NC machining of Wuxi parts refers to the machining that the control system sends instructions to make the cutting tool make various movements that meet the requirements, and represent the technical requirements and machining process requirements such as the shape and size of the workpiece in the form of numbers and letters. It generally refers to the process of machining parts on NC machine tools.

CNC machine tool is a machine tool controlled by computer. The computer used to control the machine tool, whether special computer or general computer, is collectively referred to as CNC system. The movement and auxiliary action of NC machine tool are controlled by the instructions issued by NC system. The instructions of the NC system are given by the programmer according to the material and processing requirements of the workpiece The characteristics of the machine tool and the command format specified by the system (numerical control language or symbol). The numerical control system sends 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 machining program of the parts is completed, the machine tool will automatically stop. Any kind of numerical control machine tool cannot work without inputting the program instructions in its numerical control system. The machine tool is affected by The control action roughly includes the start and stop of the machine tool; Start and stop of spindle, change of rotation direction and speed; Direction, speed and mode of feed movement; Tool selection, length and radius compensation; Tool replacement, coolant opening and closing, etc.
