns to this position and completes the processing program, including cutting paths, tool cutting, cutting and other non-cutting empty paths.

2. The feed line of precision machining is basically carried out in accordance with the contour sequence of the parts. Therefore, the focus of determining the tangent is the feed line for rough machining and idle travel.

3. In the process of CNC lathe processing, the following principles must generally be followed, and the accuracy and surface roughness of the processed workpiece can be guaranteed.

4. Shorten the processing route as much as possible, reduce the idle time, improve the processing efficiency, simplify the workload of numerical calculation, and simplify the processing program. For some reusable programs, subroutines should be used.

5. CNC refers to the programming and control of CNC machine tools with NC processing language, generally G code. The NC machining G code language tells the CNC machine tool which Cartesian position coordinates to use for the machining tool, and controls the tool's feed speed, spindle speed, transfer tool, coolant and other functions.
