该方法使特征定位基准在特征造型过程中保持不变,且不随特征定位约束参数的改变而变化,能很好地满足参数化变动设计与拓扑结构变异的要求。
This method keeps the location base of form feature invariance during the feature modeling and editing, and it is suitable for feature parametric variational design and topological variation.
通过对非设计基准定位的工件批量性加工实例的分析,探求其工序尺寸及其偏差的简捷计算法。
Through analyzing the example of a batch of production located by non-design reference, the paper seeks a kind of simple and convenient arithmetic for the size and deviation of working procedure.
精基准选择:要符合基准重合原则,尽可能选设计基准或装配基准作为定位基准。
Fine datum choice: Must conform to the datum superposition principle, chooses the design datum or the assembly datum as far as possible takes the localization datum.
