METHOD FOR AUTOMATICALLY GENERATING PART PROGRAM FOR USE IN STEP-NC |
摘要 |
A method for automatically generating a part program for us in a STEP-NC (STEP-Compliant Data Interface for Numerical Controls) controller in a SFP (shop-floor programming) system based on an ISO 14649 data model is provided. First, geometric kernel data is generated by interpreting a STEP physical file or an ISO 14649 part program. Then, manufacturing features are recognized from the geometric kernel data and a process plan according to the ISO 14649 is established. Thereafter, the process plan is edited and an ISO 14649 part program is generated. Subsequently, a tool path is created based on manufacturing feature information specified in the ISO 14649 part program and the produced tool path is verified in a CNC (computer-based numerical control) apparatus. By including functions of a CAD/CAPP/CAM system, the present invention makes it possible to readily generate a part program for use in the STEP-NC on the CNC controller. |
