Double-sided cutting inserts with anti-rotation features

A cutting tool comprising:

• a tool holder including an insert receiving pocket comprising at least one sidewall, a threaded hole, and a support surface for engaging a double-sided cutting insert, wherein the support surface comprises a projection comprising a cyclic conical face;
• and
• the 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 through hole extending between the top surface and bottom surface;
• wherein each of the top surface and bottom surface comprise an anti-rotation element comprising a single recess comprising a cyclic conical periphery that is complementary to the cyclic conical face of the projection.

A method of machining comprising:

• providing a cutting tool comprising
• a tool holder including an insert receiving pocket comprising a single projection comprising a cyclic conical face, and
• 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,
• chip breaker geometry, and
• a through hole extending between the top surface and bottom surface,
• wherein each of the top surface and bottom surface comprise an anti-rotation element comprising a single recess comprising a cyclic conical periphery, and
• wherein each of the top surface and bottom surface comprise:
• a seat face;
• a lower face;
• and
• at least one cyclic conical face interconnecting the seat face and lower face, and
• contacting the at least one cutting edge with a workpiece to generate a chip.
