| Abstract | ||||
| ABSTRACT Blanking process can be simulated on computer and it will aid in die , punch design and press selection. Further effect of punch wear on fracture height and bur height in blank can be ascertained by simulation. This paper demonstrates the blanking process by simulation using ABAQUS v 6.4. For a 2mm mild steel sheet the simulation shows that for the punch force of 240 kN the crack starts at 30% punch penetration depth and punch force suddenly drops to value of 70kN and remains steady till the blanking is complete. In the elastic plastic range the experimental and simulation results agree well with rising punch force up to the point of creation of crack, however there is slight discrepancy in the down fall of force with depth of penetration of punch. With increase of the thickness of sheet the crack height is reduced and blank quality is improved. | ||||
