Abstract
A cutting tool and method of manufacturing a tool including determining desired flowrates to cutting edges. The method includes calculating pressure drop and passage dimensions for each of an nth-number of passages to the cutting edges based on I=(P*A)/(ρ*L), wherein Iis nth-passage flow rate, Pis nth-passage pressure drop, Ais nth-passage cross-sectional area raised to a power n, the power n being equal to 1 or 0.5, ρis nth-passage resistivity, and Lis nth-passage length. The method includes forming the nth-passages in the tool open to each cutting edge based on the nth-passage dimensions.
