In this paper, the possibility of using laser machining on long slim steel workpieces, such as linear guide rails, was investigated to selectively induce tensile residual stresses. The approach will be used to counteract the residual stresses in a V-groove after profile grinding and to compensate for workpiece distortion. Experimental data with a …Web
