Analysis of residual stresses induced by dry turning of difficult-to-machine ma...
Outeiro, J. C.; Pina, J. C.; Saoubi, R. M'; Pusavec, F.; Jawahir, I. S.Critical issues in machining of difficult-to-cut materials are often associated with short tool-life and poor surface integrity, where the resulting tensile residual stresses on the machined surface significantly affect the component's fatigue life. This study presents the influence of cutting process parameters on machining performance and surface integrity generated during dry turning of Inconel 718 and auste...
On the Effects of Residual Stresses Induced by Coated and Uncoated Cutting Tool...
Outeiro, J. C.; Dias, A. M.; Jawahir, I. S.This paper presents an analysis of residual stresses in turning of AISI 316L and AISI 1045 steels with coated and uncoated tools having finite edge radii. An analytical predictive model, and experimental techniques involving X-ray diffraction and IR thermal imaging were used. Machining with coated tools produce higher superficial residual stresses, larger tensile layer thickness and higher residual stresses bel...
