diagram for a gearbox with 7 speeds

please help me d min = 15
d max = 54
cutting speed = 24
loss of productivity = 20 %
s = 0,22
t=60

1 Answer

we use the formula:

Productivity = (Cutting speed * (1 - Loss of productivity)) / (s * t)

Substituting the given values:

Productivity = (24 * (1 - 0.20)) / (0.22 * 60)

Productivity ≈ 0.825 units per minute
