EXAMINATION OF THE EFFECTS ON THE HOT MACHINING OF TI-6AL-4V WITH THE FINITE ELEMENT METHOD

Abstract

Heat assisted machining, known as hot machining, is an alternative machining method to increase the machinability of hard-to-cut metals and alloys. This study includes the investigation of cutting forces in hot working of Ti-6Al-4V alloy, which is widely used in the industry, by finite element method. Processing experiments were performed with ThirdWave AdvantEdge, the finite element analysis software. Analyzes were determined at constant depth of cut, cutting speed (V), feed rate (f), and temperature parameters were determined as three levels. Experiment list was created with Taguchi L9 orthogonal array. Cutting forces values were recorded according to the L9 experimental design. According to the results of the numerical analysis, it was observed that the cutting forces decreased when the room temperature conditions were compared with the hot machining conditions. The lowest cutting force value was measured in numerical analyzes carried out at 600°C hot machining conditions.
