CNC machine tool programming and operation mainly include two procedures: machining program writing and CNC system operation.

Machining Program Writing

1. Part Design
   Create 3D part models with CAD software, and confirm working procedures and tool paths.
   
2. Program Compilation
   Write programs via CAM software or programming codes such as G-code and M-code, covering tool paths, cutting parameters, axis movements and instructions.
   
3. Workpiece Coordinate Setting
   Define the coordinate origin and starting position to ensure accurate tool trajectories.
   
4. Program Verification & Simulation
   Adopt simulation software or professional equipment to check the validity of paths and parameters.
   
5. Storage & Import
   Save finished programs in compatible formats and import them into the CNC system.
   

CNC System Operation

1. Program Loading
   Transfer programs to the control system via USB flash drive, network or other data transmission methods.
   
2. Workpiece & Tool Parameter Setting
   Set initial axis position, workpiece dimensions as well as tool length and radius.
   
3. Tool Measurement & Calibration
   Measure and calibrate tools before processing to guarantee dimensional accuracy.
   
4. Machining Start
   Select and launch the target program on the interface. The system drives tools to cut along preset routes.
   
5. Process Monitoring
   Operators supervise processing progress and product quality, and make real-time adjustments when necessary.
   
6. Processing Completion
   The machine stops automatically after program execution. Conduct inspection and dimension measurement.
   
7. Equipment Shutdown
   Power off the machine and control system following standard procedures, and clean the working area.
   

Professional knowledge and practical experience are required for CNC programming and operation. Relevant training or professional guidance is recommended to ensure safe and proper operation.
