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.
Claims8
A method for machining a workpiece, comprising:
- rotating a rotary tool around a rotation axis, the rotary tool including an edge positioned on an outer periphery of the rotary tool around the rotation axis, the rotary tool being oriented such that, when the edge contacts the workpiece, a tangential rotating direction of the edge is at an inclined angle with respect to a feeding direction for machining the workpiece;
- relatively moving the rotary tool toward the workpiece so that the edge cuts the workpiece by a first predetermined depth while the rotary tool is rotated around the rotation axis;
- relatively moving the rotary tool with respect to the workpiece in the feeding direction;
- repeating the relative movement of the rotary tool toward the workpiece so that the edge cuts the workpiece to a second predetermined depth that is greater than the first predetermined depth;
- and
- repeating the relative movement of the rotary tool and the workpiece in the feeding direction.
