Bandmill - Horsepower

hp = fpm x doc x kf x sg x 100 ÷ 144 ÷ ade x 100

hp = estimated power required (hp)
fpm = feed speed (fpm)
doc = depth of cut (inch)
kf = kerf (inch)
sg = Specific Gravity
144 = 12 inch/feet squared
ade = arbor drive efficiency %

Specific Gravity:

• Spruce = .35
• Douglas Fir = .45
• SYP = .47
• Oak = .60
