  PARAMETER CALCULATION
 
  Spindle Speed Formula
  EX: Working Piece HRC40, Used by UF440A end mill
 
 4 Flutes End mill Diameter 10mm
 Please confirm the cutting speed from catalogue
EX:Finishing working for working piece (HRC40-50), Please enter cutting speed---105~120
 Please enter End mill cutting diameter.(ex:10mm)
 The spindle speed calculated—(3342-3819)
 
 
V: Milling Speed M/min
π: 3.1416
D: Diameter mm
N: Main Axis Spindle Speed RPM
 
 (RPM) =1000x     (V:Milling Speed) / 3.1416x    (cutting diameter)  
 
 
F: Feeding Speed per min mm/min
Ft: Feeding Speed per tooth mm/min
T: Flutes
 
(Ft)= (DH or ZH or RH) x ( cutting diameter)
(F)= (Ft) x (T) x (N)
