Abstract

Correlation between grinding conditions and phase transformation of an alloy steel M. Mahdi & L.C. Zhang o/ Mec/mmca/ oW Mec Wromc o ABSTRACT The heat energy generated during grinding causes critical residual stresses that may affect the surface integrity of ground components. Therefore a thorough thermal analysis needs to be conducted through an appropriate modelling in relation to the grinding conditions and materials properties of workpieces. In this study, the thermal grinding conditions were simulated by inward and outward moving heat fluxes. The inward heat flux profiles were assumed to follow a triangular rule suggested by Zhang el al [1] and the outward ones were determined based on the thermal properties of the cooling media. The temperature fields induced by grinding were then simulated with the aid of the finite element method. To investigate the evolution of phase transformation associated
