Analytical and Experimental Investigation of Temperature in Form Grinding

Abstract

Abstract：Based on the thermal analysis of surface grinding, according to triangular heat flux and one-dimensional linear heat conduction, a numerical model for temperature calculation in form grinding is set up. Grinding burn was most likely to happen at the place of the junction of two adjacent planes in form grinding, the coupling effect of heat source at the junction is investigated and the reason could be quantitative analyzed by this model. According to the mathematical model of energy partition ratio and real contact arc length in surface grinding, the computational method of energy partition ratio in form grinding which includes plane and inclined plane grinding is determined. Experimental measuring method of the temperature in form grinding is designed; the numerical model for temperature calculation in form grinding had been verified by tests result. The result indicated that with the coupling effect of heat source in form grinding, the junction had the highest temperature rise which would induce grinding burn.
