Mill Open Gear Backlash

Z axis backlash reduction.1 - rick.sparber.org

When I plunge cut with an end mill, there is a downward force as the flutes try to screw themselves into the metal. The rack pulls down on the engaged tooth of the pinion gear. When I side mill, there is an upward force so the rack rises and lifts up on the adjacent tooth in the pinion gear. Backlash as a function of cutting action is not nice.
