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 7):
A method of manufacturing a cutting tool disposed about an axis, the cutting tool configured to have a first cutting face at a first diameter and a second cutting face at a second diameter, the method comprising:\n determining a desired flowrate of lubricant to the first cutting face and a desired flowrate of lubricant to the second cutting face; forming a main bore in the cutting tool, the main bore being disposed about the axis and configured to receive input lubricant; and forming a first passage in the cutting tool, the first passage having a first end and a second end, the first end of the first passage being in fluid communication with the main bore, the second end of the first passage being configured to provide lubricant to the first cutting face, a cross-sectional area of the first passage and a length of the first passage being calculated 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 1 or 0.5, L 1  is the length of the first passage, I 1  is the desired flowrate of lubricant to the first cutting face, \u03c1 1  is a resistivity of the first passage, and P 1  is a pressure of the lubricant at the first end of the first passage; forming a second passage in the cutting tool, the second passage having a first end and a second end, the first end of the second passage being in fluid communication with the main bore, the second end of the second passage being configured to provide lubricant to the second cutting face, a cross-sectional area of the second passage and a length of the second passage being calculated according to: A 2 n /L 2 =I 2 *\u03c1 2 /P 2 , wherein A 2 n  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 the desired flowrate to the second cutting face, \u03c1 2  is a resistivity of the second passage, and P 2  is a pressure of the lubricant at the first end of the second passage.
