Automated Sanding of Aircraft Coatings

A cost effective and low risk automated sanding system that utilizes an innovative and extensible system architecture for removal of aircraft coatings is proposed. Elements of the Integrated Product/Process Development and robust design methodology will be applied in a systematic and exhaustive qualitative and quantitative assessment to identify the technologies, architecture and design concept that provides the best solution to meet the automated sanding requirements. The basic elements of this system are: • multi-spectral sensors to determine coating thickness on various substrates, • industrial robot with precision movement control, • intelligent control algorithm, • sanding subsystem having interchangeable sanding tools, • coating containment system. The system will be cost effective and low risk by taking advantage of many commercial off-the-shelf (COTS) components A proprietary control algorithm will provide communication and control between the several subsystems. Measurements of coating thickness and sanding logic will be demonstrated on test coupons fabricated from coatings and substrates representative of the subject aircraft.
