Abstract
The present invention provides a replaceable cutting insert for use in a cutting tool. The cutting insert has a recess with flat and non-coplanar side surfaces on either side of the recess. The cutting insert is retained in an insert pocket of the cutting tool by three-point contact between contact edges of the pocket and points on the side edges of the recesses on two adjacent side surfaces of the insert.
Claims23
A replaceable cutting insert for use in a cutting tool comprising:
- a top surface, a bottom surface and a plurality of side surfaces extending between the bottom and top surfaces, each side surface intersecting with the top surface at a top edge at least a section of which constitutes a cutting edge;
- a plurality of corner side surfaces, each side surface extending between a first corner side surface and a second corner side surface;
- a recess in at least one side surface, the recess being located below the top edge and having first and second opposing side edges and an upper edge therebetween;
- first and second minor side surfaces adjacent the recess, at least a portion of the first minor side surface extending from the first side edge to the first corner side surface, and at least a portion of the second minor side surface extending from the second side edge to the second corner side surface, wherein the at least a portion of the first minor side surface and the at least a portion of the second minor side surface are flat and non-coplanar, and wherein the at least a portion of the first minor side surface extends outwardly from the first corner side surface to the first side edge and the at least a portion of the second minor side surface slopes outwardly from the second corner side surface to the second side edge.
