A New Milling 101: Milling Forces and Formulas Modern

21-03-2011  MRR = .200 x 1.64 x 19.5 = 6.4 in3/min. For horsepower at the motor (HPm), use formula: HPm = HPC/E. In determining horsepower consumption, “K” factors must be used. The “K” factor is a power constant that represents the number of cubic inches of metal per minute that can be removed by one horsepower.

Cutting torque and tangential cutting force coefficient

cut is the cutting torque, bw M is the torque needed to overcome viscous friction, and T cf is the torque needed to overcome Coulomb friction. For air cutting (T cut00), the measured spindle motor current accounts only for power losses. It is derived from Eq. 1.2 I f ¼ K lmbw 2 M þ K lmT cfw M ð1:3Þ where I f is the spindle current proportional to the power loss.

Speed Torque Curves for Stepper Motors

When selecting a stepper motor, you try to pick a motor that meets your speed and torque requirements plus some safety margin. But how do you compare motor performance between motor suppliers. Most suppliers provide speed torque characteristic curves to provide an idea of what performance can be expected from a motor. Stepper motor speed torque curves show how much torque is available
