Streszczenie

Dobre właściwości stopu tytanu Ti-6Al-4V decydują o jego szerokim zastosowaniu, lecz jednocześnie wpływają na trudnoobrabialność. Jednym z czynników, który wpływa na obrabialność stopów metali jest współczynnik tarcia, którego wartość może być obniżana dzięki zastosowaniu różnych metod chłodzenia i smarowania. W niniejszej pracy przeanalizowano wpływ wartości współczynnika tarcia na przebieg procesu toczenia stopu Ti-6Al-4V, na podstawie symulacji MES przeprowadzonych w programie DEFRORM 2D/3D. Pokazano, iż współczynnik tarcia ma wpływ na wartość siły skrawania i siły odporowej. Uwidoczniono również istotny wpływ wartości współczynnika tarcia na współczynnik spęczenia wióra.

Abstract

The good properties of Ti-6Al-4V titanium alloy make it widely used, but at the same time, make it difficult to machine. One of the factors which influence the machinability of metal alloys is coefficient of friction, which can be lowered by multiple cooling and lubricating methods. In the present work the influence of coefficient of friction on the turning process of Ti6Al-4V was analyzed based on the FEM simulations conducted in DEFORM 2D/3D software. It was proven that the coefficient of friction influenced the cutting force and thrust force. It was also shown that the coefficient of friction had a significant impact on the chip compression ratio.
