Delamination is a dramatic problem associated with drilling fibre-reinforced composite materials (FRCMs), which, in addition to reducing the structural integrity of the material, also results in poor assembly tolerance and has the potential for long-term performance deterioration. The key to solving
Measurements of the chip flow angle and of the chip length ratios (which afford estimates of the normal shear plane angle) along with calculations of the change of rake angle along the lips of spade drills reveal that removal by the kips in spade drilling is quasi.orthogonal. This, coupled with the
