【 摘 要 】

The hydraulic support is introduced into the single point incremental forming technology to obtain a new single point incremental forming technique with an isostatic pressure flexible support. Thereby, the forming process instability and the defects of the part due to the suspension of the sheet are eliminated. The isostatic pressing system are designed and developed to experimentally study the force in the forming process. The experimental results show that the horizontal forces Fx and Fy in forming process of the new technology have a certain increase compared with the force of the traditional single point incremental forming, but the increase is not large. However, the axial force Fz changes relatively large. As the isostatic pressure increases, the axial force increases.
