Example: By taking 0.23–0.10 mm (0.009–0.004 inch) in cutting depth per pass (radial infeed), the full cutting depth ( a p ), and the profile depth of the thread (0.94 mm (0.037 inch)), is turned on a 1.5 mm (0.06 ...
Torque is the rotational equivalence of linear force. Speed measures the distance covered in unit time. The relation between torque and speed are inversely proportional to each other. The torque of a rotating object can be mathematically written as the ratio of power and angular velocity. Torque and Speed Formula
In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment, moment of force, rotational force or turning effect, depending on the field of study.It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers.
$begingroup$ The real thrust of my answer is that a simple google search for "milling torque formula" or "milling torque calculator" will answer this question. The question is too vague (as to the desired type of milling) to cite a specific formula. $endgroup$ – Ian. Nov 11 '16 at 13:08.
