“…Destructive method relies fundamentally on stress-relaxation procedure obtained by relaxing the residual stress in some finite-volume element of the component, normally by removing some stressed material, and measuring the resulting strain change (Ruud, 1986) thus the specimen may no longer be able to re-turn to the service (Shokrieh and Ghanei Mohammadi, 2014). The material removal or cutting process changes the geometry and boundary conditions of the specimen material, and thus changes material elastic response to the (unchanged) inherent strains.…”

The chip formation in mechanical machining / cutting process involves thermal loading and mechanical loading in the form of large plastic deformations, high strain, strain rates and high temperatures in the cutting zone. These loadings usually induce plastic deformation in the form of residual stresses in the surface and sub-surface of the machined workpiece. Residual stress issue is essential to be studied in order to control the quality and fatigue life of a component or part produced by machining process. Therefore, the magnitude and depth of the residual stresses into the workpiece sub-surface is important and necessary to be measured. The objective of this paper is to discuss various study on the effects of machining parameters on residual stress and residual stress measurement methods for machined workpiece namely non-destructive, semi-destructive and destructive methods. In addition, the effect of machining process into the metallurgical conditions of the workpiece in the form of microstructural changes is also discussed.
