Calculate value of index in Taylor’s Tool Life equation in machining
Question: In an orthogonal machining operation, the tool life obtained is 10 min at a cutting speed of 100 m/min, while at 75 m/min cutting speed, the tool life is 30 min. What is the value of index (n) in the Taylor’s tool life equation? [GATE 2009] In this problem, two cutting velocities and corresponding tool life values are given. The task is to calculate the index (or Taylor’s exponent,
