To provide a low-priced and high-precision machined part with the minimum number of compact machine tools by machining the part, while giving amplitude to the top end of a cutting tool mounted on an oscillating device with regard to the machining method of a plane which requires an inclination against a rotation axis core in machining.
A work 6 is machined by allowing the amplitude of the sinusoidal oscillation to match with the rotation cycle of the work 6, while gradually changing the amplitude of the sinusoidal oscillation by attenuating or amplifying the rotation of the cutting tool 1 fixed to the oscillating device 11 in one cycle sinusoidal oscillation per rotation and the amplitude of the sinusoidal oscillation in the variation of a primary straight line against the center of the rotation axis.
