鞋楦曲面数字化级放方法的研究

Research on the method of digital last of boot tree

根据鞋楦级放原理与级放规范,研究了实现鞋楦曲面数字化级放的方法.着重分析了通过坐标系变换解决母楦曲面数据空间坐标系与级放空间坐标系不一致产生的问题并给出了解决方法,提出通过双线性内插法和设置围度与长度级放误差补偿因子来提高鞋楦级放精度的方法.

According to the principles and standards of the last of boot tree, we make research on the method of realizing digital last of boot tree surface in this article and put emphasis on the improvement of the last accuracy of boot tree by the change of coordinate system which solves the problems arising from the discordance between the digital coordinate system of mother boot tree and the last coordinate system, and by means of bilinear interpolation and error compensation of length last.
