Machining Induced Surface Integrity Aspects of Stainless Steels: A Review

Abstract

Abstract Surface integrity (SI) is one of the important measures of machinability, because it affects the functional aspects of the finished components, such as fatigue strength and resistance to corrosion. Various methods of generating the most favorable residual stress on the machined surfaces for improvement of fatigue life like, variations in machining parameters, tool geometry and work material property enhancement are replacing the age-old techniques of shot peening and laser shock peening. These new methods are promising, because of their functional ease of implementation and significant cost reduction through such implementation. This study presents a brief review of the extant literature on machining induced surface integrity aspects of difficult to cut materials like, Duplex Stainless Steels (DSS). The need of predictive modeling for machining induced surface integrity aspects of Duplex Stainless Steels is highlighted as an outcome of this literature review
