External Realtime Position and Orientation Control Circuit for Path Accuracy Improvement of Industrial Robots

EtherCAT® Bridge ECX-EC connects PC and Robot Control

At the research center CFK NORD the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM carries out solutions for industrial robots accuracy improvement to use it for machining applications of large structures in aircraft industry in the future.

Industrial robots with six axis have advantages in this application range over the existing large chipping machine tools in gantry design because machine tools are relatively expensive, heavy and inflexible. Indeed industrial robots equipped with a high frequency spindle are in principle suitable for CFK chipping, but they do not achieve the required path accuracy for aircraft industry.
