Problem
In a machine operation, with a bar with diameter(D) = 80mm, is cut with a blade that has a feed rate of 0.8mm/rev. The length of the cut(L) is 260mm.
The cutting time(T) is given by T = L/ feed rate * N. Where N is the spindle speed(N) and is given by the formula N = V/ pi * D. where V is the cutting speed.
Develop a c++ program that computes and displays the cutting time for a range of cutting speeds(all in meters/min). The user should input the corresponding min and max speed aswell as the incremental speed.
