Abstract

Carbon fiber reinforced plastic composites are being increasingly used for more applications. The evaluation of hole-drilling in these composites remains a difficult and unsolved problem. The drilling process for multi-material composites is quite different than those for their more conventional metal counterparts. In the research reported here, the drilling ability and durability of drills used for drilling carbon fiber reinforced plastic composites, made with a diamond layer was deposited by chemical vapor deposition are evaluated with different r/min. Spindle speed was fixed reasoning based in abundant previous works. A thermal camera and related techniques were used to evaluate chip removal, temperature measurement inside the hole, associated thermal damage during the drilling operation, in an effort to ascertain optimal drilling conditions. Currently, chemical vapor deposition diamond drills appear to produce better holes at lower r/min.
