Question: Turning tests using cemented carbide tooling resulted in a 1.5-min tool life at a cutting speed = 4.3 m/s and a 22-min tool life

Turning tests using cemented carbide tooling resulted in a 1.5-min tool life

Turning tests using cemented carbide tooling resulted in a 1.5-min tool life at a cutting speed = 4.3 m/s and a 22-min tool life at a speed = 1.8 m/s. (a) Find the n and C values in the Taylor Tool Life equation. (b) Project how long the tool would last at a speed of 0.8 m/s. C = m/min V = m/min n = At v = 0.8 m/s V = m/min T = min (7)
