Estimation of Major Parameters of Cross Wedge Rolling by Using Fuzzy Reasoning Method

The Selection of processing pararneters is the most important step for the cross wedge rolling designing. The fuzzy information processing methods are used to analyze the data of dies, and the fuzzy relationships among technological parameters as well as theer applications are presented. By using the fuzzy reasoning methods, the parameters such as formation angle α, contraction ratio of area φ, can be determined automatically in the CAD system.
