Abstract
A machine forms threads on a workpiece by relatively feeding the workpiece and a cutting tool in a feeding direction while relatively rotating the workpiece and the cutting tool, and by performing a helical cutting work multiple times while carrying out relative reciprocal vibration of the workpiece and the cutting tool in a radial direction of the workpiece. The machine tool or a control device of the machine tool includes a vibration setting unit to set a pattern of vibration during each cutting work accompanied by the reciprocal vibration so that a cut portion of one cutting work partially includes a portion that has been cut in another cutting work. The machine tool and the control device prevent a long, continuous chip from becoming entangled with a workpiece or a cutting tool in the process of forming threads on the workpiece.
