This paper aims to establish a 3D evaluation method for cutting surface topography of C/C composites.The cutting surface is measured by Talyscan 150,using 3D non-contact measurement.By evaluating2D and 3D roughness of C/C composite and Duralumin,the 2D evaluation method of the cutting surfacetopography of C/C composite loses a lot of information,and the characteristics of the surface topographyof C/C composite can be comprehensively and authentically evaluated only by the 3D evaluation method.Furthermore,3D amplitude and spatial parameters are adopted to evaluate the surface and the resultsshow that:the topography of the C/C composite is anisotropy and there are no obvious feeding texturesbut abrupt peaks and valleys on surface of the C/C composite,which indicates that the machining mechanismis different from that of the metal.In conclusion,The C/C composite surface is evaluated using a3D evaluation method,the roughness error is small,and the unique topography characteristics can be authenticallyevaluated.

Fuerthermore, 3D amplitude and spatial parameters are to evaluate the surface and the resultsshow that: the topography of the C / C composite is anisotropy and there are no obvious feeding texturesbut abrupt peaks and valleys on surface of the C / C composite, which indicates that the machining mechanism is different from that of the metal. In conclusion, The C / C composite surface is evaluated using a3D evaluation method, the roughness error is small, and the unique topography characteristics can be au thenticallyevaluated.
