WEIGHT OPTIMIZATION OF FIX JAW OF REAR VICE OF HORIZONTAL BAND SAW MACHINE USING TOPOLOGY OPTIMIZATION

Prashant H. Patil, Suresh S. Patil

Abstract: Horizontal band saw machine is an important machine tool in mechanical workshop. This paper is about Weight reduction of fix jaw of rear vice. Rear vice 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 jaw. 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 based on topology result and carried analysis on optimized model. from the 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 total weight by 12 % of current fix jaw model. Topology optimization analysis is carried out in Hyperworks which yielded in weight optimized.
