Material Removal Rate - Machining Power


Chip section

A
= a x s (mm^2)

Material removal rate

V
= a x s x u (cm^3/min)

Tangential cutting force

F
= a x s x Ks ( kgf/mm^2)

Machining power

P = a x s x Ks x V / 60 x 120 x efficiency

Explaination :

  • a = depth of cut
  • s = feed in mm/rev
  • V = cutting speed in m/min
  • Ks = spesific cutting force kgf/mm^2
