Development of data-driven PHM solutions for robot hemming in automotive production lines

Robotic roller hemming is currently one of the most used solution for joining metal sheets in automotive industry, especially those production lines which need to favor flexibility with respect raw productivity and mostly employed assemble car doors. Hemming a fairly delicate process since it does not only suffice technical requirement – join two panels together but also an aesthetical one, joint are integral part vehicle design as such important selling point. An unpredicted rupture or advanced degradation condition system would lead significant loss quality final product sudden stoppage line. The development PHM devices hence provide advantage, if designed work both new legacy equipment. In this paper, we results preliminary analysis framework robotic studied without having access PLC data, data-driven methodology detailed applied case increasing wear head finger roll. Results from different prognostics routines presented compared.
