A drill used in the manufacture of the engine parts is designed to have seven speeds. The range of hole sizes(diameter of the hole) anticipated is from 4mm to 24mm. You have been asked to determine the five spindle speeds (rev/min) given that the cutting speed is 15m/min. These spindle speeds are to be arranged in: a) arithmetic progression b) geometric progression 1000s Note: N= D Where, N = spindle speed (rev/min), s = cutting speed (m/min) and D = hole diameter (mm). ||
