Precision CNC machining custom according to the pre-prepared processing program, CNC machine tools automatically machining processing parts. Everyone prepares the machining process route, process parameters, tool trajectory, offset, cutting parameters (spindle speed, feed rate, cutback amount, etc.). and roles (tool change, spindle positive rotation, rotation, cutting fluid opening and closing, etc.). According to the command code and program format specified by the CNC machine tool to prepare the processing program table, and then in the control material (such as hard disk, magnetic bubble memory) to record the contents of the program table, the process of generating instructions from the part diagram is called CNC programming. The difference between CNC machine tools and ordinary machine tools is that CNC machine tools automatically process parts according to the program, and ordinary machine tools require manual operation. Therefore, we can process different parts by changing the program that controls the movement of the machine. Therefore, CNC machine tools are especially suitable for processing small batch parts with complex shapes and strong accuracy requirements. As the CNC machine should process the parts according to the program, the programmer should compile the program, input the CNC equipment and command the machine to work. The input of the axis CNC machining program is made by the control medium.
