    • 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). ® KIPO & WIPO 2009
    • 具有包括基本平坦的中心部分(48),基本平坦的底表面(14)和多个侧表面(16,18,20,22)的顶表面(12)的可转位切削刀片(10)。 长切削刃(24,26),角半径切削刃(28,30),小圆半径切削刃(32,34)和斜坡切削刃(36,38)被限定在顶面 (12)和一个侧表面(16,18,20,22)。 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)的刀尖半径延伸并且共混成平坦表面(94,96)。 由边缘(87,89)形成的边缘角度C小于由平坦表面(94,96)形成的就座角度B。 顶表面(12)包括在基本平坦的中心部分(48)和多个向上倾斜的前刀面之间延伸的多个向上倾斜的半径的共混物(50,52,54,56,58,60,62,64) 70,72,74,76,78,80,82,84,86,88,90,92),其在相应的半径混合物和其相应的切割边缘之间延伸,使得前刀面形成五个和 相对于顶面(12)的中心部分(48)为二十五度。 ®KIPO&WIPO 2009
