Residual stress analysis in orthogonal machining of standard and resulfurized AISI 316L steels

Abstract

Residual stresses induced by orthogonal cutting in AISI 316L standard and resulfurized steels have been investigated, with attention given to the role played by the cutting parameters, such as cutting speed, feed rate, tool geometry and tool coating. Depth profiles of residual stress have been determined using the X-ray diffraction technique. The effect of cutting conditions and tool nature on residual stresses are analyzed in association with thermal and mechanical events, recorded during the cutting tests. The tool temperature distribution has been determined by a specific CCD infrared camera technique and the cutting forces by a Kistler table set up on the lathe.
