Abstract: For properly choosing grinding parameters, predicting probable faults and processing quality, simulation of grinding based on virtual reality technology was study. Physiognomy forming mechanism of grinding wheel was analyzed and a 3D virtual grinding wheel models was built. Effects to grinding wheel physiognomy by grain size and organization number were analyzed and grain distribution was visually represented. Effect to processing quality by grinding wheel granularity, dressing parameters, grinding wheel speed, feed speed and grinding depth was simulated. And experiments were carried out for comparative analyzing. Experiments result proved the reliability and practicality of the virtual grinding wheel model.

Abstract: In this paper the modeling method of object entity in the environment of virtual is introduced and the three-dimensional simulation model of grinding wheel is established in Visual C++ programming language and OpenGL tool. The simulated experiment is made, which can indicate the effect of different parameters to grinding process. It proved the reliability and practicability of virtual wheel through comparing the simulation results and experimental data.
