The correct choice of the drill and the cutting parameters is crucial in carbon fibre reinforced plastics (CFRPs) drilling quality. In this work, the influence of three distinct drill geometries and cutting parameters (feed rate and spindle speed) in the delamination was assessed through two delamination factors. A non-destructive method, based on processed images analyses of the drilled surfaces, was used to measure the delaminated area and the maximum diameter of damage zone. The best results were obtained with a SPUR drill. With this, the higher rate of production, without the occurrence of delamination, was obtained with a feed rate of 2025 mm/min and a spindle speed of 6750 rpm. (c) 2012 Elsevier Ltd.
