Abstract
A dynamic balancing machine having a rotatably driven mounting shaft for articles to be balanced has a fixture upon which known weights are mounted at two known calibration planes ralative to the shaft. Data taken by force sensors coupled to the shaft during two shaft spins with the known weights mounted in each calibration plane are used to calculate sensor output correction factors applied to unbalance data taken during the spin of a mounted unbalanced article for a pair of unbalance measurement planes spaced along the shaft. The unbalance calibration and measurement planes are axially displaced along the shaft from the location of the force sensors. The disclosure is directed toward apparatus and method for obtaining machine calibration.
