摘要:
An indexable cutting insert (10) having a top surface (12) including a substantially planar central portion (48), a substantially planar bottom surface (14), and a plurality of side surfaces (16, 18, 20, 22). A long cutting edge (24, 26), a corner radius cutting edge (28, 30), a facet radius cutting edge (32, 34), and ramping cutting edges (36, 38) are defined at an intersection between the top surface (12) and one of the side surfaces (16, 18, 20, 22). A margin (87, 89) extends around a nose radius of the side surfaces (16, 18, 20, 22). A margin (87, 89) extends around a nose radius of the cutting insert (10) and blends into a flat surface (94, 96). A margin angle, C, formed by the margins (87, 89) is less than a seating angle, B, formed by the flat surfaces (94, 96). The top surface (12) includes a plurality of upward sloping radius blends (50, 52, 54, 56, 58, 60, 62, 64) extending between the substantially planar central portion (48) and a plurality of upward sloping rake faces (70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92) extending between a respective radius blend and its respective cutting edge such that the rake face forms an angle, A, of between five and twenty-five degrees with respect to the central portion (48) of the top surface (12).
摘要(中):
具有包括基本平坦的中央部分(48),基本平坦的底部表面(14)和多个侧表面(16)的顶部表面(12)的可转位切削刀片(10) 18,20,22)。 在顶表面(24,26),拐角半径切削刃(28,30),小面半径切削刃(32,34)和斜切刃(36,38) (12)和侧表面(16,18,20,22)中的一个。 边缘(87,89)围绕侧表面(16,18,20,22)的鼻部半径延伸。 边缘(87,89)围绕切削刀片(10)的鼻部半径延伸并且混合到平坦表面(94,96)中。 由边缘(87,89)形成的边缘角C小于由平坦表面(94,96)形成的就座角B。 顶面(12)包括多个向上倾斜的半径混合物(50,52,54,56,58,60,62,64),该多个向上倾斜的半径混合物在大致平坦的中央部分(48)和多个向上倾斜的前刀面 在相应的半径混合物和其相应的切削刃之间延伸,使得前刀面形成介于5°和50°之间的角度A, 相对于顶面(12)的中心部分(48)为二十五度。 p>
