Abstract
A plurality of cutting blades is linearly arranged on the right and left sides of a plate that is placed vertically. The cutting blades on one side are arranged so as to face downward, and the cutting blades on the other side are arranged so as to face upward. With a tool thus formed, a cutting operation is performed by making a circular motion in a plane in which the cutting blades are formed, and the cutting operation using the circular motion is repeated with the tool shifted by a predetermined pitch in a cutting direction. The tool is tilted in the cutting plane when subjected to high stress.
Claims8
A grooving method, comprising:
- cutting a workpiece by causing a tool to make a circular motion or an arc motion, wherein
- the tool includes a cutting blade group which is comprised of a plurality of cutting blades arranged linearly and whose cutting direction is a direction in which the plurality of cutting blades is arranged, and the circular motion or the arc motion is made in a plane in which the cutting blades are arranged.
A grooving tool which is mounted on a machine tool including a mechanism that moves along at least two perpendicular axes, and which performs a grooving process on a workpiece, comprising:
- a cutting blade group which is comprised of a plurality of cutting blades arranged linearly and whose cutting direction is a direction in which the plurality of cutting blades is arranged, wherein
- the cutting blade group is placed on both right and left sides of a plate that is placed vertically, and the cutting blade groups on both sides of the plate are arranged so as to be parallel to each other and so as to have opposite cutting directions to each other.
A grooving tool holding structure, comprising:
- a tool holder in which a block having attached thereto a grooving tool having a plurality of cutting blades arranged linearly is held by a base, wherein
- the grooving tool holding structure holds the tool holder on a tool base of a machine tool including a mechanism that moves along at least two perpendicular axes, and
- the block is pivotally attached to and held by the base, and the block held by the base is capable of swinging in a plane parallel to a plane in which the cutting blades are arranged.
