RESEARCH ON SELECTION OF GRINDING CONDITIONS FOR MACHINING TITANIUM ALLOY Ti6AL4V

Abstract

Titanium Ti-6Al-4V alloy is a widely used material in industry, but it is also an extremely difficult alloy to work due to its high adhesion. numbers with reasonable machining conditions are still difficult. In this paper, the Taguchi method has been applied to determine the optimal grinding conditions according to the criterion of minimum surface roughness. The experimental plan is based on the L9 orthogonal array with the input variables being rock velocity, rock grain, and lubricating type. The comparison between the calculated and experimental results shows that they are quite consistent with each other, allowing to confirm the reliability of the experimental model.
