| Abstract: | Multi Point Flexible Forming (MPF) is an advanced processing technique for 3D sheet metal parts. The theory and method on the blank design, determination of forming path and transition area design of sectional forming in MPF are introduced. Initial blanks for ellipsoidal objective surface and an irregular surface were calculated and the optimum forming path for a saddle objective surface was designed by the presented methods. |
