Electric pulse assisted incremental sheet forming (E-ISF) has been proven to enhance the formability of Ti-6Al-4 V sheet. However, the high electro-thermal effect induced by electric pulse could result in severe surface oxidation and excessively coarse grains of the final parts. In this study, a water-cooling system was employed to fabricate high-quality Ti-6Al-4 V parts during electric pulse assisted incremental forming. The excellent surface finish of Ti-6Al-4 V parts fabricated using water-cooling system can be attributed to the low forming temperature. Additionally, the activated non-basal slip can lead to the texture transition from {0001} 〈01−10〉 to {11−20} 〈0001〉 texture, together with the dynamic recrystallization of α and β grains, resulting in forming heights larger than 15 mm. This study indicates that the water-cooling system is an effective strategy for achieving low surface roughness, high formability, and geometric accuracy in Ti-6Al-4 V parts during the electric pulse assisted incremental sheet forming.
