Raja Shakarappa

Abstract: The aim is to reduce the cost of the progressive dies without compromising on the quality of output. Using the optimum resources possible in designing the progressive dies frame can effect this reduction in the cost of the progressive dies. One way of doing it will be optimizing the volume of material utilized for building the structure. An attempt has been made in this direction to reduce the volume of material. In this project work an industrial application project consisting of mass minimization of the progressive dies is considered. This progressive dies has to compensate the stresses acting on the tools, top, middle & bottom plates and to fulfill certain critical constraints. The deformation of the frame with constant thickness is described by the plain stress state equation for linear elasticity. COSMOS is the commercial software that has been used for this analysis which uses finite element method for solution. The methodology followed in this work is comparison of stresses induced in the machine for different thickness used construction of frame of the progressive dies. These stresses are compared to yield stress and considering minimum factor of safety 2.0, the thickness of frame of the progressive dies selected to reduce the volume of material utilized for building the structure and hence to reduce the cost of the machine
