AbstractSingle point incremental forming (SPIF) is a method which allows better formability properties compared to forming processes using a sheet metal die. However, the production time is considerably higher compared to using a die. Therefore, this method is generally used in low production quantities or in prototype manufacturing. In the present work, DP600 Dual Phase sheet material are selected for SPIF. Two material thicknesses were took (1mm, 1,5mm) and a truncated cone form was designed with three different wall angles. The finite element (FE) modeling of SPIF was generated with and without applying a pressure force from lower side of the sheet material. The FE analyzes have been done by using Abaqus software. It was determined that fluid assisted SPIF application caused to homogenously distribute the wall thickness of the sheet material while forming and increased the forming properties of the sheet metal.
