Abstract
A tool-main-spindle, whose cutting angle can be changed, is translated by an X-axis moving mechanism portion on an X-axis provided in a plane perpendicular to an axis of a work, and is translated on a Y-axis by a Y-axis moving mechanism portion. Cutting of the work is performed by setting the cutting angle of the tool-main-spindle to an angle of the cutting tool at which the work has large dynamic rigidity, and causing an axis of a cutting tool to cross the work axis, and cutting the work with the cutting tool toward the axis of the work by cooperatively operating the X-axis moving mechanism portion and the Y-axis moving mechanism portion.
Claims5
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.
