U = 90*10 3 KN/m 2 h = 1.02 mm = 1.02 * 10 -3 m<br />
Force for Blanking:<br />
Fblanking = 0.5UhLs<br />
Where Ls = length <strong>to</strong> be sheared = 43.45 cm = 0.4325 m<br />
Fblanking = 19.85 KN<br />
Force for Punching:<br />
Fpunching = 0.5UhLs<br />
Where<br />
Ls = 260 mm = 0.26m<br />
Fpunching = 11.93 KN<br />
Force for Embossing:<br />
For one embossing<br />
Fembossing = UhLsSinθ<br />
= 5.06 since Ls = 0.078m<br />
Total Fembossing = 6 * 5.06 (As <strong>the</strong>y are six embossing effects)<br />
