B/ A rectangular aluminum block is drilled at a depth of 40 mm using a drill that has two cutting edges. The following observations were made: Block thickness 60mm Drill diameter 25mm Point angle Cutting speed 118° 25 m/min Feed 0.25 mm/rev Determine: removal volume rate after the drill bit reaches full diameter and cutting time of the operation.
