Prediction of grinding finished surface taking into account elastic and plastic behavior at abrasive grain and workpiece

Abstract

In the grinding process, the finished surface is created by repeated high-speed micro-cutting generated by a large number of abrasive grains. The grinding wheel surface condition is not directly transferred to the finished surface, and factors of the elastic and plastic behavior at the abrasive grain and workpiece affect the creation of the finished surface. This study proposes a simulator for generation of the finished surface, which depends on the elastic and plastic behavior at the abrasive grain and workpiece. The simulation is performed using the results of grinding wheel surface measurements. Comparison of the finished surface of the workpiece and simulation indicated that the simulation can obtain almost the same shape and the same roughness as the workpiece.
