Abstract
Cutting machining is performed on a workpiece by making a cutting tool travel relative to the workpiece while rotating the cutting tool such that a peripheral speed of the cutting tool becomes equal to or more than a cutting speed of the cutting tool, while an outer peripheral surface and an end surface of the cutting tool function as a rake surface and a relief surface, respectively.
Claims2
A cutting device comprising:
- a rotating means for rotating a cutting tool about a rotation axis of the cutting tool;
- and
- a traveling means for making the cutting tool travel relative to a workpiece, wherein
- the rotating means and the traveling means perform cutting machining on the workpiece by making the cutting tool travel relative to the workpiece while rotating the cutting tool such that a peripheral speed of the cutting tool becomes equal to or more than a cutting speed of the cutting tool,
- wherein an outer peripheral surface and an end surface of the cutting tool function as a rake surface and a relief surface, respectively.
A cutting method of a cutting device provided with a rotating means for rotating a cutting tool about a rotation axis of the cutting tool, and a traveling means for making the cutting tool travel relative to a workpiece, comprising steps of:
- rotating an outer peripheral surface of the cutting tool about a rotation axis of the cutting tool;
- performing cutting machining on the workpiece by making the cutting tool travel relative to the workpiece, wherein an outer peripheral surface and an end surface of the cutting tool function as a rake surface and a relief surface, respectively;
- and
- controlling a peripheral speed of the cutting tool to be equal to or more than the relative traveling speed of the cutting tool.
