The interpolate algorithms of three-order NURBS curve and double three-orders NURBS surface are presented. The expressions of partial derivative and normal curvature of NURBS surface are derived by the theory of differential geometry. The geometric characteristics of different curvature area of the free-form surfaces are analyzed in detail. All these work lays a theoretical foundation for constructing the cutter location calculating model of free-form surfaces NC machining. 2 On the basis of analyzing the methods of cutter path generation, the standard of evaluating the various methods of cutter path generation is presented. The method of generating cutter path with constant scallop height is presented for the first time.
本文以提高复杂曲面多坐标数控加工精度和加工效率为目的,在对国内外研究现状进行深入分析的基础上,对数控编程中各环节的关键技术问题进行了深入研究,主要内容包括以下几方面: 1 分析了复杂曲面各种造型方法的优缺点,给出了根据各种边界条件所确定自由曲面的NURBS表示方法以及三次NURBS曲线曲面反算算法;用微分几何理论推导了NURBS曲面的偏导矢及法曲率计算表达式;对曲面不同曲率特性区域的几何特征进行了深入分析,为建立复杂曲面的数控加工刀位计算模型奠定了理论基础。
