Investigation of Temperature Distribution in the Workpiece during Creep Feed Surface Grinding Using Finite Element Method

Abstract

High energy input of grinding that is dissipated as heat in grinding zone leads to thermal damage to the workpiece material. Heat transfer phenomena during deep cut grinding in general and creep feed deep cut grinding in particular is entirely different than the shallow cut grinding processes. Therefore, investigation of the temperature distribution becomes important in such situations. In the present work, a two dimensional thermal-based finite element model has been developed to investigate the transient temperature distribution within the contact zone as well as in the whole workpiece due to creep feed surface grinding. After comparing the results of the present model with the available results, the model is used for the study of effect of different input parameters such as depth of cut, workpiece speed, heat flux profile, and wheel material on transient temperature distribution.
