Measuring and Analysis of Residual Stresses After Induction Hardening and Grinding

Abstract

Residual stresses are analyzed in terms of different induction surface hardening conditions and then also after finish grinding in terms of different machining conditions. Induction surface hardening creates very desirable residual stresses in hardened surface layer. Residual stresses are always of compressive nature and are usually present to the depth of the induction - hardened layer. By right selection of grinding wheel and grinding conditions taking into accounts physical and mechanical properties of the workpiece material will be kept back very favourabe compressive residual stresses in the hardened surface layer.
