Orbital Drilling of small (<10mm diameter) holes, standardly spaced with aluminium material in the stack

There are two lines of research proposed in this call, both related to the development of orbital drilling. The first is to introduce residual stress when drilling in aluminium, this is seen as the main reason orbital drilling is not more widely used in the aerospace industry. The second is to enable drilling of smaller holes positioned closer together (a limitation with existing machines/methods). For the full topic description see the Call Text Document (Annex of Workplan) published with this call.
