Effects of cutting parameters on delamination during drilling of Polyphthalamide (PPA) Matrix Composite Material with 30% Glass Fiber Reinforcement

Languages of publication
The drilling of glass fiber reinforced plastics (GFRP) often results in damage around the drilled hole. The drilling of such composite material may generate delamination of drilled holes on workpiece. The aim of this research is to investigate the influence of the drilling parameters, such as cutting speed, feed rate and differences in cutting materials on delamination produced while drilling GFRP composite. The experimental results indicate that the feed rate is the most significant factor, followed by spindle speed and cutting tool material. The best results were obtained at lower feed rates and higher spindle speeds when using Carbide drill.
