摘要

Virtual machining is an important part in the research field of virtual manufacturing. This paper describes the architecture and key techniques for constructing a virtual machining system, which should be open, extendable and reconfigurable. Based on the features, functionality and application of virtual machining system, an open, modularized architecture is proposed. Then a hierarchical model of virtual machining environment is put forward, which is composed of component layer, equipment layer and environment layer. Moreover, a general NC code parser based on dynamic linked library (DLL) is reported. Users can download the DLL program for a specific NC system to extend the system's function. The flow chart of the translation algorithm is also given out. Further, the implementation of 3-Axis milling simulation is presented. The simulation method, based on triangular faceted model, has the advantages of real time rendering, changeable view points and so on. The modeling method of work-piece and the optimized machining algorithm are put forward in detail. Finally, on the basis of the techniques mentioned above, a prototype virtual machining system VRMS is developed. A Micron UCP 710 milling centre has been set up in the system. Users can verify and optimize NC code by simulating the machining process on the virtual machine tool.
