Abstract:
A method for determining and optimizing an operating accuracy of a device using a position measuring system, comprising the steps of:sampling path information data on designated axes over a predetermined measuring interval;storing the path information data in a numerical control unit;processing the path information data to determine the operating accuracy, the step of processing including the steps of:determining an actively described actual path of the designated axes corresponding to a contour of the path information data;determining an active actual-value vector as a function of the path information data;comparing the actively described actual path to a profile of a corresponding setpoint path;determining a setpoint-value vector having a first angle, the first angle being equal to a second angle of the active actual-value vector, the setpoint-value vector establishing a geometric relation between the actively described actual path and the corresponding setpoint path;determining a contour deviation at a predetermined path point as a function of a distance between the actual-value vector and the setpoint-value vector at the predetermined path point; andadjusting compensation parameters to minimize the contour deviation.
