3D evaluation method of cutting surface topography for C/Ph composites was established.The cutting surface was measured by Talyscan 150,using 3D non-contact measurement.Through the results of 2D and 3D roughness evaluating for C/Ph composite and Duralumin,the 2D evaluation method of the cutting surface topography of C/Ph composite loses a lot of information,the characteristics of the surface topography of C/Ph composite can be comprehensively and authentically evaluated only by 3D evaluation method.Furthermore,3D amplitude and spatial parameters were adopted to evaluate the surface.The results show that: the topography of the C/Ph composite is anisotropic,there are more valleys in the machined surface of C/Ph than that of duralumin,and there are not obvious feeding textures for C/Ph,which indicates the machining mechanism is different from the metal.In conclusion,the topography of the C/Ph composite cutting surface is anisotropic;the cutting surface of C/Ph composite needs 3D evaluation method.

Hotter, 3D amplitude and spatial parameters were to evaluate the surface. The results show that: the topography of the C / Ph composite is anisotropic, there are more valleys in the machined surface of C / Ph than that of duralumin, and there are not obvious feeding textures for C / Ph, which indicates that the machining mechanism is different from the metal. In conclusion, the topography of the C / Ph composite cutting surface is anisotropic; the cutting surface of C / Ph composite needs 3D evaluatio n method.
