Normal line control type 
The feed speed of the end of the blade of the tool is the F command. The normal line control axis rotating speed is a normal
line control axis speed based on this F command.
f = F × 180 ÷ (π × R)
Normal line control axis rotating speed f = F  180  (  R)  (cutting feed rate override)[degree/min]
The following formula applies when R=0.
Normal line control axis rotating speed f = F  (cutting feed rate override)[degree/min]
F: Feed speed command[mm/min]
R: G-code control system parameter "Normal line control axis rotating radius"[mm] (length from the normal line control axis
center to the end of the blade of the tool)
*: When the normal line control axis rotating speed exceeds the cutting feed clamp speed, the speed is the cutting feed
