Evolution Mechanism and Dynamic Model of Grinding Temperature Field Based on Discrete Heat Source

Abstract

This chapter first analyzes the kinematic law of wear particles in sliding, plowing, and cutting stages, and reveals the interference mechanical behavior of wear particles and workpieces. Furthermore, the specific energy models of grinding at different stages are established, and the heat distribution mechanism of effective grinding particles is revealed. Finally, an experimental method for measuring workpiece temperature at different positions by using bipolar thermocouple array is designed. The results show that the measured grinding temperatures at different cutting depths agree with the numerical results.
