Recent changes in the aircraft production process forces us, as a supplier of aircraft assembly equipment, to design innovative and modular manufacturing equipment that complies with modern specifications. This is especially true of composite manufacturing processes in combination with new materials that are now under development. In some applications, the potential for optimizing existing manufacturing processes (e.g. Prepreg-technology) as related to quality improvements and cost reduction has reached their limit. Using optimized production processes like preforming and resin infusion could allow one to achieve considerable benefits. This paper describes the latest development of a robot cell for dry fiber placement. Our customer's application required a completely new type of end-effector and an extension of the proven high accuracy robot positioning system.

Manual drilling in carbon fiber and mixed material structures is a labor and cost intensive process. Therefore, the aircraft manufacturers are constantly investigating flexible and cost-effective automation solutions to improve their production solutions. These objectives inspire us, as a supplier of aircraft assembly equipment, to develop robot and end-effector technologies to fulfill the customer's requirement for a highly accurate, robotic based drilling system for varying aerospace applications. This paper presents an innovative robot cell for drilling different aircraft parts consisting of CFRP and aluminum. The required absolute positioning accuracy is reached by using a proprietary compensation package for the robot that was developed by BROETJE-Automation. The new robot cell is based on a scalable system configuration which provides for the future extension of the work envelope and the integration of automated blind fastening.
