    Abstract: A clamp for a tool holder is disclosed. The clamping tool holder includes a body having an insert-receiving pocket and a threaded clamp-receiving bore with a coolant opening for receiving pressurized coolant from a coolant source. A clamp includes a threaded aperture extending from a top surface to a bottom surface and coolant passages in fluid communication with a coolant header. A clamp screw is threaded into the threaded aperture of the clamp. The clamp screw includes a plurality of coolant passages in fluid communication with the coolant opening of the body, and at least one coolant channel in fluid communication with the coolant passage. Coolant from the coolant source enters the coolant opening of the body, travels into the clamp screw, travels into each coolant passage of the clamp, and then exits the clamp in a direction toward a cutting insert-workpiece interface.

    Abstract: A clamp assembly to secure a cutting insert to a holder that includes a clamp that has a distal end and a clamp projection depending from the distal end of the clamp. There is a coolant plate that has a top plate surface and a bottom plate surface wherein the top plate surface contains a recess that receives the clamp projection upon assembly of the clamp and the coolant plate. The bottom plate surface contains a bowl having an open bowl end wherein in operation the bowl directs coolant through the open bowl end toward the cutting insert. The assembly has a positioner extending between the clamp and the coolant plate so as to maintain a position of the clamp relative to the coolant plate upon the assembly of the clamp and the coolant plate.

    Abstract: A toolholder assembly includes a toolholder body having a coolant passage and a cutting insert seated within a recess of the body. The cutting insert includes an insert orifice extending between a top face and a bottom face that aligns with the coolant passage. A lock pin includes a lock pin orifice that aligns with and is in fluid communication with the coolant passage of the body. The lock pin orifice has an outlet port to allow the fluid to flow through the lock pin orifice and exit through the outlet port. A lock pin ring includes a coolant port in fluid communication with the outlet port of the lock pin to effectively discharge cooling fluid in the direction of a cutting area of the cutting insert.

    Abstract: A cutting assembly useful for the chipforming removal of material from a workpiece at the cutting insert-workpiece interface. The cutting assembly has a holder with a coolant passage and a seat. As one option, a stud extends away from the seat and facilitates coolant flow to an insert locking cap, which attaches to the stud. The insert locking cap directs coolant flow toward the cutting insert-workpiece interface. As another option, a diverter plate has a bottom surface with a bowl and an arcuate forward surface with one or more openings. Coolant flows from the coolant passage into the bowl then exits through at least one opening in the arcuate forward surface towards the cutting insert-workpiece interface.

    Abstract: A cutting insert includes a tool carrier having a body with a pocket, and a cutting tip affixed to the pocket by brazing. The pocket is defined by a vertical back wall and a horizontal support surface. A notch is formed at the intersection between the vertical back wall and the horizontal support surface. The notch has a non-planar first portion proximate the vertical back wall and formed with a radius, R1, and a planar second portion extending between the first portion and the horizontal support surface and formed at an inclination angle with respect to a plane parallel to the horizontal support surface of the pocket. The design of the notch significantly reduces thermal stress and eliminates the formation of cracks in the pocket of the tool carrier when using an injection molding process to form the tool carrier.
