Initially, the angular position of a tracing pin is calibrated. The dimensions and positions of the tracing pin are determined therefrom and stored. Subsequently, all positions required for the measurement of a workpiece by means of a tracing pin in a CNC process and the angular positions thereof are determined by moving the workpiece using a joystick control unit and are stored in a list, whereupon all angular positions from said list are automatically calibrated. Said automatic calibration occurs using the data of one calibrated angular position together with a geometric model of the rotating-pivoting hinge. The calibrating data thus obtained is stored. The CNC process required for measurement of the workpiece can be carried out with the aid of the list and the determined calibrated data, whereby measurements with co-ordinate measuring devices with rotating-pivoting hinges are highly automated. |
