What is the distance through which the cutter has to move before the full depth of cut is acquired in milling?
(a) $\sqrt{d\left ( D-d \right )}$
(b) $\sqrt{D\left ( D-d \right )}$
(c) $\sqrt{\left ( D-d \right )d/2}$
(d) $\sqrt{D\left ( D-d \right )/2}$
Where D = diameter of the milling cutter and
d = depth of cut.
