Abstract
A cutting insert for use in chipforming and material removal from a workpiece wherein coolant is supplied to the cutting insert from a coolant source. The cutting insert includes at least one discrete cutting location and at least one distinct internal channel that corresponds to the cutting location. The internal channel has an inlet to receive coolant and an outlet to exit coolant. The outlet is proximate to the cutting location, and the inlet is radial inward of the outlet.
Claims10
A cutting insert for use in chipforming and material removal from a workpiece wherein coolant is supplied to the cutting insert from a coolant source, the cutting insert comprising:
- at least one discrete cutting location;
- at least one distinct internal channel that corresponds to the cutting location;
- the internal channel has an inlet to receive coolant and an outlet to exit coolant, the outlet being proximate to the cutting location, and the inlet being radial inward of the outlet;
- and
- the cutting insert comprising a mediate cutting insert body having a peripheral flank surface and a peripheral portion of opposite rake surfaces wherein each one of the cutting locations comprises a discrete cutting edge formed at intersections between the peripheral flank surface and the peripheral portions of the rake surfaces, and a pair of rake plates attached to the mediate cutting insert body wherein each one of the rake plates defining in part its corresponding one of the rake surface.
A cutting insert for use in chipforming and material removal from a workpiece wherein coolant is supplied to the cutting insert from a coolant source, the cutting insert comprising:
- a mediate cutting insert body defining a peripheral flank surface and a peripheral portion of opposite rake surfaces wherein the peripheral flank surface intersects the peripheral portion of the opposite rake surfaces to form discrete cutting locations;
- a pair of rake plates attached to the mediate cutting insert body, and each one of the rake plates defining in part its corresponding one of the rake surfaces;
- the mediate cutting insert body and the rake plates together defining a first group of a plurality of discrete internal channels and a second group of a plurality of discrete internal channels;
- each one of the first group of discrete internal channels corresponding to one of the cutting locations at the intersection of one of the rake surfaces and the peripheral flank surface, and each one of the second group of discrete internal channels corresponding to one of the cutting locations at the intersection of other of the rake surfaces and the peripheral flank surface;
- and
- each one of the first group of the discrete internal channels having an inlet opening at the other of the rake surface and an outlet opening at the one rake surface adjacent to its corresponding cutting location, and each one of the second group of the discrete internal channels having an inlet opening at the one of the rake surface and an outlet opening at the other rake surface adjacent to its corresponding cutting location.
