    摘要： A cutting insert according to the present invention is a cutting insert having a first end surface, a second end surface opposing the first end surface, and a peripheral side surface connecting the first and second end surfaces, wherein the peripheral side surface includes a rake surface, a front flank and a first cutting edge located in an intersecting edge between the rake surface and the front flank. The first end surface includes a central surface and a side flank located closer to the front flank as compared to the central surface. As viewed from a direction facing the rake surface, an intersecting edge between the central surface and the peripheral side surface serves as a first edge, and an intersecting edge between the side flank and the peripheral side surface serves as a second edge, and when, as viewed from the direction facing the rake surface, an angle formed by the first cutting edge and the first edge serves as a first angle α, and an angle formed by the first cutting edge and the second edge serves as a second angle β, the first angle α is smaller than the second angle β.

    摘要翻译： 根据本发明的切削刀片是具有第一端面，与第一端面相对的第二端面以及连接第一端面和第二端面的周边侧面的切削刀片，其中，周边侧面包括前刀面 位于前刀面和前侧面之间的相交边缘中的前侧面和第一切削刃。 与中心表面相比，第一端面包括中心表面和位于更靠近前侧面的侧面。 从与前刀面相对的方向观察，中央面与周围侧面的交叉边缘成为第一边缘，侧面与周边侧面的交叉边缘成为第二边缘， 当从与前刀面对置的方向观察时，第一切削刃与第一边缘所成的角度为第一角度α，第一切削刃与第二边缘所成的角度为第二角度β， 第一角度α小于第二角度β。

    摘要： During grooving or cutting-off, chips are curled into a flat spiral spring shape with no lateral displacement, cut to an appropriate curl length, and then discharged, irrespective of their thickness that varies according to the amount of feed.
    Inclined surfaces 51 and 52 are formed on a rake face 40 such that they incline downward toward a central portion between side cutting edges 120, and a recessed groove 60 is formed in the central portion between the inclined surfaces such that the recessed groove 60 extends from the the end cutting edge 110 in the forward-rearward direction. The groove width of the recessed groove 60 gradually increases from the position of the end cutting edge 110 toward the rear, then gradually decreases such that the recessed groove 60 has a narrowest portion at a position P2 forward of the position P3 of an upper end 45 of a breaker wall 43 and rearward of a positive rake angle rear end position P1, and then gradually increases toward the rear up to the position P3 of the upper end 45 of the breaker wall 43.

    摘要： A holder according to one embodiment has a rod shape and includes a head portion located at a front end side. The head portion includes an upper jaw portion and a lower jaw portion located at a front end, an insert pocket located between the upper jaw portion and the lower jaw portion, a first wall surface located at an upper surface of the upper jaw portion and inclined in an extending manner from one side surface side, a second wall surface located closer to a rear end side than the first wall surface and inclined upward, a concave-shaped third wall surface located closer to the rear end side than the second wall surface, and a fourth wall surface inclined upward as the fourth wall surface extends away from the third wall surface. The third wall surface is concave downward from an upper end of the second wall surface.

    摘要： A cutting member comprising a cutting edge (S1, S2, Si,) defining a cutting envelope and configured for removing material from a workpiece leaving therein a corner of angle α. The cutting edge comprises a first cutting segment (Si) and a second cutting segment (S2) spaced from the first cutting segment (S2). Respective first and second imaginary tangents (T1, T2) of the first and second cutting segments (S1, S2) intersect one another at point O located outside the cutting envelope, forming an angle corresponding to angle α, thereby defining a cutting frame at least a portion of which extends beyond the cutting envelope. The cutting edge further comprises an adjoining cutting segment (Si), extending between and bridging the first cutting segment (S1) and the second cutting segment (S2), and at least partially contained within the cutting frame. The cutting member further comprises at least one auxiliary cutting element (AT1, AT2) comprising an auxiliary cutting edge (CE′, CE″) extending generally along one of the imaginary tangents (T1 , T2) and beyond the cutting envelope. The auxiliary cutting edge (CE′, CE″) does not intersect the other of the imaginary tangents (CE″, CE′) and/or a bisector (B) of the angle α.

    摘要： A cutting tool holder blade (100,101) is formed of hard metal such as cemented carbide, the cutting tool holder blade (100,101) having a front plane (F), a perpendicular mid-plane (P). An insert pocket (104) of the holder blade (100,101) has a base jaw (106) and a clamping jaw (110) resiliently connected to the base jaw (106) in a unitary one piece construction. The base jaw (106) has a base jaw abutment surface (108) and the clamping jaw (110) has a clamping surface (112) facing opposite the base jaw abutment surface (108), and an insert stop surface (114). A curved inner surface (116) extends from the base jaw abutment surface(108) towards and along the clamping jaw (110), the curved inner surface (116) having a front extremity portion (118). The clamping jaw (110) is narrowed down adjacent the front extremity portion (118), such that the clamping surface (112) overhangs the front extremity portion (118) of the curved inner surface (116), in a direction towards the base jaw (106) and away from the front plane (F).
