在计算机辅助设计（CAD）系统中以自由曲面表示的薄板广泛应用于制造过程。定位块和销，统称为定位器，是最常见的夹具，用于连接和组装板材。在本文中，利用稳健的设计方法来优化引脚布局，使板材变化，表达为某些关键产品/工艺特征点（KPCs）的平移和方向变化，被最小化。该方法的优点是可以定量地获得面板上任意点的定位变化，从而可以从无限多可行设计中选择最优引脚设计。在此基础上，还将提出一些有用的引脚设计准则。
Sheet panels, represented as freeform surfaces in a CAD system, are widely used in manufacturing processes. Locating blocks and pins, collectively known as locators, are the most common fixtures for the joining and assembly of sheet panels. In this paper, a robust design approach is utilized to optimize the pin layout so that the sheet panel variations, expressed as translational and orientational variations at certain key product/process characteristic points (KPCs), are minimized. The advantage of this approach is that the locating variations at any given point on the panel can be obtained quantitatively, and hence, the optimal pin design can be selected from among an infinite set of feasible designs. Based on the analyses, some useful pin design guidelines will also be proposed.
