Milling cutter and milling insert with coolant delivery

A cutting insert for use in chipforming and material removal and wherein coolant is supplied to the cutting insert, the cutting insert comprising:

• a cutting insert body presenting at least one cutting location;
• the cutting insert body containing a coolant entry passage through which coolant can flow;
• the cutting insert body having a rake surface, the rake surface containing at least one discrete depression in communication with the coolant entry passageway, the discrete depression corresponding to the cutting location, and the discrete depression extending toward the corresponding cutting location;
• the cutting insert body further including a bottom surface, and a peripheral flank surface;
• the cutting insert body having an indention in the rake surface surrounding the coolant entry passage;
• and each one of the discrete depressions intersecting the indention so as to be in communication with the coolant entry passage;
• and
• wherein each one of the discrete depressions having a depth relative to the rake surface, and the depth decreasing in the radial outward direction.

A cutting insert assembly for use in chipforming and material removal and the cutting insert assembly being 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 comprising:

• a cutting insert body presenting at least two discrete cutting locations;
• the cutting insert body containing a coolant entry passage aligned with the pocket opening for coolant to flow through the coolant entry passage;
• and
• the cutting insert body having a rake surface containing at least two of the discrete depressions, each one of the discrete depressions corresponding to one of the cutting locations, and each one of the discrete depressions extending toward its corresponding cutting location;
• a diverter being positioned adjacent to the cutting insert body;
• the diverter having a receiving opening aligned with the coolant entry passage to receive coolant through the coolant entry passage;
• and
• the diverter including a coolant trough in communication with the receiving opening, and the coolant trough being 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.

A diverter for use in conjunction with a cutting insert, the diverter comprising:

• a central diverter body containing a receiving opening that receives coolant from the cutting insert;
• the central diverter body further containing a coolant trough in communication with the receiving opening, and the coolant trough extending in a radial outward direction from the receiving opening;
• and
• the coolant trough having a distal tapered flange.

A milling cutter assembly for use in chipforming and material removal wherein coolant is supplied to the milling cutter from a coolant source, the milling cutter comprising:

• a milling cutter body containing a coolant reservoir in communication with a coolant source, the milling cutter body further containing a pocket having a pocket opening in communication with the coolant reservoir, and
• a cutting insert body presenting at least two discrete cutting locations;
• the cutting insert body containing a coolant entry passage aligned with the pocket opening for coolant to flow through the coolant entry passage;
• the cutting insert body having a rake surface containing at least two of the discrete depressions, each one of the discrete depressions corresponding to one of the cutting locations, and each one of the discrete depressions extending toward its corresponding cutting location;
• a diverter being positioned adjacent to the cutting insert body;
• the diverter having a receiving opening aligned with the coolant entry passage to receive coolant through the coolant entry passage;
• the diverter including a coolant trough in communication with the receiving opening, and the coolant trough being aligned toward a selected one of the cutting locations whereby the coolant trough and the discrete depression corresponding to one of the selected cutting locations define a conduit for the coolant to flow toward the selected cutting location.
