1)Which design do you recommend? and why?
A blanking operation is to be performed on 2.0 mm thick
cold-rolled steel (half hard). The part is circular with diameter 75.0 mm. Calculate the appropriate punch and die sizes for this operation. (Take Allowance coefficient A. = 0.075)
explain the difference between cold rolling and hot rolling and why the surface finish is better on cold-rolled metals compared to hot-rolled metals
