切削刀片、切削刀具及加工方法
摘要：
一种切削刀片(21)，包括具有第一表面、第二表面和中间表面的主体。中间表面包括大致柱状主表面(31)和从主表面径向向内延伸的至少一个凹进表面(33)，主表面(31)和凹进表面(33)在第一表面和第二表面之间延伸。切削刃(39)由主表面(31)和凹进表面(33)之间的交线限定。
摘要（英）：

A cutting insert (21) includes a body having a first surface, a second surface, and an intermediate surface. The intermediate surface includes a generally cylindrical main surface (31) and at least one recess surface (33) extending radially inwardly from the main surface, the main surface and the recess surface extending between the first surface and the second surface. Cutting edges (39) are defined by intersections between the main surface (31) and the recess surface (33).
