Estimating Machining Time for Turning

In the case of turning the formula for machine time is

T = [L+A]/[frN]

Where T = machining time in minutes
L = length of the workpiece
A = an allowance for tool approach and exit, normally 2 to 5 mm
fr   = feed rate (mm per revolution of the workpiece)
N = revolutions of the workpiece in rev per minute
