| Abstract: | To achieve automatic generation of STEP-NC program, an STEP-NC program generator was developed. Firstly, the operating principles of the STEP NC program generator were introduced. According to inner logical relationships, the program generator was consisted of six functional modules, function and realization method for each module were expatiated. Three key technologies of program generation were studied in particular. Finally, exampled with a AP203 file including a planar face, hole, pocket, the whole STEP-NC program was generated based on ISO14649 by the proposed program generator. A cutting simulation was performed on the generated STEP-NC program by STEP-NC milling machining simulation system. Result proved the feasibility and effectiveness of the STEPNC program generator. |
