| Abstract: | The grinding mechanism based on single diamond grit is researched by using simulation method,and a kinematic model of single-grit grinding glass brittle materials is established after analyzing the grinding process.On the basis of the model,grinding processes in different conditions are simulated with FEM.Then,the simulation results are discussed through max tension stress,as well as grinding force,and the effects of wheel speed,depth of grinding on max tension stress and grinding force are analyzed. |

| Keywords: | single grit glass max tension stress grinding force |
