Wheels turning center measurement method and the grinding wheel turning center measuring device

摘要

PROBLEM TO BE SOLVED: To provide a method and device for measuring a revolution center of a grinding stone capable of measuring, with a high degree of accuracy, a position of an actual rotation center point in relation to a position of a grinding stone reference point of a grinding wheel.;SOLUTION: The grinding wheel 42 is positioned at first to fourth revolution angle positions to determine positional relationships between four plate reference points P0 and a controlled revolution center Cc. Then, from the four positional relationships, and a known dimensions of a master plate 24, and the like, a relationship between a grinding stone reference point Pg of the grinding wheel 42 and an actual revolution center point Cr is geometrically calculated. According to this method, improved is a shape accuracy of a grinding stone in truing for shaping an R form of the grinding wheel 42 by revolving a grinding stone table 40.;COPYRIGHT: (C)2012,JPO&INPIT
