초경드릴을 이용한 탄소섬유 에폭시 복합재료의 드릴링 특성에 있어 선단각의 영향
Effects of the Point Angle on Drilling Characteristics Carbon Fiber Epoxy Composite Materials Using WC-drill Drilling
초록
The drilling experiment of carbon fiber epoxy composite material with WC-drill has been done under the various cutting condition in order to minimize the problems occured in the material when being drilled. It has been comfirmed by a frequencyanalysis of the cutting force signals that the variation of cutting force resulted from the periodic variation of the angle between the rotating drill and the stacking angle of the carbon fiber. The drilling experiment has been done with several drills having different point angles and the drilling characteristics, like the effects such that change in the point angle influences the cutting force and the external surface condition, was evaluated.
