Polygon turning or unround turning is defined as the turning of polygons or other unround shapes through the controlled oscillating movement of the turning tool perpendicular to the axis of rotation in very precise synchronization with the working spindle. So-called polygon cutting is also called polygon turning, wherein using a chisel, which is in turned in the correct ratio to the lathe/turning spindle, three, four, six, or eight-sides are cut on the turning work piece.
