Study of mould deep drawing based on fuzzy synthetical evaluation theory

The fuzzy mathematics has been applied in the mould design in this paper.Taking the cylindrical part for example,it introduces the fuzzy synthetical evaluation theory application of the fuzzy mathematics to the deep drawing of the mould design.It analyzes the main factors of deep drawing-the limit drawing coefficient.And pointed out the fuzzy adjustable factors and unchangeable factors for the first time,explains the theory and principle of the fuzzy adjustable factors which inflects the limit drawing coefficient and summarizes and makes the improvement on the predecessors' experiences and skills.The process could be implemented by computer programming.
