To meet the increasing application requirements of stainless steel fibers with rough surface morphology, a self-made multi-tooth tool which can bifurcate chip during the cutting process was utilized to manufacture stainless steel fibers. The novel cutting method can achieve efficient processing of continuous stainless steel fibers with complex surface morphology. The influence of cutting parameters (back engagement ap and feed rate f ) on forming process of fibers’ surface morphology was studied. The cutting experiments were carried out under the condition of selected tool and fixed workpiece rotating speed. The results show that: the surface morphology of stainless steel fiber is simultaneously effected by ap,and feed rate f .Between them, ap has more significant effect on it. In order to obtain stainless steel continuous fibers with coarse surface morphology, the optimum cutting parameters were recommended as follows: ap∈(0.1-0.2) mm, f ∈(0.1 -0.17) mm/r.
