These errors are measured with a laser interferometer. STRAIGHTNESS COMPENSATION Sometimes when one axis is moved another axis position changes. This can be seen when a horizontal milling machine bar is extended. Extending the bar in the (Z-) direction causes the end of the bar to droop from its weight in the (Y-) direction.
