[0002] A CNC machine tool is an automated machine tool equipped with a program control system. This control system logically processes programs specified by control codes or other symbolic instructions, decodes them, and represents them as coded numbers, which are then input into the CNC device via an information carrier. After processing, the CNC device issues various control signals to control the machine's movements. The parts are first fixed using a positioning device according to the shape and size specified in the drawing, and then the parts are automatically processed according to the instructions.
