Abstract: This paper is about cost reduction of fix jaw of rear vice by weight reduction. Rear vice of horizontal band saw machine used for clamping work piece during cutting operation. It has two jaws- Fix jaw and movable jaw. Movable jaw attached to hydraulic cylinder which applies force to hold work piece between these two jaws. Reduce weight of components help to minimize load on environmental resources.This efforts for reduction of weight by using topology optimization. fix jaws has been modeled using solid works First conducted analysis on existing jaws with calculating the forces acting on jaws in order to find out Max. Displacement and stress induced. These analyses were carried using Altair Hyperworks and solver used is optistuct. Again conducted topology optimization with applying manufacturing constrain like minimum member size and single type draw direction. Again prepare cad model as per topology result and carried analysis on optimized model. from that analyzed results, Displacement and stress are lower than existing model. From result it was found that current design is safe also save material and cost of component, Finally we reduced cost by 244/- and total reduced weight by 24 % of current fix jaw model. Topology optimization analysis is carried out in Hyperworks which yielded in weight optimized.
