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 different results depending the fibre orientation. Recently, a process-independent model describing engagement conditions in oblique cutting of has been developed, introducing spatial angles θ0 φ0. Since milling drilling are complex, analogy experiments conducted turning with variation setting κrand inclination λs. In this study, process forces surface roughness were measured as function complete range angle θ.
