“…Davim and Reis discussed a new comprehensive approach for selecting cutting parameters in order to achieve damage-free drilling based on a combination of Taguchi's techniques and on the analysis of variance (15) (16) . One of the other approaches is to apply a vibration-assisted drilling technique that has been presented by Wang et al (17) (18) . All of the above studies have focused attention on the reduction of the thrust force during the drilling processes.…”

For generating holes on carbon fiber reinforced plastic (CFRP) composites, drilling is one of the most commonly applied processes. However, machining defects caused by delamination occur frequently during this kind of process. To realize defect-free drilling of CFRP composites, we propose to apply feedback control based on thrust force, because the degree of thrust force is directly related to the occurrence of delamination. In this study, we have developed a machining system which can be operated at a predetermined cutting force by changing the feed rate based on cutting force signals measured by a piezoelectric cutting dynamometer, and the basic performances of the developed system have been confirmed through evaluation tests. In addition, drilling tests with the developed system were carried out, in order to consider the possibility of defect-free drilling of CFRP composites with feedback control based on cutting force. In the drilling tests, we used a conventional twist drill, and the work-piece was a quasi-isotropic laminate composite, which is a stack of unidirectional plies consisting of high-strength carbon fibers T800S and high-toughness matrix resin 3900-2b. We have confirmed, under specific conditions through drilling tests, that the feedback control process can machine through-holes without causing significant machining defects on CFRP composites.

“…Drilling process becomes an intermittent cutting by low-frequency vibration with enough amplitude. Zhang et al (9) and Wang (10) and Sakurai (11) investigated the machining force in vibration drilling. Jin (12) et al also examined the step vibration drilling for difficult to cut materials and showed the capability of the step vibration drilling.…”

Dry drilling of composite/metallic stacks for aircraft components is extremely difficult to keep sufficient hole quality and efficiency of drilling process. Problems of the dry drilling of those kinds of stacks are chip ejection, chip formation and high temperature especially for titanium alloy. To clear these problems, low-frequency vibration (10-50 Hz) drilling is proposed in this study. Controlled sinusoidal vibration was given in drill axis direction with constant feed motion. The relationship between vibration conditions, such as vibration amplitude, frequency and drill feed rate, and chip formation and drilling temperature were investigated. As a result, low-frequency vibration drilling can control chip formation to reduce chip jamming and can reduce drilling temperature. Temperature measured at the cap burr decreased by 300 degrees C or more when low-frequency vibration was applied compared with the conventional drilling. Also the wear rate of the drill is decreased when the vibration is applied.
