Abstract
A cutting system may include a tool and a stationary fixture. The tool may include a cam connected with a cutting insert. The stationary fixture may be spaced apart from the tool. The stationary fixture may include a moveable indexing pin moveable relative to the stationary fixture. The cam of the tool may be configured to be moved into contact with the moveable indexing pin of the stationary fixture, and the moveable indexing pin of the stationary fixture may be configured to cause the cam to rotate thereby indexing the cutting insert.
Claims25
A cutting system comprising:
- a tool comprising a cam;
- a cutting insert operatively connected to the cam;
- and
- a stationary fixture spaced apart from the tool, the stationary fixture comprising a moveable indexing pin moveable relative to the stationary fixture;
- wherein the cam is configured to be moved into contact with the moveable indexing pin of the stationary fixture;
- wherein the cam includes at least one slot formed therein, the slot having a longitudinal axis disposed at a non-parallel angle relative to an axis of rotation of the cam;
- and
- wherein relative movement between the tool and the stationary fixture causes the indexing pin to enter the slot and travel along the slot to impart rotational movement to the cam about the axis of rotation.
The cutting system of 2 wherein the cam comprises a circumferential slot extending around the outer surface of the cam, the spaced-apart slots intersecting the circumferential slot.
A cutting system comprising:
- a machine tool;
- a processor;
- a tool comprising a cam;
- a cutting insert operatively connected to the cam;
- and
- a stationary fixture spaced apart from the tool, the stationary fixture comprising a stationary pin and a moveable indexing pin moveable relative to the stationary fixture;
- wherein the processor is configured to move the machine tool to move the cam into contact with the stationary pin and the moveable indexing pin of the stationary fixture;
- wherein the cam includes at least one slot formed therein, the slot having a longitudinal axis disposed at a non-parallel angle relative to an axis of rotation of the cam;
- and
- wherein relative movement between the tool and the stationary fixture causes the indexing pin to enter the slot and travel along the slot to impart rotational movement to the cam about the axis of rotation.
The cutting system of 12 wherein the cam comprises a circumferential slot extending around the outer surface of the cam, the spaced-apart slots intersecting the circumferential slot.
A method of indexing a cutting insert of a tool comprising:
- moving the tool to dispose a cam of the tool into contact with a moveable indexing pin of a stationary fixture;
- disposing the moveable indexing pin within at least one slot formed in the cam, the slot having a longitudinal axis disposed at a non-parallel angle relative to an axis of rotation of the cam;
- moving the tool relative to the stationary fixture to cause the moveable indexing pin to travel along the slot;
- and
- imparting rotational movement to the cam about the axis of rotation by the travel of the moveable indexing pin along the slot, thereby causing the cutting insert of the tool to index.
