Abstract
With a device for reciprocating a cutting tool in small steps, the cutting tool is reciprocated in small steps in such a way that a feed mark (track of the cutting tool on the workpiece) is inverted each time the workpiece makes a round, by which the chip is varied in width and cut at a track crossing portion during the machining. Thus, chips are broken into short pieces so that the cutting efficiency and the cutting quality are improved and that the chip disposal is facilitated. Moreover, a safe turning process can be achieved.
