ABSTRACT:
A duplicating arrangement is provided for duplicating a workpiece. Data of the workpiece are obtained by scanning of a model, the data are then digitized and stored. The data which is obtained are transformed into NC sets. A relative tool correction consideration is performed in determining the control signals for the drives of the NC machine. The relative tool correction accounts for the generally variable dimensions of the scanning ball used in the scanning of the model and of the radius of the milling tool in the production of the workpiece. A correction movement is superposed on the relative movement between the milling tool and the workpiece if a collision consideration determines that contour surface parts are within the projection surface of the milling tool.
