Robotised Geometric Inspection of Thin-Walled Aerospace Casings

Abstract

This paper deals with the development of dimensional control technology for the production of ADT (accessory drive train) gearbox housing. The project included the development of a robotic geometry inspection station for thin-walled aerospace casings. Laser profilometers from two brands, Cognex and Keyence, were used to measure. A proprietary software solution for arc measurements is presented. The obtained solutions were compared and verified in accordance with the requirements of the manufacturer Pratt and Whitney Rzeszów S.A. The results of the work indicated that correct solutions were obtained with a very large reduction in control time. In addition, the measurement is fully automated and transferable to the company’s electronic systems.

Application of a 3D Scanner in Robotic Measurement of Aviation Components

“…In non-contact measurements, laser heads [24] or optical scanners [15] are used. Optical scanners are mounted on stands [4,25] or on robot arms [31]. Contact devices are not sensitive to: dust, glare and lighting, but are slow compared to the number of measurements collected using non-contact methods.…”
