Q15
In the relation VTn = C, the value of n for ceramic tools is
A.
0.1 to 0.2
B.
0.20 to 0.25
C.
0.25 to 0.40
D.
0.40 to 0.55
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
In Taylor tool life equation as (VTn = c)V = velocity of the cutting tool (m/min),
T = tool life (min)
c, n,, taylors coeffiecients
The value of n for ceramic tools is 0.40 to 0.55
