针对两个不同的没有技术图纸的部分损坏的零件，通过CMM获得其CAD数据并创建CAD模型，将获取的CAD模型传输到软件的CAM模块，通过后置处理获取G代码，最后由数控铣床对零件进行数控加工，从而实现修复。由于连续性对构成几何模型的自由曲线和曲面非常重要，在修复和重建过程中，考虑参数和几何连续性，并采用等参照线法对表面连续性进行分析。

Getting the CAD data attd founding the CAD models of the two different damaged parts without technical drawings by CMM, the G codes were gotten by the way of post-processor after transferring the CAD models into the CAM module. Then the parts were manufactured by CNC milling machine. Because continuity was very important for forming free curve and surface, during repai- ring and rebuilding process, the parameters continuity and geometric continuity were considered. The surface continuity was analyzed through the way of the equal datum line.
