Description

The G-code (ISO 6983) focuses on tool path information mainly, and it has limited information. STEP-NC (ISO 14649) includes information of tools, tool paths, workpieces, and features. Then, STEP-NC allows bidirectional data flow between CAD/CAM and CNC without any information loss. However, STEP-NC is not used in industries widely. In this study, CNC interface using STEP-NC is developed. In this system, the target feature is a freeform feature, which represented by the Region surface. Through the implemented system and machining simulation results, the superiorities of STEP-NC are also showed.
