A fine blanking process produces smoother surfaces finish than a blanking process because of a higher tri-axial compressive stress caused by v-ring and smaller punch-die clearance. This work aims to study the effect of the added v-ring design parameters on the blanking process of the SPCC sheet. Three dimension and two dimension finite element models of blanking process were used for studying the effect of v-ring design parameters on the cutting force and the quality of the surface edge respectively. The FE model of the blanking process of an isotropic elastic-plastic with ductile fracture criteria material was validated with the SPCC blanking experimental tests and the results agreed well. The influence of size and shape of v-ring on cutting forces and surfaces edge were examined using Taguchi method. Four v-ring design parameters, namely the height, the radius, the angle and the distance between die and v-ring were investigated. The Taguchi main effect analysis and ANOVA results show that the distance between die edge and V-ring is the most important factor for cutting forces. The radius of v-ring edge is the most significant factor for the length of smooth-surface and the angle of V-ring is the most important factor for burr heights.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
