Abstract
A machine for processing a workpiece is disclosed. Preferably, the machine includes a circular saw blade that may be positionable about multiple axes with respect to the workpiece. The machine is particularly suited for processing an elongated workpiece. The machine includes two gripping mechanisms and three vises that cooperate with one another to move an elongated workpiece into position, hold the workpiece while it is being processed, and remove the workpiece from the machine. The machine also includes a computer system that controls the orientation of the saw blade and the movements of the vises and gripping mechanisms.
