Residual Stress Analysis in Orthogonal Cutting of AISI 1020 Steel

Abstract

Abstract:The aim of research work is to analyze residual stresses generated during shaper machining. This paper presents the simulation of single point cutting process by finite element method and compared with experimental work results. Taguchi L9 experimental design is used to obtain effective process parameters of rake angle, depth of cut and cutting speed. High speed cutting tool steel is used for orthogonal cutting of AISI 1020 steel on shaper machine. The residual stresses are measured by X-ray sine 2 ѱ diffraction method and finite element software used to simulate residual stress analysis. In Taguchi designed experimentation rake angle 12 0 , depth of cut 1mm, and cutting speed 220m/min has been found optimum cutting parameter for optimize compressive residual stresses.

Experimental and Numerical Investigation into Residual Stress During Turning Operation for Stainless Steel AISI 316

“…Tensile residual stresses turn for increasing service stresses which lead to the failure of components [2], as shown in Figure 1. The benefits of residual stresses are represented by compressive residual stresses: [3] The compressive residual stresses are more important for product performance, more important for the life of the product which promoted service and excludes cracks. The limitations of RS represented by tensile residual stresses: Tensile residual stresses turn for increasing service stresses and lead to premature failure of a component and tensile RS leads to distortion, corrosion and cracking.…”
