Abstract
A mandrel for fixedly supporting a tubular workpiece during a machine tool cutting operation on the end area of the workpiece includes a pivotally mounted shaft that engages the workpiece and is mounted so as to be angularly adjustable relative to the central body of the mandrel. The angular adjustment of the shaft permits cutting operations to be performed on the end of the tubular workpiece in planes that are offset from a plane that is perpendicular to the centerline of the workpiece. The shaft is constrained to move solely within a single plane about a pivot center located adjacent the end of the workpiece on which a cutting operation is to be performed. The mandrel assembly is geometrically proportioned so that the pivot center of the mandrel shaft can be located in the cutting plane of a machine tool with which the mandrel is intended to cooperate.
