Abstract

A method for machining a scale of a position-measuring system is provided for such a scale having, on a first surface, a measuring graduation and, on a second surface, is attachable to a carrier body. The first and second surfaces are bounded respectively by first and second edges in a region of a lateral peripheral side edge. The scale is machined to produce a defined outer contour of the scale such that a raised ridge of material is formed at each of the first and second edges. The scale is machined differently at the first edge than at the second edge in such a manner that a dimension of the raised ridge of material at the first edge perpendicular to the first surface is smaller than a dimension of the raised ridge of material at the second edge perpendicular to the second surface.
