Abstract: A double-sided cutting insert that has a positive clearance face and includes a top portion, a bottom portion substantially identical to the top portion, and a middle portion. The inscribed diameter at the middle portion is larger than the inscribed diameter at each of the top portion and the bottom portion. The double-sided cutting insert having positive clearance face provides a simplified grinding method in order to achieve the dimensional precision required as well as reduced tooling cost allowing both positive and negative double-sided cutting inserts seat in the same insert-receiving pocket on the same tool holder.

Abstract: 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 side faces 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 embodiments are broadly contemplated herein.
