根据凸轮机构的检测数据利用三次周期样条函数插值法对凸轮实际廓线进行曲线拟合。
Curve fitting of the actual CAM profile with the Cubic-periodic spline function according to the measured data of the CAM.
在拟合每个轮廓线时，先用非接触测量系统测出的数据反算出ee样条曲线控制多边形的顶点。
When fitting each contour line, the points measured by non - contact measuring system are as the top points about control polygon for forming EE spline curve.
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。
So it adopt cubic spline function to structure die cavity outline in this article, the model points may be surveyed on die cavity surface.
