Abstract:
1. A dynamic alignment monitoring system for an on-vehicle disk brake lathe system having an alignment mechanism for reducing misalignment between a lathe axis and a hub axis about which a brake disk rotates, the dynamic alignment monitoring system comprising: an angular rate sensor for providing an angular rate signal responsive on a time-dependent basis to angular motion resulting from the misalignment; a tachometer providing a tachometer signal responsive to the speed of rotation of the lathe; an alignment signal processing routine that operates on the signals generated by said angular rate sensor and said tachometer to provide a time-dependent output; a scaling routine for processing the angular rate signal so as to allow said alignment signal processing routine to provide a derived lateral runout (LRO) value for the brake disk which would result from machining under the current misalignment condition; a display for presenting a representation of the derived LRO value in a time-dependent manner; and an alignment control routine for operating the alignment mechanism to reduce the misalignment in response to the time-dependent output of said alignment signal processing routine,
