Drilling carbon fiber reinforced plastics (CFRP) is the most common machining operation during the assembly process in the aerospace and automotive industries. Due to the inhomogeneity of the CFRP, different kind of errors occurs comparing the drilling of traditional materials, the biggest problem being the delamination. The aim of this paper is to investigate the influence of the feed rate and spindle speed on delamination resulted while drilling CFRP materials. A plan of experiments based on Taguchi Method was made considering a combination of three different values for feed rate and three different values for spindle speed. Analysis of variance (ANOVA) was used to analyze the experiments results and to determine the optimal cutting parameters.
