| 摘要 |
<p>A monolithic cutting insert (40), which receives coolant via a coolant port (32), is formed by the consolidation of a cavity member (42), a first core member (44) adjacent the first rake surface (52) of the cavity member (42), and a second core member (46) adjacent the second rake surface (54) of the cavity member (42). Cutting insert (40) contains a fifth internal fluid passageway (300), which provides fluid communication between a fifth notch (256), which is adjacent second rake surface (54) and in communication with the coolant port (32), and a first fluid spray chamber adjacent the first rake surface (52). Coolant sprays from the first fluid spray chamber toward an adjacent first cutting edge (160) adjacent the first rake surface (52).</p> |
