Method for checking the positioning accuracy of a machine part that is displaceable with respect to at least one axis by means of a drive and a controller

Abstract

A method which allows an operator to quickly form a clear picture with regard to the positioning accuracy of a machine part that is displaceable along an axis by means a drive controlled by a controller includes specifying with the controller nominal position values of the machine part in relation to a single axis, wherein the nominal position values are defined by a sine function; displacing the machine part with respect to the single axis in accordance with the nominal position values; determining with a measuring device actual position values of the machine part in relation to the single axis; and visualizing the actual position values of the machine part in relation to the single axis graphically in a circular representation.
