Discrete Element Analysis and Experimental Validation of Forces in Grinding of Granite with Single Diamond Grain
单颗金刚石磨削花岗石中力的离散单元分析及试验验证

Grinding test was carried out to study the grinding of granite with single diamond grain.Forces were measured to investigate the mean normal and tangential forces acted on the diamond grain.The relationship between the forces and either spindle speed or the maximum thickness of the undeformed chip produced by a diamond grain was discussed.The digital models for two kinds of deferent granite were constructed by discrete element method.Based on the models,analysis was carried out to simulate the grinding proc...
