    • A cutting insert with a substantially triangular or square basic form is particularly suited for face milling at high feed rates. It has convex cutting edges, which are each made up of a circular arc and at least one straight portion. Each cutting edge has, adjoining a cutting corner, a straight face cutting edge that merges with a main cutting edge, having 1 to 3 straight portions, a circular portion with a radius of at most 80% of the radius Ri of the inscribed circle. The cutting edges have an all-round cutting edge chamfer with a chamfer angle α. This chamfer angle α has along the cutting corners a value in the range from −10° to −20° and changes continuously along sub-portions of the face cutting edge and main cutting edge and along the circular portion to a constant value in the range from 0° to −10°.
    • 具有基本上三角形或方形基本形状的切削刀片特别适合于以高进给速率进行端面铣削。 它具有凸形切削刃,每个切削刃由圆弧和至少一个直线部分组成。 每个切削刃具有与切削角相邻的直面切削刃,其与具有1至3个直线部分的主切削刃合并,所述直线切削刃具有半径至多为内切圆半径Ri的80%的半径的圆形部分。 切削刃具有倒角角度为α的全切削刃倒角。 这个倒角角度α 沿着切削角具有在从-10°到-20°的范围内的值,并且沿着正面切削刃和主切削刃的子部分以及沿着圆形部分连续地变化到在0° °到− 10°。

    • A cutting insert of a substantially triangular or square basic form, in particular for face milling at high feed rates. It has convex cutting edges (4), which are each made up of a circular arc and at least one straight portion. Each cutting edge (4) has, adjoining a cutting corner (5), a straight face cutting edge (6), which merges with a main cutting edge (8), comprising 1 to 3 straight portions (9), by a circular portion (7) with a radius of at most 80% of the radius Ri of the inscribed circle (10). Furthermore, the cutting edges (4) have an all-round cutting edge chamfer (11), with a chamfer angle α. This chamfer angle α has along the cutting corners (5) a value in the range from -10° to -20° and changes continuously along sub-portions of the face cutting edge (6) and main cutting edge (8) and along the circular portion (7) to a constant value in the range from 0° to -10°.
