Machine tool backlash adjustment compensation parameters

Backlash can be tested with indicators, lasers, ballbars or other measuring devices to determine how much motion is lost when an axis reverses direction. This value is entered in the machines parameters, so when an axis changes direction, it compensates the amount in the parameter to determine when the axis will physically move.
