Actual cutting speed (Vd) conversion coefficient table

  • Vd varies depending on ap and slant face angle.
  • Vd can be obtained by dividing the conversion coefficient into the recommended cutting speed.

e.g.) Suppose tool dia. 8mm, ap=0.1mm, slant face angle 90˚: The actual Cutting speed Vd for carbon steel machining, when Vc is 150m/min at the biggest diameter, Vd can be obtained as Vd=150÷4.48=33.5m/min
