    • An insert (2) for milling applications in which a radial rake face (38,40) includes a concave conical portion (38,40) defined to achieve constant positive radial rake throughout the length of a radial cutting edge (18,22) at the angle of inclination (110) thereof as the insert is intended to be mounted in a cutter body. The insert includes an axial rake face (72,74) having a sloping portion defined to achieve positive axial rake as the insert is intended to be mounted in a cutter body. The upper surface (6) of the insert includes planar regions (60,66) and bend surfaces (72,74) merging smoothly with the radial rake faces (18,22) and axial rake faces (26,30) to assist in chip expulsion during cutting.
    • 一种用于铣削应用的刀片(2),其中径向前刀面(38,40)包括凹形锥形部分(38,40),所述凹形锥形部分(38,40)被限定为在径向切削刃(18,22)的整个长度上实现恒定的正向径向耙 其作为插入件的倾斜角(110)旨在安装在刀具主体中。 该插入件包括轴向前刀面(72,74),该轴向前刀面(72,74)具有倾斜部分,该倾斜部分限定为当插入件要安装在刀具主体中时实现正轴向前刀。 刀片的上表面(6)包括平坦区域(60,66)和与径向前刀面(18,22)和轴向前刀面(26,30)平滑地合并以协助芯片的弯曲表面(72,74) 切割期间的排出
