Summary:

The present paper has investigated the effect of nose radius (rz-mm) on cutting parameters during the machining process in a face milling for titanium (Ti-6Al-4V) alloy. The cutting machining tests were performed with various nose radiuses (rz-mm) while the cutting speed (vc-m/ min), feed rate (f-mm/tooth) and depth of cut (d-mm) were remained constant. The equivalent plastic strain (PEEQ) was measured by using the development two-dimensional orthogonal cutting process of finite-element modeling through “ABAQUS/EXPLICIT software”. The results led to conclusions that the equivalent plastic strain (PEEQ) was increased and improved a good surface roughness finishing when increasing nose radius (rz-mm) during the machining process.
