In the relation VTn = C, the value of n for carbide 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
Answer: Option B
Solution (By Examveda Team)
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 carbide tools is 0.20 to 0.25
This Question Belongs to Mechanical Engineering >> Manufacturing And Production Technology
n values:
For HSS, n=0.08-0.2
For Carbide, n=0.2-0.6
For Ceramics, n=0.5-0.8
So, answer is (C). 0.25-0.4
