Feed Rate Calculation for the Rotary Axis

4. Calculate the feed rate in degrees per minute that is required for a rotation of 30 degrees in12.8 seconds: F=30/12.8*60=141 degrees per minute. Or apply the following formula, where: F = feed rate in inches per minute, A= C-axis rotation angle L= Length of the tool path Feed rate in degrees per minute =5 x 30 / 1.07=141 degrees per minute

Roll Length Calculator | Good Calculators

To find L, we just have to divide each side by T: π × (D 2 / 4 − d 2 / 4) / T = L. Where π is the constant (3.141592654). The formula provides us with a length of any roll of material providing we have the thickness of the material and the inner and outer diameters of the cylinder. Make sure you use the same units for all inputs.
