- A drilling operation is performed to create a through hole on a steel plate that is 20 mm thick. Cutting speed = 0.4 m/s, and feed = 0.20 mm/rev. The 18-mm-diameter twist drill has a point angle of 120°. Determine the following once the drill reaches full diameter: a. the machining time and, b. the metal removal rate Equation used Tm TD₂L fvA o 20 mm through hole is to be drilled in a 30 mm thick plate using a double fluted, 120° lip angle drill The drill tip is at a distance of 3 mm from the plate surface when cutting is started and an over travel of 2 mm is recommended as a margin to ensure drilling through the full thickness of the plate. If the drill rotates at 500 rev/min and the feed per tooth is 0.01 mm,find the machining time of the operation.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.
- Calculate spindle RPM and machining time for cutting a 1.5" diameter 4" long at 225 SFPM using a feed rate of 0.004".Explain how the size of an upright drill press is determined.2. Through hole of 12 mm diameter is to be drilled in a steel plate of 20 mm thickness, drilled spindle speed is 20 m/min, feed 0.25 mm/rev and drill point angle is 120°, the amount of material removed at the first 10 sec after full engagement of drill will be mm/sec.

- A two-spindle drill cuts two holes at the same time, one 1/2 inch and one 3/4 inch. The workpiece is 1.0 inches thick. Both drills have point angles of 118 degrees and the cutting speed for the material is 300 ft/min. The rotational speed of each drill can be set individually but the feed rate for both holes must be set to the same value because they move together into the material. The feed rate is set so that the total metal removal rate of both drills combined does not exceed 1.50 in3/min. Determine (a) maximum feed rate (in/min) that can be used, (b) individual feeds (in/rev) for each hole, and (c) cutting time for the operation.A mild steel specimen of Initial diameter of 30.5 mm is turned to final diameter of 27 mm for an initial length of 153 mm on a lathe machine.
