“…with − → F : the cutting forces (N) and − → v : the velocity (m/s). According to some observations made by [8], Deshayes and coworkers note a better definition of the cutting parameters in using dynamometer platform allowing to exclude cinematic effects of lathe [9]. The specific cutting forces and consequently spindle power remain stable over a range of cutting speed contrary to the power measurements.…”

“…where f z is the feed rate (mm/tooth), a p is the axial depth (mm), r is tool radius (mm), and θ is the insert position ( • C) However, this method does not allow to define the specific pressure for each insert position. For this study, the chip thickness will be defined with the following relation (9).…”

International audienceThe Ti-1023 beta alloy titanium is used in aeronautics for the production of structure parts such as landing gear and as most of titanium alloys its machinability is poor explained by its physical and mechanical properties. This work presents the machinability results carried out for Ti-1023 milling in using toroidal tool. The aim of this research is the understanding of tool wear mechanisms and to establish the relation between cutting conditions, milling tool geometry, and tool life. A section is also devoted to the chip analysis. The wear modes are also analyzed and defined for different cutting tool geometries where several steps occur. This study is focus on material removal rate, tool life, and volume

“…Saglam et al (2007) have studied the effect of geometry of cut and the cutting conditions on forces and cutting temperatures. Deshayes (2007) have analysed the evolution of cutting force and wear of inserts with chip breaker. Other authors oriented their efforts toward the influence of the cutting edge geometry on cutting forces for machining conventional materials as aluminium and steel (Fang and Wang, 2005;Yen et al, 2004).…”

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.
