Abstract: Punching tool is used to cut and create blanks in a sheet metal with a certain pitch. The present day punching machine consists of a punching tool with constant pitch. The idea of this paper is to design variable punching tool with pitch varying from min to max pitch (40-180mm) using die with guidelines. The above design solves the problem of installing new tool for different pitches. Due to the variable punching tool the productivity of the company increases drastically and the setup time for the different punching tool to the machine also decreases. The initial cost of installation decreases to a maximum extent.
