General formula list
Formula and abbreviations Calculation of:
Cutting speed
¬$ Milling cutter [mm] Number of revolutions vc =¬¬¬¬$¬. . n
ap axial depth of cut [mm] Feed rate 1000
ae Width of cut [mm] Feed rate per tooth
vc Cutting speed [m/min] Processing time n = vc . 1000
n Numbers of revolutions - S [min-1] Rate of metal removal ¬$¬.
Required drive power
z Number of teeth [mm] vf = fz . n . z
[mm/min]
fz Feed rate per tooth [mm] fz = vf
vf Feed rate [min] n.z
Lm Machining length [cm3/min]
Tc Machining time [N/mm2] Tc = Lm
Q Rate of metal removal [kW] vf
kc Specic cutting force Q= ap . ae . vf
P Necessary power 1000
Efciency factor
P = ap . ae . vf . kc
