EXPERIMENTAL ANALYSIS OF DIE CLEARANCE DISTRIBUTION IN A PRESSTOOL ASSEMBLY

Sa？etak Shearing is one of the most widely used methods for manufacturing sheet metal components. Extensive research studies are currently being carried out in the field of tool making aiming at improving the quality of shearing. This paper analyses yet another issue arising from the production of sheet metal components. The distribution of die clearance in a progressive tool that produces sheet metal products is the focus of this study. The effect of uneven distribution of die clearance on the quality of shear is experimentally analysed. A methodology to control the uneven distribution of die clearance is also worked out
