Modelling of machining of AISI 316L stainless steel using finite element method

In this study, experimental and numerical analyses of cutting forces generated during turning under orthogonal cutting conditions of AISI 316L austenitic stainless steel were performed. For this purpose, the cutting tests for AISI 316L austenitic stainless steel were conducted by use of coated (TiCN+Al2O3+TiN and Al2O3) and uncoated carbide cutting tools in different cutting parameters. The cutting forces generated during cutting were measured by a Kistler 9257B type dynamometer. Deform-2D package program for numerical modeling and Johnson-Cook (J-C) material model as a material model were used. Variation of chip morphology depending on coating type and cutting parameters was also investigated in the study. The values of experimental and numerical cutting forces generated depending on cutting parameters were compared and it was observed that the results significantly were in harmony. However, the cutting temperature generated during cutting for each cutting tool, and the stress values generated on the tool were obtained by finite element analysis.
