Abstract
A rotary cutting tool, such as a slotting cutter, includes a cutter body rotatable in a predetermined direction on a central axis perpendicular to a plane of the cutter body. A plurality of cutting insert-receiving pockets are formed at predetermined locations about the cutter body. A cantilevered member can be integrally formed in the cutter body or attached to the cutter body as a separate component. A tip of the cantilevered member at least partially extends into each insert-receiving pocket such that the cantilevered member exerts a biasing force against a cutting insert at a location so as to counteract a tendency of the cutting insert to rotate within the insert-receiving pocket during a cutting operation.
Claims19
A rotary cutting tool, comprising:
- a cutter body rotatable in a predetermined direction on a central axis;
- a plurality of insert-receiving pockets formed at predetermined locations about the cutter body, each insert-receiving pocket including a radial support surface;
- and
- a cantilevered member integrally formed in the cutter body such that a tip of the cantilevered member at least partially extends into each insert-receiving pocket,
- wherein the cantilevered member extends in a radial direction from the cutter body,
- wherein the cantilevered member exerts a biasing force against a cutting insert at a location so as to counteract a tendency of the cutting insert to rotate within the insert-receiving pocket during a cutting operation.
A slotting cutter, comprising:
- a disc-like cutter body rotatable in a predetermined direction on a central axis perpendicular to a plane of the cutter body;
- a plurality of insert-receiving pockets formed about a perimeter of the body, each insert-receiving pocket including a bottom support surface, a radial support surface and an axial support surface;
- and
- a cantilevered member formed in the cutter body such that a tip of the cantilevered member at least partially extends into each insert-receiving pocket,
- wherein the cantilevered member exerts a biasing force against a cutting insert at a location so as to counteract a tendency of the cutting insert to rotate within the insert-receiving pocket during a cutting operation.
A rotary cutting tool, comprising:
- a cutter body rotatable in a predetermined direction on a central axis;
- a plurality of insert-receiving pockets formed at predetermined locations about the cutter body, each insert-receiving pocket including a radial support surface;
- and
- a cantilevered member, comprising a component separate from the cutter body, which is attached to the cutter body such that a tip of the cantilevered member at least partially extends in a radial direction into each insert-receiving pocket,
- wherein the cantilevered member exerts a biasing force against a cutting insert at a location so as to counteract a tendency of the cutting insert to rotate within the insert-receiving pocket during a cutting operation.
