Pocket Guide to Tightening Technique -

7. TORQUE AND ANGLE As mentioned above, the tightening torque is for practical reasons the criteria normally used to specify the pre-stress in the screw. The torque, or the moment of force, can be measured either dynamically, when the screw is tightened, or statically, by checking the torque with a torque wrench after tightening.

Aluminum Machining, Machining Aluminum, High Speed ...

The tools do not need to have excessively sharp cutting edges for high-speed aluminum application. No margin is desired, as that also causes a breakage problem as it provides more torque on a cutting edge. Tools with lower helix angles perform better in this application.

Understanding tangential cutting force when milling ...

When the required machining power value is about the same as the milling machine's rated power, milling productivity approaches its maximum. Torque (T s) that is applied to the spindle, and therefore to the milling cutter, is generated by the tangential cutting force (F t) and can be calculated by the formula: T s = F t × R (1)

Torque needed to rotate a cylinder | Physics Forums

The cylinder rotates slowly and is not very heavy. I believe the 315 Nm torque required to accelerate and maintain cylinder rotation will be very small compared with the torque needed to coil the tube. Use worst case values to estimate the torques. First the 12.53 kg cylinder with radius 144 mm must be accelerated to 5 RPM in 5 seconds.
