When producing a matching part for good mating with its counterpart (assembly part), good matching accuracy between the matching part and assembly part is highly required. The matching errors are influenced by not only the errors of the matching part but also the errors of the assembly part. Because the errors of an assembly part could be different from others, it is very difficult to have very good mating accuracy, if the manufacturing of a matching part does not take the actual errors of the assembly into account. Furthermore, it will need additional off-line assembly mating tests to find a good mating pair. This study proposes an error-matching compensation method to solve the not-good-mating problem for manufacturing assembly modules with good matching accuracy. In this method, the actual errors of an assembly part are directly in-line measured and used to compensate the machining process of a matching part so that a dedicated part with the good mating condition can be on-line made for the error-measured assembly part. In addition to having better matching accuracy, this method also provides advantages of high production efficiency and cost saving, because it will not need the off-line mating test to find good mating pairs. This method also includes a function of in-line auto-generation of error compensation NC programs to support continuous production. In this study, error analysis of two mating types (planar mating and triangle mating) were explored and discussed. The Human–Machine Interface was built with the use of C# language. Finally, machining experiments with in-line measurements were conducted to verify the proposed method. The experimental results have shown the feasibility and effectiveness of the proposed method.

当制造匹配部件以与对应部件（组装部件）良好配合时，非常需要匹配部件与组装部件之间的良好匹配精度。匹配误差不仅受到匹配零件的误差的影响，而且还受到装配零件的误差的影响。由于装配零件的误差可能与其他零件的误差不同，因此，如果匹配零件的制造未考虑装配的实际误差，则很难具有非常好的配合精度。此外，将需要进行额外的离线装配配合测试以找到良好的配合对。提出了一种误差匹配补偿方法，以解决匹配精度较高的装配模块的配接不良问题。用这种方法 直接在线测量装配零件的实际误差，并用于补偿匹配零件的加工过程，以便可以在线制造具有良好配合条件的专用零件，用于误差测量的装配零件。除了具有更好的匹配精度外，该方法还具有生产效率高和节省成本的优点，因为它不需要离线匹配测试即可找到良好的匹配对。该方法还包括在线自动生成误差补偿NC程序以支持连续生产的功能。在这项研究中，探讨并讨论了两种配合类型（平面配合和三角形配合）的误差分析。人机界面是使用C＃语言构建的。最后，进行了在线测量的机加工实验，以验证所提出的方法。实验结果表明了该方法的可行性和有效性。
