Grinding force and grinding heat: Thermal deformation of a workpiece and compensation system

Research output: Contribution to journalArticle

Abstract

The dimensional accuracy is reduced due to thermal deformation of a ground workpiece during the grinding process. The thermal deformation of the workpiece is caused by grinding heat that is proportional to tangential grinding force. Therefore, to improve the dimensional accuracy of the ground workpiece, it is necessary to understand the thermal deformation of the workpiece during the grinding process. In this article, the mechanism of thermal deformation of a workpiece and effect of the grinding heat are explained. The grinding force is important factor of thermal deformation and size generation of the workpiece in grinding. An advanced compensation system of thermal deformation of the ground workpiece by using the simulation analysis of the thermal deformation is also introduced.
