Abstract
A method of removing electrical runout from a measurement surface of a rotatable machine shaft is disclosed. The method includes providing a sensor adjacent to the measurement surface of the rotatable machine shaft, rotating the rotatable machine shaft, measuring a combined runout of the measurement surface, determining an angular location of one or more local valleys on the measurement surface, and re-working the measurement surface at the angular location of the one or more local valleys. Re-work may be by polishing at the one or more local valleys. Various alternative methods are disclosed, as are other aspects.
