Abstract:
1. A method for compensating static positioning errors in guiding a movement of a movable machine element of an industrial processing machine, with a predetermined standard parameter for generating reference variables for one or several drives for controlling the machine element in a predetermined workspace, comprising the steps of: providing a compensation table with compensation values for a predetermined number of different operating points in the workspace; setting the compensation values to a value of zero, said compensation values to be added to generated reference variables, determining a suitable compensation value for the reference variables located between the predetermined operating points by interpolating between adjacent compensation values of the compensation table, determining positioning errors occurring during machining and adjusting the compensation values of the compensation table using the determined positioning errors by either replacing an existing associated compensation value with a new compensation value corresponding to the additional positioning error, if the positioning error coincides with a predetermined operating point, or by correcting the points of the compensation table adjacent to the corresponding measurement point at least partially according to the determined positioning error.
