Embodiment Construction

[0023]

[0024] Hereinafter, cutting inserts 1 (hereinafter also simply referred to as inserts 1 ) according to non-limiting embodiments of the present invention will be described in detail with reference to the drawings. However, in each of the drawings referred to below, only main members necessary for describing each embodiment are shown in a simplified manner for convenience of description. Therefore, the blade 1 may include arbitrary structural members not shown in the referenced figures. In addition, the dimensions of the members in the drawings do not represent the dimensions of the actual structural members, the dimensional ratios of the respective members, and the like.

[0025] The blade 1 may have an upper surface 3 , a lower surface 5 , a front side 7 and a rear side 9 . The lower surface 5 may be located on the opposite side of the upper surface 3 . The front side 7 and the rear side 9 can be located between the upper surface 3 and the lower surface 5 respecti...

Abstract

A cutting insert according to an embodiment of the present invention comprises an upper surface, a lower surface, a front lateral surface, and a back lateral surface. The upper surface includes a first upper blade and an upper restraint surface. The lower surface includes a lower restraint surface. The lower restraint surface includes a V-shaped lower groove. The lower groove includes a first region, a second region, and a third region. The first region is located opposite to the upper restraint surface. The second region is located closer to the side of the front lateral surface than the first region is. The third region is located closer to the side of the back lateral surface than the first region is. The wedge angle of the first region is defined as a first angle, the wedge angle of the second region is defined as a second angle, and the wedge angle of the third region is defined as a third angle. The first angle is less than the second angle and the third angle.

Description

[0001] Cross-references to related applications [0002] This application claims priority to Japanese Patent Application No. 2019-032493 filed on February 26, 2019, and the entire disclosure of the prior application is incorporated herein by reference. technical field [0003] The present invention relates to cutting inserts used in cutting machining. Specifically, it relates to a turning tool used for turning such as grooving. Background technique [0004] As a cutting insert used when turning workpieces such as metals, for example, a cutting insert described in JP 2011-520630 A (Patent Document 1) is known. The cutting sheet (cutting insert) described in Patent Document 1 has an upper surface, a lower surface, and peripheral side surfaces. The peripheral side has a front end surface and a rear end surface. The lower surface has a V-shaped groove-shaped regulating surface extending along the central axis (longitudinal axis). The restriction surface has a first surface c...
