CNC machining refers to a process method of machining parts on CNC machine tools. Generally speaking, the process procedures of CNC machine tools and traditional machine tools are the same, but obvious changes have taken place. A machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve the problems of changeable parts, small batch, complex shape and high precision, and to realize efficient and automatic machining.
CNC machining refers to the machining that the control system sends out instructions to make the cutting tool make various movements that meet the requirements, and represent the technical requirements such as the shape and size of the workpiece in the form of numbers and letters, as well as the machining process requirements. It generally refers to the process of machining parts on CNC machine tools.
CNC machine tool is a kind of machine tool controlled by computer. The computer used to control the machine tool, whether special-purpose computer or general-purpose computer, is collectively referred to as CNC system. The movement and auxiliary actions of the CNC machine tool are controlled by the commands issued by the CNC system. The instructions of the CNC 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 (CNC language or symbol) specified by the system. The numerical control system sends running or final breaking information to the servo device and other functional components according to program instructions to control various movements of the machine tool. The machine tool will stop automatically when the machining procedure of the part is finished. Any kind of numerical control machine tool can not 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; Start and stop of main shaft, change of rotation direction and speed; Direction, speed and mode of feed movement; Tool selection, length and radius compensation; Tool change, coolant on / off, etc.
