    Abstract:

    In this paperꎬ orthogonal cutting was used to investigate material cutting and surface forming process
    of CFRP composite materials under small cutting parameters. An intensive discussion was given about several key
    problems when machining CFRP for high precisionꎬ such as fiber orientationꎬ cutting parameter range and cutting
    edge radius. Experimental results indicate that CFRP behaves with notable anisotropy and cutting direction affects cut ̄
    ting process greatly. 0° and 135°cutting directions result low cutting force levelꎬ and 0° and 90° cutting directions
    generate improved surface quality. As to precise cutting of CFRPꎬ to reduce cutting force and improve surface qualityꎬ
    the 0° fiber orientation is advisedꎬ cutting speed is supposed to exceed 200 m/ minꎬ cutting edge radius should be
    sharpꎬ and cutting depth should exceed cutting edge radius.
