Abstract
A punch press has a punch support and die support which are rotatable about a common vertical axis, and a drive mechanism for rotating and effecting the reorientation of the tooling relative to the X and Y axes of the punch press. In this fashion, rotation of the tooling will enable reorientation of a single cutting surface, and location of various of the distinctly contoured cutting surfaces, at the desired cutting position to effect cutouts of different contour or angular orientation in a workpiece relative to the X and Y axes. The punch has a cutting portion which is of a cross section providing at least two cutting surfaces of different contours with at least at least two arcuate cutting surfaces. In accordance with one embodiment, the punch is desirably of elongated cross section with a length L along its elongated axis and a width W in its transverse axis which is less than 1/2 L. Movement of the sheet material along the X and Y axes together with such rotation of the tooling enables relatively smooth configurations to be nibbled with a single set, or limited number of sets, of tooling.
