摘要
研究了基于 NURBS的形位公差装配成功率的计算方法。阐述了利用统计方法获得模拟加工表面采样点和 NURBS曲面插值构造加工表面 ;研究模拟检测过程来估算装配成功率的方法 ;就不同公差原则对装配成功率的计算展开了讨论。
This paper presents a scheme for calculating geometric tolerance stack-up yield based on NURBS. First, a set of points generated from the machining process probability distribution, and a NURBS surface is interpolated to fit the generated points representing the manufactured surface. Then, the inspection of the part is simulated to evaluate geometric tolerance stack-up yield, and the calculation methods on different tolerancing principles are discussed.
