Same at the punch.Therefore, the application of clearance on punch or die will depend on whether the punched hole or the cut blank is the desired product. Hence in punching operation(where hole in the strip is the desired product), the punch is made to the correct hole size and the die opening is made oversize an amount equal to die clearance.similarly, if the blank is the desired product, the die opening size is made to the correct blank size and the punch is made smaller an amount equal to die clearance.In other words,punch controls the hole size and die opening controls the blank size.
