The working principle of a CNC machine tool is to represent the various operations required for the processing process (such as spindle speed, workpiece release and clamping, feed and retreat, driving and parking, automatic shutdown of coolant) and steps

The working principle of a CNC machine tool is to represent the various operations required for the processing process (such as spindle speed, workpiece release and clamping, feed and retreat, driving and parking, automatic shutdown of coolant) and steps, as well as the shape and size of the workpiece, in a digital code, through a control medium (such as perforated paper tape or disk, etc.) The digital information is fed into the CNC device, the CNC device processes and calculates the input information, sends out various control signals, and controls the servo system or other drive components of the machine tool to automatically process the required workpieces.Therefore, the key to CNC machining is the acquisition of machining data and process parameters, that is, CNC programming.CNC machining generally includes the following contents:
picture
(1) Analyze the drawings and determine the parts that need CNC machining;
(2) Use graphics software (such as CAXA manufacturing engineers) to model parts that require CNC machining;
(3) According to the processing conditions, select the appropriate processing parameters and generate the processing trajectory (including roughing, semi-finishing, and finishing trajectories);
(4) Simulation inspection of trajectory;
(5) Generate G code;
(6), Passed to the machine tool for processing.
