Turning Horsepower Calculator. Calculate the horsepower required for a turning operation based on the feed rate, depth of cut, and cut diameter, which will determine the material removal rate (or metal removal rate). Also required is the unit power, which is a material property describing the amount of power required to cut that material.

Torque required to provide a certain level of tension to a web is total tension measured across the web times roll radius. This means the torque driving the unwind shaft must decrease at a linear ratio, relative to roll diameter, as an unwind roll decreases in size, through a machine run, to keep tension constant. Conversely, the torque driving the

Another quick reply - when we size servo motors, there is rarely a time when we use a single formula. Typically you have torque requirements for process loads (cutting / drilling / turning) + friction loads + gravitational loads on non-horizontal axes less counterbalance loads + accel / decel loads + geartrain / screw efficiencies.

A typical router at around a 1000mm/min would need an acceleration on the order of 2300rads/sec^2. The torque required to achieve this acceleration against the inertial loads is. T = J * A. [8] Which gives 1.72x10E-05 * 2300 = 0.04Nm. (the spreadsheet assumes rapids need ~1/3 the acceleration of that used for cutting).
