Operation requirements
Rotation Speed (n): n = Vc ÷ (π x D)
* n: Number of Revolutions
* Vc: Cutting Speed (Range for HSS tool is 60 - 90 m/min, or 200 - 300 ft/min)
* D: Cutting Diameter
Example: if we want to keep the cutting speed at 250 ft/min and the cutting diameter for the object is 0.3ft, the calculation for the Rotation speed would be 250 ÷ (3.14 x 0.3) = 265. So "n" would need to be around 265 revolutions per min.
Feeding Speed (f)
Recommended range: 0.003 - 0.012 in per revolution.
