    • A milling insert (100) for shoulder milling having a positive basic shape and comprising an upper side (101) comprising a rake surface (103), a lower side (102) comprising a planar bottom surface (105), a side surface (104) extending around the periphery of the milling insert, and a cutting edge (106) formed between the side surface and the rake surface. The cutting edge comprises at least a major cutting edge portion (107a, 107b), a corner radius cutting edge portion (108a, 108b), a ramping cutting edge portion (110a, 110b), and a surface wiping cutting edge portion (109a, 109b). The side surface comprises an upper set of primary clearance surfaces (111b) and a lower set of secondary clearance surfaces (115b) comprising a plurality of planar secondary clearance surfaces (115b), wherein the upper set of primary clearance surfaces forms an overhang protruding with respect to the secondary clearance surfaces and extending around the entire upper periphery of the milling insert.
    • 一种用于肩铣的铣削刀片(100),其具有正的基本形状并且包括包括前刀面(103)的上侧(101),包括平面底面(105)的下侧(102),侧表面(104) )和在所述侧表面和所述前刀面之间形成的切削刃(106)。 切削刃至少包括主切削刃部分(107a,107b),角半径切削刃部分(108a,108b),斜坡切削刃部分(110a,110b)和表面擦拭切削刃部分(109a, 109B)。 侧表面包括上部一组主要间隙表面(111b)和一组第二间隙表面(115b),其包括多个平面二次间隙表面(115b),其中上部的一次间隙表面形成一个突出突起 相对于二次间隙表面并且围绕铣削刀片的整个上部周边延伸。
