ABSTRACT:
The present invention provides an apparatus and process for shaping at least an end of a tube to a desired form by incremental axis shifting. This is accomplished by providing an apparatus including an inside/outside end sizing machine and a work table having a plurality of stop blocks associated therewith such that an angle cut perforated tube is presented to the machine at preset angles set by the stop blocks. The tube is aligned adjacent the first stop block and is presented to the inside/outside end sizing machine. The machine is then cycled and begins to align the center line of the tube with the center line of the tooling. However, the stop block prevents the tube from moving which results in the axis of the end of the tube being shifted. This process is repeated for a plurality of stop blocks which are used to alter the angle of presentation to the end sizing machine.
