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

Residual stresses induced by orthogonal cutting in AISI 316L standard and r esulfurized steels have been investigated, with attention given to the role played by the cutting parameters, such as cutting speed, feed rate, tool g eometry and tool coating. Depth profiles of residual stress have been deter mined using the X-ray diffraction technique. The effect of cutting conditio ns and tool nature on residual stresses are analyzed in association with th ermal and mechanical events, recorded during the cutting tests. The tool te mperature distribution has been determined by a specific CCD infrared camer a technique and the cutting forces by a Kistler table set up on the lathe. (C) 1999 Elsevier Science S.A.
