Abstract
A method for machining a workpiece, includes: rotating a rotary tool around a rotation axis, the rotary tool including at least one edge positioned on an outer periphery of the rotary tool around the rotation axis; relatively moving the rotary tool toward the workpiece in a first direction so that the at least one edge cuts the workpiece by a predetermined depth while the rotary tool is rotated around the rotation axis; and relatively moving the rotary tool with respect to the workpiece in a second direction that is substantially perpendicular to the first direction and that is inclined to a third direction substantially perpendicular to the rotation axis and the first direction.

A method for machining a workpiece, comprising:
- rotating a rotary tool around a rotation axis, the rotary tool including at least one edge positioned on an outer periphery of the rotary tool around the rotation axis;
- relatively moving the rotary tool toward the workpiece in a first direction so that the at least one edge cuts the workpiece by a predetermined depth while the rotary tool is rotated around the rotation axis;
- and
- relatively moving the rotary tool with respect to the workpiece in a second direction that is substantially perpendicular to the first direction and that is inclined to a third direction substantially perpendicular to the rotation axis and the first direction.
A machine tool comprising:
- a rotary tool comprising an outer periphery surface around a rotation axis and an at least one edge on the outer periphery surface;
- a spindle unit comprising a spindle head to rotate the rotary tool around the rotation axis, and a spindle main body to rotate the rotary tool around a first direction;
- a clamp to hold a workpiece;
- and
- a travelling tool to move the spindle unit toward the workpiece in the first direction such that the at least one edge cuts the workpiece by a predetermined depth while the spindle head rotates the rotary tool around the rotation axis, and to move the spindle unit with respect to the workpiece in a second direction that is substantially perpendicular to the first direction and that is inclined to a third direction substantially perpendicular to the rotation axis and the first direction.
