Document Type and Number:

Japanese Patent JP2023155953

Kind Code:

A

Abstract:

To provide a cutting chip which can smoothly perform cutting of a complex shape with a recess part at high speed.SOLUTION: A cutting chip includes a cutting part. Corners forming the cutting part of the cutting chip are constituted with a plurality of curve surfaces whose curvatures are different from each other. The curve surfaces adjacent to each other share a tangent line at the connecting point. The cutting chip can accurately cut a recessed shape and can cut a flat surface or a gentle curve surface relatively close to a flat surface at high speed. Therefore, the cutting chip can smoothly perform cutting of a complex shape with the recess shape at high speed.SELECTED DRAWING: Figure 1
