Experiments of Ti6Al4V manufactured by low-speed wire cut electrical discharge machining and electrical parameters optimization

Abstract Titanium alloy Ti6Al4V is widely used in aerospace, shipbuilding, petrochemical, and other industrial fields. Low-speed wire-cut electrical discharge machining (LS-WEDM) has the advantage of high accuracy. However, there are few research studies on comprehensive effects parameters TC4 (Ti6Al4V) made by LS-WEDM surface. This paper focuses titanium investigates surface roughness, kerf width, cutting speed specimens based orthogonal tests. Five optimized using grey correlation method response method. The roughness 1.744 μm, width 215.432 24.759 mm 2 ·min −1 found to be best process indicators, with errors 3.3, 3.2, 12.5% compared predicted values. results show that value reduced 50.9%, 29.4%, increased 23%, which proves accuracy
