Abstract:

The plastic forming is classified to the integral forming and the local forming, and the local is again classified to the point,the line,and the face forming.The comparisons of the advantages and disadvantages between the different forming techniques were made and the differences and features of the die forming and the flexible forming as well as the sectional forming and the continuous forming.Based on the above discussions,an effective,continuous,and flexible forming concept and a multipoint rolling technique by using the bendable,adjustable,and flexible rollers were proposed.A flexible rolling device for the freeform surface parts was developed and its experimental test was performed.The results show that the proposed concept is feasible and practicable.

Key words: materials synthesis and processing technology, plastic forming, multipoint roll forming, freeform surface, continuous forming, flexible forming
