    • The present invention relates to a metal cutting insert (10) that is primarily intended for turning operations. The cutting insert comprises an upper surface (11), a lower surface (12) substantially parallel with said upper surface, and at least three side surfaces (13A, 13B) extending between said upper and lower surfaces. A transition between two adjacent side surfaces (13A, 13B) forming a rounded nose radius surface (14A) at a cutting insert corner (14). The cutting insert comprises a peripheral land (15, 15A, 15B) bridging the upper and side surfaces at least at the corner portion (14) at a chamfer angle (betaA-betaE)-An intersection of the land (15, 15A, 15B) and the nose radius surface (14A) forms a nose cutting edge (16). The nose cutting edge (16) is defined by at least one radius (R1). The cutting corner comprises at least one curved wiper edge (17,18). The chamfer angle (betaC) in a cross-section at the nose cutting edge (16) is larger than the chamfer angle in a cross-section a distance away from the nose cutting edge (16).
    • 本发明涉及主要用于车削操作的金属切削刀片(10)。 切削刀片包括上表面(11),基本上平行于所述上表面的下表面(12)和在所述上表面和下表面之间延伸的至少三个侧表面(13A,13B)。 两个相邻的侧面(13A,13B)之间在切削插入角(14)处形成圆形的前端半径表面(14A)的过渡。 所述切削刀片包括至少在所述角部(14)处以倒角角度(βA-βE)桥接所述上表面和所述侧表面的外围平台(15,15A,15B)。 - 所述平台(15,15A,15B) )和前端半径表面(14A)形成一个前刀刃(16)。 前刀刃(16)由至少一个半径(R1)限定。 切割角包括至少一个弯曲的擦拭边缘(17,18)。 在前刀刃(16)处的横截面中的倒角角(βC)大于距离鼻尖切削刃(16)的距离的横截面中的倒角角度。

The cutting insert comprises an upper surface (11), a lower surface (12) substantially parallel with said upper surface, and at least three side surfaces (13A,13B) extending between said upper and lower surfaces. A transition between two adjacent side surfaces (13A.13B) forming a rounded nose radius surface (14A) at a cutting insert corner (14). The cutting insert comprises a peripheral land (15,15A,15B) bridging the upper and side surfaces at least at the corner portion (14) at a chamfer angle (FA-FE)-An intersection of the land (15,15A,15B) and the nose radius surface (14A) forms a nose cutting edge (16;16'). The nose cutting edge (16;16') is defined by at least one radius (R1). The cutting corner comprises at least one curved wiper edge (17,18;17',18'). The chamfer angle (Fc) in a cross-section at the nose cutting edge (16; 16') is smaller than the chamfer angle in a cross-section a distance away from the nose cutting edge (16; 16'). The chamfer angle (Fc) has a minimum at a bisector (B) of the corner portion (14).
