CFRJP has recently been drawing an attention as aerospace components, but machining of such composite materials with coolant causes problems when disposing and separating cutting powder dusts from coolant. Also, the waste has negative influence on the environment. In contrast, the dusts produced during dry machining of CFRP bring harmful effects on the human body. Besides, the cutting tools are exposed to high cutting temperatures resulting in a short tool life. In order to overcome such problems, a chip vacuum system has been developed. The system enables to vacuum the harmful dusts when dry machining of CFRP, and also a longer tool life can be expected by the cooling effect.
