作者娄帅伟（2019）在《基于碳纤维复合材料各向异性的磨削特性研究》一文中研究指出：碳纤维复合材料由于其比模量高、比强度大等优点在航空航天以及军工领域得到了广泛的应用。随着上述领域产品对表面精度的要求不断提高以及零件的结构形状日益复杂,对碳纤维复合材料的加工技术提出了越来越高的要求。本文从分析碳纤维复合材料的材料去除机理入手,基于材料的各向异性用金刚石砂轮对碳纤维复合材料进行了磨削试验,并对磨削过程中的磨削力和磨削热进行实时测量,而后对加工表面的表面形貌和粗糙度进行检测,分析了磨削纤维角和磨削参数对磨削力、磨削热以及加工形貌和粗糙度的影响规律。主要的研究工作如下:(1)通过碳纤维复合材料的单颗粒磨削试验得到了材料在不同磨削纤维角下的材料去除机理。在顺纤维磨削加工关系中,主要以界面剥离为主,形成由长纤维纵向铺成的沟痕形貌,并形成以纤维空隙、树脂耕犁和纤维断续损伤等为主的缺陷形式;在垂直纤维磨削加工关系中,主要以剪切破坏为主,形成由剪切断口组成的沟痕形貌,并在磨粒的推挤作用下在沟痕中有微裂纹产生;在顺纤维磨削加工关系中,则主要以剪切和挤压共同作用形成,产生较为平整的磨痕形貌;在逆纤维磨削加工关系中,主要以弯曲破坏为主,在前刀面的作用下,会有纤维拔出或裂隙等缺陷产生。(2)利用加工中心用金刚石砂轮对碳纤维复合材料进行干磨削试验,并对磨削力进行了实时测量,研究了磨削纤维角和磨削参数对磨削力的影响规律。发现在整个磨削加工过程中切深抗力大于主切削力;在磨削参数保持不变的条件下,不同磨削纤维角下的磨削力大小关系为:135°>45°>90°>0°;随着磨削深度的增大,主磨削力和切深抗力均呈增大趋势,且随着磨削深度的增大,各个碳纤维复合材料各向异性程度有增强的趋势;随着主轴转速的增大,磨削力逐渐减小,且四种磨削纤维角中0°时磨削力受速度影响较小。(3)在磨削加工的同时对磨削温度进行了测量,在碳纤维复合材料磨削加工中磨削热与金属加工相比处于较低水平,且随着磨削纤维角的变化也表现出明显的各向异性。随着主轴转速的增大,磨削温度逐渐升高;随着磨削深度的增大四种磨削纤维角下的温度都逐渐升高。(4)对磨削加工后的表面形貌进行了观察和粗糙度的检测,分析了不同磨削纤维角和磨削参数对磨削加工表面形貌和表面粗糙度的影响规律。发现不同的磨削纤维角产生不同的表面形貌和加工缺陷;随着磨削深度的增加,表面质量逐渐降低,加工缺陷数量有所增加;随着主轴转速的增大,表面质量有所改善,在四种磨削纤维角中0°时受速度影响最小。
