Simulation-Based Prediction of Process Forces for Grinding Free-Formed Surfaces on Machining Centers

Abstract

During the grinding of hard materials using cylindrically and spherically shaped mounted points – like for the machining of complex forming tools with abrasive-wear-resistant coatings – the process force is an important factor influencing the accuracy of the machining outcome. A simulation-based prediction of these forces could be used to adapt the tool path and, thereby, to keep the grinding forces at a low level. In this paper, a simulation system based on the modeling of each grain of the grinding tool and the validation of this simulation model are presented.
