摘　　要：用样条函数拟合曲线具有型值点个数不受限制,保证曲线光滑,便于模具型腔曲线分析等优点。因此,这里采用三次样条函数拟合曲线构造模具型腔廓线,其型值点由已有模具型腔测得。然后分析构造出模具型腔廓线的成形规律,使型腔表面缺损处可获得精确的修正。Cubic spline function fit die cavity outline, it have some advantages, The number is not limit of model points, it can guarantee curve smooth, meanwhile it is easy to analyze die cavity outline. So it adopt cubic spline function to structure die cavity outline in this article, the model points may be surveyed on die cavity surface. After that, analyze shaping regularity of die cavity outline, it can make damage point of die cavity surface obtain precise repair.
