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 double-sided cutting insert that has a positive clearance face and includes a top portion, a bottom portion substantially identical to the top portion, and a middle portion. The inscribed diameter at the middle portion is larger than the inscribed diameter at each of the top portion and the bottom portion. The double-sided cutting insert having positive clearance face provides a simplified grinding method in order to achieve the dimensional precision required as well as reduced tooling cost allowing both positive and negative double-sided cutting inserts seat in the same insert-receiving pocket on the same tool holder.

Abstract: A cutting assembly that includes a holder containing a coolant delivery passage, and a locking pin, which has a longitudinal locking pin bore in communication with the coolant delivery passage. A clamp assembly attaches to the holder and engages a cutting insert. The clamp assembly has a diverter plate with an integral boss, which has a central boos bore, and an interior passage wherein the central boss bore is in communication with the interior passage. The longitudinal locking pin bore opens to the central boss bore whereby coolant flows into the central boss bore and to the interior passage exiting the interior passage toward 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 for use in a chipforming material removal operation that includes a cutting insert body, which has a seating surface, a flank face, and a corner cutting region at the intersection of a peripheral edge and the flank adjacent corresponding corners thereof. The cutting insert body contains a central aperture. The seating surface contains a coolant delivery trough, which has a radial orientation toward a corresponding corner cutting region. The coolant delivery trough has a radial outward end terminating at the peripheral edge and a radial inward end opening into the central aperture. There are a pair of lateral topographic regions wherein the one lateral topographic region is along one side of the coolant delivery trough and the other lateral topographic region is along other side of the coolant delivery trough.

Abstract: A split case die is used to press powder, wherein the die parts are moveable in a direction non-parallel to the direction of the pressing axis. The part produced by such a split case die has an external surface with parting line marks oriented in a direction non-perpendicular to the pressing axis.

Abstract: A coated cutting insert for use in a chip-forming material removal operation wherein the coated cutting insert includes a substrate that has a flank surface and a rake surface and the flank surface intersects the rake surface to form a cutting edge at the intersection. There is a wear-resistant coating scheme that adheres to at least a portion of the substrate. The wear-resistant coating scheme includes one or more coating layers of one or more of alumina, hafnia and zirconia. There is a wear indicating coating that adheres to at least a portion of the wear-resistant coating scheme. The wear indicating coating includes M(OxCyNz) wherein M is selected from the group comprising one or more of the following titanium, hafnium, zirconium, chromium, titanium-aluminum alloy, hafnium-aluminum alloy, zirconium-aluminum alloy, chromium-aluminum alloy, and their alloys, and x>0, y?0, z?0 and y+z>0.
