摘要

碳纤维增强聚合物（CFRP）因其重量轻、机械性能优异而得到广泛应用。然而，在单向 CFRP 上使用相同的加工参数会因纤维取向的不同而导致不同的结果。最近，我们建立了一个与加工无关的模型，该模型描述了单向 CFRP 斜切时的啮合条件，并引入了空间角 θ0 和 φ0。由于铣削和钻孔的啮合条件比较复杂，因此在车削中进行了类比实验，并改变了设定值κ和倾斜角λs。在这项研究中，测量了加工力和表面粗糙度与整个纤维切削角 θ 范围的函数关系。

Influence of spatial engagement angles on machining forces and surface roughness in turning of unidirectional CFRP

Carbon fibre-reinforced polymer (CFRP) is being widely used due to its low specific weight and outstanding mechanical properties. However, using identical machining parameters on unidirectional CFRP can lead to different results depending on the fibre orientation.

Recently, a process-independent model describing the engagement conditions in oblique cutting of unidirectional CFRP has been developed, introducing the spatial angles $θ_{0}$ and $φ_{0}$ . Since the engagement conditions of milling and drilling are complex, analogy experiments are conducted in turning with variation of the setting $κ_{r}$ and inclination angles $λ_{s}$ . In this study, process forces and surface roughness were measured as a function of the complete range of fibre cutting angle $θ$ .
