定位误差分析是机械设计、制造及其自动化生产中的重要环节,直接决定加工零件的加工质量和生产成本,也是制约生产效率提高的一个瓶颈问题,分析了定位误差产生的原因、定位误差的计算方法及其在典型零部件加工过程中应用,揭示定位误差存在的本质,即是由基准不重合误差和基准位移误差两方面因素共同作用的结果,为减小定位误差提供了科学的研究基础。
Positioning error analysis is an important link in mechanical design, manufacture and automatic production. It directly determines the processing quality and production cost of the machined parts, which is also a bottleneck that restricts the improvement of production efficiency. The causes of positioning errors and the calculation of positioning errors are analyzed Method and its application in the processing of typical components to reveal the essence of the positioning error, that is, the result of the two factors of the reference misalignment error and the reference displacement error, and provide a scientific basis for reducing the positioning error.
