Approach of Characterization of the Grinding Wheel Topography as a Contribution to the Energy Modelling of Grinding Processes

A major percentage of the kinematic energy during the grinding process is converted into heat. The energy conversion is significantly influenced by the grinding wheel topography. Therefore the distribution and the shape of the cutting edges have to be considered in order to give a general model of energy conversion in grinding. This paper introduces an approach to describe and characterize the cutting edges of a grinding wheel topography, taking the elasto-plastic material behavior of the workpiece into account. Finally, based on experimental results the influence of the grinding wheel topography on energy conversion is shown using the presented model.
