Definitions

the stamp 8 experiences a tilting movement upon penetration into the workpiece 11 and while it is being guided out of it.
the angle of a flank 34 of the punch adjoining the cutting edge 28 to the workpiece 11 changes. This applies both to a loop-shaped movement of the cutting edge and the point P 0 , and to a deformed cycloid movement, in which the loop region becomes a straight piece 35 is degenerate or deformed.
