Abstract
A hobbing or gear cutting machine uses a rotary tool to rotate a cutting tool around a central axis of the cutting tool. The cutting tool has zero lead cutters, that is, the cutting tool is non-helical. A head holds the rotary tool and moves the cutting tool longitudinally along the central axis of the cutting tool. A workpiece holder holds a workpiece to be machined into a gear proximate the cutting tool. The workpiece holder selectively rotates the workpiece in conjunction with the longitudinal movement of the cutting tool via the head to cut both straight and helical gears from the workpiece.
