The Research of Simulation System for NC Milling Maching Driven Based on Step-NC

STEP-NC is the extension of STEP to numerical control. STEP-NC makes information bidirectional between CNC and other CAX systems, the richer information in the program file raise the level of intelligent functions of CNC. In this paper, thanks to the programme language Visual C++ and graph library OpenGL, the simulation system for NC milling machine driven on Step-NC is completed successfully. A software system based STEP-NC and its framework is designed and layout, discussed design process of a STEP-NC classes' library. Followed the key technology of the implementation of each functional module involves a lot of things are gived, The paper gives emphasis to design and realization of each functional module, including the algorithms and the flow charts. The result of program proves STEP-NC's good performance.
