Topic: Manufacturing
In a machining operation cutting speed is reduced by 50%. Assuming n = 0.5, C = 300 in Taylor's equation, the increase in tool life is
- A. 2
- B. 4
- C. 8
- D. 16
Answer: B. 4
Explanation: Taylor's equation is VT^n = C. V1(T1)^0.5 = V2(T2)^0.5 => V(T1)^0.5 = (V/2)(T2)^0.5 => (T2/T1)^0.5 = 2 => T2 = 4*T1. The tool life increases by a factor of 4.
