Modeling of the temperature field in the workpiece external zone as a function of the grinding wheel topography

Abstract

This paper presents an analytical model to analyze the energy partitioning in grinding based on the process parameters and the grinding wheel topography. Therefore, the energy-partitioning model of Demetriou und Lavine is coupled with a kinematic topography analysis, which predicts the kinematic engagement conditions along the contact zone using measured grinding wheel topographies. The coupling of both models allows to evaluate grinding wheels of different specifications with regard to their thermal behavior in the grinding process without preliminary experimental investigations for the first time. With the developed model, the influence of an electroplated CBN grinding wheel topography on the resulting temperature field in the workpiece external zone is investigated in creep feed grinding.
