Abstract: Continuous Multi-Point Forming (CMPF) is an advanced sheet metal forming technology. It can manufacture three-dimensional surfaces of different shapes by adjusting the curvatures of flexible rollers and displacement of upper flexible roller. CMPF experimental equipment was designed. Finite Element Analysis (FEA) model was established. To show the characteristics of CMPF, conventional roll bending was compared with it. Process of CMPF and action force between flexible rollers and sheet metal were researched by numerical simulation method; simulation results can offer assistance to optimise the design of CMPF equipment. Spherical, saddle and twisty surfaces were simulated and their experimental results were presented.
Keywords: CMPF; continuous multi-point forming; 3D surfaces; flexible rollers; experiment; numerical simulation; sheet metal forming; modelling; finite element analysis; FEA; roll bending.
