Thermal Modeling and Analysis for Grinding Operation

This paper focuses on the effects of heat source profiles during thermal analysis of grinding. Three different models of heat source, namely triangular model, parabolic model and elliptic model, have been suggested and their numeric formulas are provided. These models take into account of the variation of heat flux along the contact zone, so as to improve the accuracy of numeric results. Finite Element Analysis (FEA) is utilized to investigate the temperature distributions under different thermal models and the effects of two profile parameters (eta and xi). The result is a) peak temperature decreases as eta increases and the location of peak value moves backwards simultaneously; b) peak temperature decreases as xi increases and the location of peak value moves forwards simultaneously.
