Improvement of the dimensional accuracy of a Ti-6Al-4V ripple disc during electric hot incremental sheet formingLi, Zhengfang ...The edge warpage of a Ti-6Al-4V ripple disc is a major forming defect during electric hot incremental forming, which can lead to a significant dimensional error. In this paper, a novel manufacturing ... method, namely the combination of electric hot incremental forming and electrically assisted sizing, has been proposed to improve the forming defect. The effect of process parameters on forming fracture was analysed in detail, and then an optimal combination of process parameters was obtained to ensure the successful forming of a Ti-6Al-4V ripple disc. On this basis, a sizing device and a sizing current were separately designed and analysed to eliminate the warpage defect of Ti-6Al-4V ripple discs. According to the experimental result, Ti-6Al-4V ripple discs can be satisfactorily fabricated through the method proposed.Source: Strojniški vestnik = Journal of mechanical engineering. - ISSN 0039-2480 (Vol. 70, no. 1/2, Jan.-Feb. 2024, str. 20-26)Type of material - article, component part ; adult, seriousPublish date - 2024Language - englishCOBISS.SI-ID - 187098371
