摘要：A machine forms threads on a workpiece by relatively feeding the workpieceand a cutting tool in a feeding direction while relatively rotating the workpiece and thecutting 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 ofthe workpiece. The machine tool or a control device of the machine tool includes avibration setting unit to set a pattern of vibration during each cutting work accompaniedby the reciprocal vibration so that a cut portion of one cutting work partially includes aportion that has been cut in another cutting work. The machine tool and the controldevice prevent a long, continuous chip from becoming entangled with a workpiece or acutting tool in the process of forming threads on the workpiece.
