模运算

The modeling of the rolling forging dies is different from that of the other numerical simulation. It belongs to the typically free form face modeling.lt easy give birth to unparameters in modeling, which makes boole operation fail. So we model the rolling forging dies with power-function UG and bring forward the ideal modeling methods.

前轴辊锻模的建模不同与其它数值模拟建模，它属于典型复杂曲面建模，在建模过程中常常出现非参数化的情况，导致布尔运算失败，针对这种问题采用功能强大的UG进行参数化建模，提出了理想的建模手段。
