Design a gear system to drive 4 drill bits depicted above, calculate:

-Appropriate shaft speeds for each bit based on surface speed

-Rate that the bits advance into the metal based on the most restricting of the bits in (in/min)

-Find the actual feed rate of the remaining 3 bits in (in/rev) based on the above

-Total Power required

-AGMA bending and contact stresses between the motor gear and any gear it mates to

Assume: Submit:

-Surface (cutting) speed = 300ft/min -All calculations

-Motor speed = 12,000 RPM -Schematic of the gear layout

-Standard 2 flute twist -Description of each gear

-Base material 6061-T6 -Attach copies of gear catalog pages containing your selected gears

Drill Size  Feed Rate(in/rev) Torque req. (in*lbf)
A 2.000in 0.015-0.025 137.52
B 1.500in 0.02 81.95
C 0.250in 0.005 3.24
D #13 0.004 1.9
