General CNC machine tool working process is:
1.The computer in the numerical control unit processes the information recorded by the input device in the form of numerical and character codes.
2.The servo system and programmable controller send commands to the spindle and feed actuators.
3.The main body of the machine tool, in cooperation with the detection and feedback device, automatically controls the various actions required for workpiece processing, such as the trajectory of the tool relative to the workpiece, the amount of displacement and the feed rate, etc., so as to complete the processing of the workpiece.
The working principle of CNC machine tools can be briefly summarized as follows: through the computer control system, the processing program is converted into machine control signals, and the machine tool is controlled to carry out a variety of motions and processing operations in three-dimensional space to achieve the processing of the workpiece.
