Abstract
A double-sided cutting insert may generally comprise a top surface, a bottom surface, at least one side surface interconnecting the top surface and the bottom surface and forming at least one cutting edge, a through hole extending between the top surface and bottom surface, wherein each of the top surface and bottom surface comprise at least one anti-rotation element. The cutting insert may comprise a single anti-rotation element on the top surface and a single anti-rotation element on the bottom surface. The anti-rotation element may be proximate to the through hole. A cutting tool using the cutting inserts, as well as methods of making and using the same are also described.
Claims17
A double-sided cutting insert comprising:
- a top surface;
- a bottom surface;
- at least one side surface interconnecting the top surface and the bottom surface and defining at least one cutting edge;
- and
- a cylindrical through hole extending between the top surface and bottom surface;
- wherein each of the top surface and bottom surface comprise a plurality of seat faces evenly circumferentially spaced apart on each of the top surface and bottom surface;
- and
- wherein each of the top surface and bottom surface comprise a single anti-rotation element adjoining the through hole, and
- wherein a center line of the single anti-rotation element is substantially aligned with a center line of one of the plurality of seat faces.
A cutting tool comprising:
- a tool holder including an insert receiving pocket comprising at least one recess comprising a sidewall and a support surface for engaging the cutting insert;
- and
- a double-sided cutting insert comprising
- a top surface comprising a single top anti-rotation element;
- a bottom surface comprising a single bottom anti-rotation element;
- at least one side surface interconnecting the top surface and the bottom surface and defining at least one cutting edge;
- and
- a cylindrical through hole extending between the top surface and bottom surface;
- wherein each of the top surface and bottom surface comprise a plurality of seat faces evenly circumferentially spaced apart on each of the top surface and bottom surface;
- and
- wherein a center line of the single anti-rotation element is substantially aligned with a center line of one of the plurality of seat faces;
- and
- wherein the anti-rotation element is adjoining the through hole;
- and
- wherein one of the anti-rotation elements at least partially extends into the insert receiving pocket to prevent rotation of the cutting insert in the insert pocket.
An anti-rotation element arrangement between an insert receiving pocket comprising at least one recess in a tool holder and a double-sided cutting insert, and the cutting insert comprising a top surface, a bottom surface, at least one side surface interconnecting the top surface and the bottom surface and forming at least one cutting edge, a cylindrical through hole extending between the top surface and bottom surface, wherein each of the top surface and bottom surface comprise a plurality of seat faces evenly circumferentially spaced apart on each of the top surface and bottom surface;
- and wherein a center line of the single anti-rotation element is substantially aligned with a center line of one of the plurality of seat faces;
- and wherein each of the top surface and bottom surface comprise at least one anti-rotation element adjoining the through hole;
- and
- wherein the at least one recess cooperates with and receives the anti-rotation element to prevent rotation of the cutting insert in the insert receiving pocket.
