Abstract

Single-point incremental forming (SPIF) has the potential to replace conventional sheet forming processes for customized and small batch size sheet metal products. In this research work, the operating parameters (i.e. step size, tool size, and forming speed) which can affect the formability during SPIF process were altered over wide ranges and their effect on the formability of a titanium sheet was investigated. A six-dimensional hyper-surface showing the influence of investigated parameters on the formability was developed by using a response surface methodology. The capability of the SPIF process to enhance the cold formability of titanium sheet was also examined. This was carried out by comparing the sheet formability in SPIF and stamping processes.
