Question
In a turning operation on low carbon steel with hardness = 135 HB, the cutting speed = 180 m/min, feed = 0.35 mm/rev, and depth of cut = 6.5 mm. The
original work piece has 26 mm Diameter and 120 mm Length. How much power will the lathe draw in performing this operation if its mechanical efficiency =
90% and operator's efficiency = 82%? The specific energy is 3.8 J/mm³
