The workpiece temperature; Fluid cooling effectiveness and burning threshold of grinding energy in creep feed grinding

摘要

In this study, a heat transfer model based on numerical analysis of creep feed grinding is proposed. This model is verified to predict the workpiece surface temperature and to find the fraction of heat entering the workpieve. The fluid coolingeffectiveness and the effects of specific grinding conditions on the critical grinding energy when the workpiece burns are also discussed. Meanwhile, scaling analysis is performed to explain the influence that conduction behaviour in the moving directionexerts on creep feed grinding. Compared with the published data, the thermal analysis adopted in this paper is shown to be valid.
