A numerical model incorporating the microstructure alteration for predicting residual stresses in hard machining of AISI 52100 steel

Residual stresses induced by machining processes are a consequence of thermo-mechanical and microstructural phenomena generated during the machining operation.

Summary:Residual stresses induced by machining processes are a consequence of thermo-mechanical and microstructural phenomena generated during the machining operation. Hard machining of AISI 52100 bearing steel is a typical case where the microstructural phenomena associated with white and dark layers formation influences the residual stress distribution. Unfortunately, very limited physical models are available for residual stress prediction including the microstructural effects. This paper presents an experimental and numerical approach to predict residual stresses by incorporating the microstructural phase transformations induced during machining of AISI 52100 steel.
