Application of Taguchi Method in process improvement of peeling of SS-202

. Abstract—The demand for high quality focuses attention on the surface condition of the product, especially the roughness of the machined surface, because of its effect on product appearance, function, and reliability. Surface quality is one of the specified customer requirements for machined parts. There are many parameters that have an effect on surface roughness such as cutting speed, feed rate, and depth of cut are known to have a large impact on surface quality. The present work studies these aspects of the peeling process applied on hardened steel using carbide inserts. Bar peeling is a method which is used to remove oxide scale, mill scale, surface cracks etc. from hot rolled or forged blanks. During peeling operation, the bar is passed through a rotating peeling head, with a radial direction of cut. The influence of cutting parameters on surface roughness was analyzed for one insert and the influence of these parameters was obtained.
