Question: In a single point turning operation with cemented carbide tool and steel work piece, it is found that the Taylor’s exponent is 0.25. If the cutting speed is reduced by 50% then what will be the change in the tool life? [GATE 2016] This problem related to the tool life in single point turning operation can be solved using the Taylor’s Tool Life equation. The well-known Taylor’s Tool Life
Question: In a machining operation, doubling the cutting speed reduces the tool life to 1/8th of the original value. What is the value of the exponent n in Taylor’s tool life equation? [GATE 2004] This is one simple problem that can be solved using Taylor’s Tool Life equation. In general, the tool life indicates the duration of time within which a cutting tool can provide satisfactory performance in machining. The
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,
