CNC machine tools are basically the same as ordinary machine tools in terms of processing technology and surface forming methods, but there are significant differences in the principles and methods of achieving automatic control. CNC machine tools use digital information to achieve automatic control. Therefore, it is necessary to first compile processing information related to the workpiece, such as the size parameters of the relative motion trajectory between the workpiece and the tool, cutting parameters, and various auxiliary operations, into a code using specified text, numbers, and symbols, and write a processing program in a certain format. Then, input the processing program into the data mixing device. After processing and calculation by a CNC device, the moving components of each coordinate axis are sent to the driving circuit of each axis. After conversion and amplification, they are used for the drive of servo motors to drive the movement of each axis, and feedback control is carried out to ensure that the cutting tools, workpieces, and other auxiliary equipment move in an orderly manner according to the sequence, trajectory, and parameters specified in the program, thus processing the required parts.
CNC machine tools are indispensable CNC machining center equipment in our daily production. Their appearance has greatly changed our life. A friend said that if FANUC disappears, the world will stop running. This is not alarmist. FANUC system has the highest contribution in the field of international machine tools. Many high-tech CNC systems are FANUC systems.
