Research & Exploitation of NC Simulation Control System Based on OpenGL

OpenGL is the API of 3D graphic running in window system. With the powerful function in transacting interactive graphics, when used in simulation system, it can show the actual surface or performance of the 3D objects.Using Object-Oriented-Programming technique and MFC class library,a lathe control system dynamically simulating NC machining process was researched and developed in windows system with the tool platform of Microsoft Visual C++ 6 0. In this simulation system, after the brief analysis of the flow of OpenGL data streams and its use in NC simulation system,the whole framework of NC machining simulation system was constructed and the system functions modules were analyzed.This system is mostly applicable for lathe turning cutting process, the sample of simulative process demonstrates that this simulation system has good stability, expansibility and maintenance.
