CNC refers to computer digital control. It is a processing technology widely used in the manufacturing industry. It can also be said that it is a symbol of the current manufacturing industry. It can easily realize multi-axis linkage machining with CNC, for example, machining of curved surfaces. CNC, which is processed by ordinary machine tools, is almost impossible to complete.
In addition, the CNC can easily realize a flexible manufacturing system. The ordinary machine tool is a person directly controlling the machine tool to process, and the CNC is to control the machine tool by controlling the CNC system, thereby achieving more complicated and higher-speed machining.
CNC machine tools are computer-controlled machine tools used to control machine tools. Both special-purpose computers and general-purpose computers are collectively referred to as CNC systems. The motion and auxiliary actions of the CNC machine are controlled by the commands issued by the CNC system. The instructions of the CNC system are programmed by the programmer according to the material of the workpiece, the processing requirements, the characteristics of the machine tool and the command format (numerical language or symbol) specified by the system. The CNC system sends operational or termination information to the servos and other functional components to control various movements of the machine according to program instructions.
When the part’s machining program ends, the machine will automatically stop. For any CNC machine, if there is no program command input in its CNC system, the CNC machine will not work. The controlled actions of the machine tool generally include the starting and stopping of the machine tool; the start and stop of the spindle, the change of the direction of rotation and the speed; the direction, speed and mode of the feed motion; the selection of the tool, the compensation of the length and radius; the replacement of the tool, cooling Opening, closing, etc. of the liquid.
