Abstract
A method for detecting the coordinate position of the grinding point of a grinding wheel supported on a swiveling table comprises the steps of: rotating drivably the swiveling table through a specified angle from a start position so as to arrive at a first turning position; measuring a first displacement of the grinding point of the grinding wheel from the start position by displacement measuring means; rotating the swiveling table through the specified angle from the first turning position so as to arrive at a second turning position; measuring a second displacement of the grinding point of the griding wheel from the first turning position by the displacement measuring means; and calculating the position of the grinding wheel with respect to the swivel axis of swiveling table according to the first and the second displacement and the specified angle.
