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 n =(P n *A n n )/(ρ n *L n ), wherein I n  is nth-passage flow rate, P n  is nth-passage pressure drop, A n n  is nth-passage cross-sectional area raised to a power n, the power n being equal to 1 or 0.5, ρ n  is nth-passage resistivity, and L n  is nth-passage length. The method includes forming the nth-passages in the tool open to each cutting edge based on the nth-passage dimensions.

Claim (Index 14):
A cutting tool comprising:\n a tool head disposed about an axis, the tool head defining:\n a main bore disposed about the axis and open at a proximal end of the tool head, the proximal end being configured to receive a lubricant into the main bore; \n a first passage in fluid communication with the main bore and open to an exterior of the tool head at a first location that is a first radial distance from the axis, wherein a length of the first passage is related to a cross-sectional area of the first passage according to: A 1 n /L 1 =I 1 *\u03c1 1 /P 1 , wherein A 1 n  is the cross-sectional area of the first passage raised to a power n, the power n being equal to 1 or 0.5, L 1  is the length of the first passage, I 1  is a flowrate of the lubricant from the first passage, \u03c1 1  is a resistivity of the first passage, and P 1  is a pressure of the lubricant at an end of the first passage proximate to the main bore; and \n a second passage in fluid communication with the main bore and open to an exterior of the tool head at a second location that is a second radial distance from the axis, the second radial distance being greater than the first radial distance, wherein a length of the second passage is related to a cross-sectional area of the second passage according to: A 2 n /L 2 =I 2 *\u03c1 2 /P 2 , wherein A 2  is the cross-sectional area of the second passage raised to the power n, L 2  is the length of the second passage, I 2  is a flowrate of the lubricant from the second passage, \u03c1 2  is a resistivity of the second passage, and P 2  is a pressure of the lubricant at an end of the second passage proximate to the main bore; \n a first cutting edge fixedly coupled to the tool head at the first location; and \n a second cutting edge fixedly coupled to the tool head at the second location.
