This paper aimed to present the methods to improve the forming accuracy for water jet incremental sheet metal forming. The study focuses on the process parameters and the forming accuracy based on the experiments. Firstly, some experiments was carried out to evaluate the deformation effect of sheet metal in water jet incremental sheet metal forming process with respect to some key parameters, such as water jet pressure and feed velocity. Then, the influence of layer on deformation was analyzed, and the theoretical model of forming accuracy and two methods to improve the forming accuracy were presented. Finally, the circular truncated cone parts formed with different methods and the profiles were measured with a coordinate measuring machine. Compared with the designed model geometry, the experimental results showed that an achievable forming accuracy could be obtained by the presented two methods.
