The paper presents the earliest results of a research collaboration between the aircrafts company Piaggio Aero Industries (PAI) and the PMARLab Robotics Research Group of the University of Genova, aimed at the development of a parallel-hybrid machine for the machining of body panels of the aircraft P180. Most of the manufacturing of the body panels of this small airplane, today, is performed manually and by chemical milling, with high process costs. A task-oriented machine able to perform all these operations (without moving the parts between different working stations and avoiding specific preparation, e.g. peeling for chemical etching) could remarkably reduce costs and overall process time, improving quality and accuracy of the machined components. Moreover, the need for adjustments in the subsequent assembly steps of the assembly process (e.g. correction of holes during riveting) would be eliminated or dramatically reduced. The panels have complex curvatures and are very different in size. Their manufacturing involves few millimeters depth high-speed milling, contouring, deburring, holing. The technological processes to be performed have different stiffness, accuracy, force and surface finishing requirements; this makes the design of one machine for all processes complex. The finally proposed architecture is hybrid, composed of a 2-dof cartesian-parallel unit carrying an agile 4-dof hybrid-parallel unit supporting the spindle.
