method and device for generating signals, the biggest exzentrizitaeten of several drehspindeln reflect in machine tools

摘要

An apparatus and method for producing a signal representing the most significant eccentricities of a plurality of rotating spindles in a multiple spindle machine tool. The eccentricities of each spindle are monitored to produce a plurality of signals as a function of the eccentricities of the separate spindles. These signals are then compared with respect to one another. The most significant signal at any instant in time is then produced as an output signal representing the most significant eccentricity signal.
