[0002] Numerical control machine tools, also known as CNC machine tools, are automated machine tools equipped with a program control system that can logically process programs specified by control codes or other symbolic instructions, decode them, and represent them in coded numbers, which are input into the numerical control device through information carriers. After calculation and processing, the numerical control device sends various control signals to control the movement of the machine tool, and automatically processes parts according to the shape and size required by the drawing. During the process of cutting and processing the workpiece, a CNC cutting and processing positioning device is required for positioning, clamping and fixing;
