Article: Experimental study of coated carbide tools behaviour: application for Ti-5-5-5-3 turning Journal: International Journal of Machining and Machinability of Materials (IJMMM) 2011 Vol.9 No.3/4 pp.233 - 248 Abstract: The goal of this paper is to study the relation between the input data (conditions and geometry of cut) and answers (wear of tool, forces and cutting temperatures) when machining the Ti-5-5-5-3 alloy treated. This study has shown that the cutting process is different and that the slip forces are preponderates. Compared with other materials, the specific cutting pressure is higher and does not vary according to the cutting speed but depend on feed rate. Moreover, both edge preparation and feed rate have an influence on cutting force direction. Besides, cutting temperatures are high and almost similar to those provided by high speed machining with low cutting speed. Finally, we have shown that failure modes are different from those obtained when machining other titanium alloys. Built-up edge is the most deteriorating phenomenon and no flank wear was met in our study context. Inderscience Publishers - linking academia, business and industry through research
