The programming of NC punch press is to compile the processing sequence, dimension data of tool trajectory, process parameters (main motion and feed motion speed, cutting depth) and auxiliary operation (tool change, spindle positive and reverse rotation, coolant switch, tool clamping, loosening, etc.) processing information in a certain format with the code composed of specified words, numbers and symbols Processing procedures.
The content of NC programming: analyze the drawing and determine the processing process, quantity calculation, write parts processing program, make control medium, program verification and trial cutting.
Steps of NC programming:
1. Analyze the drawing and determine the process
2. Numerical calculation
3. Write parts processing program
4. Making control medium
5. Program verification and trial cutting
