Abstract
A method for measuring errors in the linear feed shafts of a multi-spindle machine tool having two or more rotating feed shafts in addition to three linear feed shafts, wherein: at least first through third reflecting mirrors are attached to a table of the machine tool; a laser length-measuring machine is attached to the tip of a principal shaft of the machine tool; the linear feed shafts are driven, and the laser length-measuring machine is moved to prescribed measuring points; the two or more rotating feed shafts are driven at each of the measuring points; the coordinates at each measuring point are calculated by measuring the distances between the first through third reflecting mirrors and the laser length-measuring machine; and errors in the linear feed shafts of the machine tool are obtained by comparing the machine coordinates of the machine tool.
