Metal Shears

What is the shearing angle of punch for sheet metal shearing?

the geometry of shearing punch design

Typically, the punch and die hole diameters are chosen so that the clearance between the 2 is 1/3 the thickness of the sheet metal. (A little more for more brittle materials and a little less for more malleable ones.)

The inverse tangent of 1/3 is 18.43 degrees.
