What is CNC machining of parts

The control system issues instructions to make the tool perform various movements that meet the requirements, and the shape and size of the workpiece are expressed in numbers and letters in terms of technical requirements and processing requirements. It generally refers to the process of processing parts on CNC machine tools.

A CNC machine tool is a machine tool controlled by a computer. The computer used to control the machine tool, whether it is a special computer or a general-purpose computer, is collectively called a CNC system. The movement and auxiliary actions of the CNC machine tool are controlled by the instructions issued by the CNC system. The instructions of the numerical control system are compiled by the programmer according to the material of the workpiece, the processing requirements, the characteristics of the machine tool, and the instruction format (numerical control language or symbols) prescribed by the system. The numerical control system sends out operation or termination information to the servo device and other functional components according to the program instructions to control various movements of the machine tool. When the part processing program ends, the machine tool will automatically stop. For any kind of numerical control machine tool, the numerical control machine tool cannot work without inputting program instructions in its numerical control system. The controlled action of the machine tool roughly includes the start and stop of the machine tool; the start and stop of the spindle, the conversion of the rotation direction and the speed; the direction, speed, and mode of the feed movement; the selection of tools, the compensation of length and radius; the replacement of tools, and cooling The opening and closing of the liquid.
