A Three-Dimensional Virtual Manufacturing System with High Confidence for Turning

The tool trace of turning is intensive and complex, and its virtual manufacturing with high confidence level needs to be solved urgently. In response to this pressing need, based on the general mathematical model of master-slave alignment for shaft part profiles, efficient and low-redundancy "dynamic grid" for data structure and "tool driving" exact algorithm for cutting path, the paper built a database that was flexible to adapt the data structure, packaged an Open Graphics Library (OpenGL) to form the automatic three-dimensional engine, and developed a three-dimensional virtual manufacturing system with high confidence level for turning, with numerical control code analysis, error correction, tool path simulation of turning process, parts management, all-round display, virtual manufacturing process control and other functions.
