A twin-spindle drill simultaneously drills one ½-in hole and one ¾" through a 1" wide work piece. Both holes are twist drill with 118° point angles. cutting speed for material is 230 ft/min. The rotation speed of each spindle can be configured individually. The feed rate of both holes must be set to the same value, since both spindles go down at the same speed. The forward speed is set in such a way that the speed total metal removal does not exceed 1.50 in3 /min. Determine: a) the velocity maximum feedrate (in/min) that can be used, b) the individual feedrates (in/rev) that result in each hole and c) the time required to drill the holes.
