Flank wear data were collected in a series of turning tests using a coated carbide tool on hardened alloy steel at a feed of 0.30 mm/rev and a depth of 4.0 mm. At a speed of 125 m/min, the tool life is 20.4 min. At a speed of 165 m/min, the tool life is 10 min. Calculate the values of n and C in the Taylor equation for tool life.
