Patent ID: 7955032

Claim:
An assembly of components for forming upon consolidation of the components, a cutting insert for use in chipforming and material removal from a workpiece wherein the cutting insert receives coolant from a coolant source, the assembly comprising: a cavity member presenting opposite first and second rake surfaces and a flank surface, and a first cutting edge at the juncture of the first rake surface and the flank surface; the cavity member further having a first depression in the first rake surface and being generally adjacent to the first cutting edge; the cavity member having a first cavity channel in communication with the first depression; a first core member having a first core channel and a first flange wherein when the components are assembled, the first core channel is adjacent to the first cavity channel and the first flange is adjacent to the first depression; a second core member having a second flange containing a fifth notch and the second core member further containing a fifth notch channel opening into the fifth notch, and wherein when the components are assembled, the fifth notch is adjacent to the second rake surface and the fifth notch channel is adjacent to the first cavity channel; and whereupon consolidation of the components, the cavity member, the first core member and the second core member join together so that the first depression and the first flange define a first fluid spray chamber, and the first cavity channel and the first core channel and the fifth notch channel join together to form a fifth internal fluid passageway providing fluid communication from the fifth notch adjacent to the second rake surface to the first fluid spray chamber adjacent to the first rake surface.
