| 摘要 |
The invention relates to a cutting insert, intended for chip removing machining, of the type that comprises a body (3) that is delimited by on one hand two opposite, first and second surfaces, which in the operative state of the cutting insert form an actively chip removing top surface and a bottom surface, respectively, and on the other hand at least one side surface, serving as a flank surface, which extends between said first and second surfaces, whereby a cutting edge is formed between the flank surface and at least one of said first and second surfaces, in which a segment (15) is included, which has the purpose of smoothening and facing the machined surface of the workpiece. According to the invention, the surface smoothening edge segment (15) is divided into at least three different part edge segments (21, 22, 23), a first one of which (21) forming a tangent point and having a certain radius (R21), is surrounded by two part edge segments (22, 23) having greater radii (R22, R23). <IMAGE> |
