For a given job, the cost of tooling is \(\rm Rs.\;\frac{300C}{VT}\) and the cost of metal cutting is \(\rm Rs.\frac{18C}{V}\) where, C is constant, V is cutting speed in m/min and T is the tool life in minutes.
Taylor’s tool life equation is VT0.25 = 200.
Calculate the cutting speed (m/min) for the minimum total cost.Enter numerical value using the virtual keypad. Round off where necessary.
