In order to explore the wear mechanism of single cBN-WC-10Co fiber cutter in machining of Ti-6Al-4V alloy, this study performs scratch tests, and develops a theoretical model based on the evaluation of cutting performance. The scratch and wear morphologies of the fiber cutter are analyzed by an optical profilometer and scanning electron microscopy (SEM). The wear behavior of the fiber cutter is evaluated comprehensively in terms of cutting forces, the wear morphology of fiber and the profile of scratches with respect to cutting passes. The pres...
