Abstract：

According to the characteristics of progressive die, a constraint\|based assembly tree is proposed to represent its function context and constraints. In order to update the assembly model quickly, a variable\|expression\|based algorithm for solving the constraints is applied. As a result, the top\|to\|down design for progressive die structure can be implemented easily.
