Abstract

The present study developed a 2D finite element model for simulation of creep-feed grinding process. Fully-coupled mechanical-thermal analysis was used to predict the residual stresses distribution. As in the creep-feed grinding the thermal damages are considerable, so the best and worst cooling condition i.e. flood and dry grindings were studied. Convection heat transfer coefficient was utilized to shows the effect of coolant. The results show the maximum temperature of specimen has reduced by about 52% compared to non-use of coolant. The dominate residual stresses are tensile near the surface that a steep decline in stresses was observed in flood grinding. Also, by using the electro polishing layer removal technique the non-uniform residual stresses were measured to validate the model. The results demonstrated the presented model provides good congruency with the experiments
