Abstract
A cutting tool includes a tool body and at least one double-sided cutting insert mounted in an insert pocket of the tool body. The at least one double-sided cutting insert includes: an elliptical top surface; an elliptical bottom surface; first and second side surfaces connecting between both side ends of the top and bottom surfaces, respectively; a pair of corners connecting between both side ends of the first and second side surfaces, respectively; first and second cutting edges formed at a boundary portion between the top surface and the first side surface and a boundary portion between the bottom side surface and the second side surface and having a curved shape, respectively.
Claims25
A cutting tool for milling, comprising:
- a tool body;
- and
- at least one double-sided cutting insert mounted on the tool body;
- wherein the tool body includes at least one insert pocket for receiving the at least one double-sided cutting insert, the at least one insert pocket including a bottom wall, a side wall upwardly extending from an inner side of the bottom wall, a rear wall outwardly extending from the bottom wall and the side wall, and a male coupling portion formed at the rear wall,
- wherein the at least one double-sided cutting insert includes an elliptical top surface, an elliptical bottom surface, a pair of side surfaces connecting the top surface with the bottom surface, a first cutting edge formed between the top surface and a first side surface of the pair of side surfaces, a second cutting edge formed between the bottom surface and a second side surface of the pair of side surfaces, and a pair of corners formed at ends of the top surface and the bottom surface, the top surface and the bottom surface being 180 degrees rotationally symmetrical about a major axis (M) of an ellipse which major axis passes though the pair of corners, one of the pair of the corners having a female coupling portion formed therein to engage with the male coupling portion of the insert pocket.
