摘　　要：目前针对碳纤维复合材料主要采用二维轮廓算术平均偏差Ra对切口表面质量进行评价。而由于CFRP具有不同于金属材料各向异性的特性,Ra不能充分体现表面的微观形貌,从而无法准确表征加工切口表面质量。通过开展碳纤维复合材料铣削加工试验,分析了不同加工参数下碳纤维复合材料加工切口表面三维粗糙度(Sa、Sq、Sz、Ssk和Sku)、纤维崩缺深度Sv、撕裂宽度w与撕裂长度l,从而揭示了铣削参数对碳纤维复合材料加工切口表面质量的影响规律。Currently,for carbon fiber composite materials,the arithmetic mean deviation Ra of the two-dimensional profile is mainly used to evaluate the surface quality of the incision.However,since CFRP has different anisotropy properties than metal materials,Ra cannot fully reflect the microscopic topography of the surface,so it cannot accurately characterize the surface quality of the machining incision.By carrying out the milling processing test of carbon fiber composite materials,the three-dimensional roughness(Sa,Sq,Sz,Ssk and Sku),fiber chipping depth(Sv),tear width(w)and tear length(l)of the cut surface of carbon fiber composites under different machining parameters were analyzed,thereby revealing the influence of milling parameters on the surface quality of carbon fiber composites machined cuts.
