satisfactory correlation between the strip widths, thickness to the diameter of steel pipe. The work has been focused to investigate the variation in strip thickness, while forming the strip in a rolling mill for constant roller loads and constant line velocity. It was found that there is negligible change in the thickness of the strip while ...

Punching a hole efficiently requires a precise fit between the punch and the die. Good punch and die alignment, concentric and angular, ensures that the punch can enter the die without making contact with it. Another consideration is die clearance, the difference between dimensions of the punch and the die.
