Claim:
1. A cutting apparatus for cutting a work, the cutting apparatus including a cutting tool having a longitudinal axis located in a plane perpendicular to a rotational axis of the work such that the cutting tool is oriented toward the rotational work axis, the cutting apparatus comprising: an angle changing unit for changing a cutting angle of the longitudinal axis of the cutting tool relative to the work in the plane perpendicular to the rotational axis; an angle detecting unit for detecting an angular position about the rotational axis of the work at which the work has largest dynamic rigidity; an angle setting unit for controlling the angle changing unit; and a cutting control unit for controlling cutting, wherein the angle setting unit controls the angle changing unit so that the cutting angle of the cutting tool becomes equal to the angle of the angular position at which the work has largest dynamic rigidity as detected by the angle detecting unit; and the cutting control unit performs cutting of the work with the cutting tool while maintaining the cutting angle set by the angle setting unit.
