The performance of VHSD (above 15 000 rpm) of CFRPs was investigated by the authors for high productivity axial feeds of 8 and 12 m/min (equivalent to drilling time of 60 and 40 ms, respectively, for an 8 mm thick plate). Figure 13.7 shows that for both axial feeds,the thrust forces decreases with higher rotational speeds due to the decrease in the feed per tooth.
