Research of VR-based 3D NC Machining Environment and Key Technology

Based on the research of virtual manufacturing technology, a VR-based virtual machining environment was proposed and a general NC code translator was worked out. Special attention was given to the following aspects: work flow of virtual machining environment, frame technique of virtual machining based on its hierarchical relationship, design process of general NC code translator, triangular faceted algorithm based on work-piece model. The system of virtual manufacturing environment can realize the machining process of work-piece in real time and to analyze the machinability of virtual part.
