A Numerical Model to Obtain Temperature Distribution During Hard Turning of AISI 52100 Steel

Abstract

Temperature is of interest in machining because cutting tools often fail by thermal softening or temperature-activated type of wear. In this study, a numerical model was developed to obtain temperature distribution in hard turning of AISI 52100 steel. Temperature distribution model as a function of heat generation was developed using ABAQUS explicit and with an Arbitrary Lagrangian-Eulerian (ALE) formulation approach. The heat generation in the primary and the secondary stress deformation zone and along the sliding stress frictional zone at the tool–chip interface was introduced while developing a model. Johnson cook plastic flow material model was used to model the work piece material properties. A series of thermal simulations were carried out to obtain the value and region of maximum temperature at various cutting conditions. It has been observed that cutting temperature increases with the increase in cutting speed. The simulated results of the temperature distribution showed a good agreement with the results available in the literature and hence, the model developed could be used to predict the temperature distribution during hard turning of AISI 52100 steel.
