Abstract: In the program control of a robot intended for painting vehicles and in order to facilitate finding the numerous coating parameters stored in a robot movement program, coordination between the process parameter change point and the relevant coating parameters is to be obtained. To this end, and to establish a path of movement, an individual address is associated with each process parameter change point and, based upon the movement program, a separate parameter file is employed in which the relevant coating parameters are associated with the individual addresses. According to the subject method, the configuration of the workpiece to be coated is shown upon a display screen and, by utilizing the movement program, the selected process parameter change points are indicated visibly upon the workpiece shown.
