Abstract

The invention relates to a method for machining flat workpieces in a double-sided machining tool, which has an upper and a lower work disk, wherein at least one of the work disks is rotatingly driven and the work disks each have an annular work surface, wherein the work surfaces amongst themselves limit an also annular work gap, in which at least one carrier is located, which guides at least one workpiece in the work gap, so that the at least one workpiece is machined in a double-sided manner between the work surfaces. The distance between the work disks is measured at at least two radially spaced measurement locations of the work gap and in that, from the measured distances, a distance between the work disks is determined at a location of the work gap representing the thickness of the at least one workpiece machined in the work gap.
