Answer:
V = 125.7m/min
Explanation:
Given:
L = 400 mm ≈ 0.4m
D = 150 mm ≈ 0.15m
T = 5 minutes
F = 0.30mm ≈ 0.0003m
To calculate the cutting speed, let's use the formula :
We are to find the speed, V. Let's make it the subject.
Substituting values we have:
V = 125.68 m/min ≈ 125.7 m/min
Therefore, V = 125.7m/min
