Single-Point Incremental Forming (SPIF) is a flexible technology that can form a wide range of sheet metal products without the need for using punch and die sets. As a relatively cheap and dieless process, this technology is preferable for small and medium customised production. However, the SPIF technology has drawbacks, such as the geometrical inaccuracy and the thickness uniformity of the shaped part. For the purpose of determining the optimal value for the technological parameters from the experimental results when evaluating the forming ability through the strain angle α during the processing of SUS 304 sheet material by SPIF technology. The article has conducted experiments to collect parameters; and experimental planning to establish a mathematical model, determine the optimal value for the parameters of the machining process such as tool diameter, tool feed and tool running speed.
