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 θ0 and φ0 . Since the engagement conditions of milling and drilling are complex, analogy experiments are conducted in turning with variation of the setting κr and inclination angles λs . In this study, process forces and surface roughness were measured as a function of the complete range of fibre cutting angle θ.
