The main objective of the study is to improve the quality of the product and also the tool life by optimizing the punch and die clearance and sheet thickness. The quality of the product and tool life mainly depends upon the punch and dies clearance. If the punch and die clearance is too large, it leads to large burrs and poor quality, otherwise if the clearance is too small, it results in part with poor edge quality, reducing the tool life and leading to more frequent tool component replacement. By using optimal amount of die clearance, the shear cracks join; this balances the punching force and optimizes part quality and tool life. By getting the optimal amount, the optimization is used; in that genetic algorithm is a simple but powerful tool to get the optimal clearance value. This experimentation is carried out with the help of regression equation and genetic algorithm to optimize the punch and die clearance. February - April 2016 Copyright © 2016 i-manager publications.
