Abstract: As method for punching in oval shapes is not readily available, press tool for punching in oval shapes is required in various industries according to their applications. There are press tools for punching in circular shape, but when shapes other than circular shape are desired, they have to design according to dimensions required by industry. As application for oval shape punching differs from industry to industry because dimensions required by industries differ from each other. As some industries require more than one oval shaped holes that is to be done in single stroke for reducing the time required for production, there is need to design such press tool which can perform such operation. Hence to have fast production of required oval size holes, there is need to develop a press tool assembly which can make accurate oval holes on metal sheets. For designing such assembly, it is very necessary to study every aspect of existing design of press tool so that changes required can be easily define. Comparison of existing design with the proposed enables us to find correct way of design.
