ABSTRACT:
A punch press has a ram assembly with a lower portion which is rotatable and reciprocatable about a vertical axis and, a die holder which is rotatable about the same axis. A gear mechanism is coupled between a drive motor and the lower portion of the ram assembly and the die holder to effect simultaneous rotation thereof, which effects reorientation of the tooling relative to the X and Y axes of the punch press. In this fashion, rotation of the tooling will enable a single set of tooling to effect cutouts of different orientation in a workpiece relative to the X and Y axes, and movement of the sheet material along the X and Y axes together with such rotation of the tooling enables complex configurations to be nibbled or cutout with a limited number of sets of tools.
