DOUBLE-SIDED TANGENTIAL CUTTING INSERT

The invention discloses a double-sided tangential cutting insert comprising a pair of cutting rake faces, a pair of major side surfaces and a pair of opposing minor side faces each having a twisted convex shape. Each of the cutting rake faces is defined between a pair of main cutting edges, a pair of full nose cutting edges, and a pair of opposing convex minor cutting edges. Each of the minor sidefaces is defined between one of the convex minor cutting edges at one of the rake faces and one of the convex minor cutting edges at the other one of the rake faces wherein, at each minor side face,a ridge line interconnects an apex of the convex minor edge at the one of the rake faces and an apex of the convex minor cutting edge at the other one of the rake faces. Other variants and embodimentsare broadly contemplated herein. 本发明公开了一种双面切向切削插入件，该双面切向切削插入件包括一对切削前刀面、一对主侧表面、以及各自具有扭曲凸状形状的一对相对的副侧面。切削前刀面中的每个切削前刀面限定在一对主切削刃、一对完整刀尖切削刃和一对相对的凸状副切削刃之间。副侧面中的每个副侧面限定在前刀面中的一个前刀面处的凸状副切削刃中的一个凸状副切削刃与前刀面中的另一个前刀面处的凸状副切削刃中的一个凸状副切削刃之间，其中在每
