Embodiment Construction

[0034]

[0035] An embodiment of the cutting insert of the present invention will be described in detail below with reference to the drawings.

[0036] Such as Figure 1 ~ Figure 3As shown, the cutting insert (hereinafter simply referred to as insert) 1 of this embodiment has a substantially parallelogram-shaped insert body in plan view, including a bottom surface 2 forming a seat surface, an upper surface 3 with a rake surface, and a side of the face 4. Furthermore, the corners 5 (5a, 5b) located at the corners of the insert main body among the ridgelines having the upper surface 3 and the side surfaces 4, and the corners 5 (5a, 5b) located between the two corners 5, 5 of the ridgelines (that is, the Between the two ends of the ridgeline) and the cutting edge 6 connected to the two corners 5,5.

[0037] The rake surface of the upper surface 3 means a surface on which chips generated on the upper surface 3 are scraped. A through-hole 50 penetrating through the bottom surf...

Abstract

A cutting insert has a cutting edge formed at a ridge between an upper face and a side face. The side face has grooves running from the side face to the upper face to divide the cutting edge. A clearance angle in each groove is formed so that the angle is greater from one end of the cutting edge toward the other end, and as a result, the cutting insert has small cutting resistance and excellent cutting performance. Of the grooves, the groove nearest the one end of the cutting edge is preferably formed so that its width is greater from the upper face toward the lower face of the cutting insert.

Description

technical field [0001] The present invention relates to a cutting insert mounted on a cutting tool used for cutting metal materials, a cutting tool using the cutting insert, and a cutting method. Background technique [0002] In general, cutting inserts with cutting edges are often incorporated as cutting tools used for cutting metal materials and the like. For example, Patent Document 1 describes a predetermined cutting insert and a cutting tool (specifically, a milling cutter) equipped with the cutting insert. [0003] Figure 12 (a) is a side view showing a conventional cutting tool described in Patent Document 1, Figure 12 (b) means installed in Figure 12 (a) An enlarged side view of an existing cutting insert on a cutting tool. Such as Figure 12 As shown in (a), the cutting tool 100 as a milling cutter is composed of a cutting insert 101 with a cutting edge and a seat 111. The front end of the seat 111 is provided with a cutting insert pocket 110 for mounting the cu...
