Actual Cutting Speed (Vd) Conversion Coefcient Table
The actual Vc varies depending on ap and slant face angle.
Vd can be obtained by dividing the conversion coefcient 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
