Patent attributes
A cutting insert assembly for use in chipforming and material removal wherein the cutting insert assembly is received in a pocket of a cutter body wherein coolant can flow out of a pocket opening contained in the pocket. The cutting insert assembly includes a cutting insert body that presents at least two discrete cutting locations. The cutting insert body contains a coolant entry passage aligned with the pocket opening for coolant to flow through the coolant entry passage. The cutting insert body has a rake surface that contains at least two of the discrete depressions wherein each one of the discrete depressions corresponds to one of the cutting locations. Each one of the discrete depressions extends toward its corresponding cutting location. The assembly includes a diverter that is positioned adjacent to the cutting insert body wherein the diverter has a receiving opening aligned with the coolant entry passage to receive coolant through the coolant entry passage. The diverter includes a coolant trough in communication with the receiving opening wherein the coolant trough is aligned toward a selected one of the cutting locations whereby the coolant trough and the discrete depression corresponding to the selected cutting location define a conduit for the flow of coolant toward the selected cutting location.
