OPTIMIZATION OF MACHINING PARAMETERS IN MILLING OF Ti-6Al-4V ALLOY USING TAGUCHI METHOD

This paper presents optimizing and effect of machining parameters on the cutting forces and surface roughness during face milling of Ti-6Al-4V alloy with carbide tools under dry conditions. Experimental setup was determined by using Taguchi design method. The optimum machining parameter combination was acquired by using signal-to-noise (S/N) ratio analysis. According to experimental results, resultant cutting forces and surface roughness increased with an increase in feed rate, whereas decreased with increase in cutting speed. Optimum machining conditions for the both resultant cutting forces (FR) and surface roughness (Ra) were obtained at cutting speed of 180 m/min and feed rate of 250 mm/min.
