Simultaneous machining of aerospace structural materials using poly-drills
… among all the machining processes as millions of holes are required to produce riveted and bolted joints in the assembly operation of the aircraft's structures. The major challenges which arise from the drilling of these alloys are characterized by the low hole quality, which might initiate cracks …

Annular Beam Shaping And Optical Trepanning
… to approximately the required diameter of the hole, exposing the material to one or a series of laser pulses at the same spot to melt and vaporize the material. Drilling by trepanning involves cutting a hole by rotating a laser beam with an optical element or an x–y galvo-scanner. Optical …

An analytical tool wear model for drilling of continuous fibre reinforced composites
… and good corrosion resistance. Drilling holes to facilitate the mechanical joining of CFRP to other, metallic components is a key operation during aircraft manufacture and high rates of tool wear are experienced in commercial practice. Unmonitored tool wear can lead to increased cutting …
