本文介绍的汽轮机转子ＣＡＰＰ系统，采用了新的描述方法和工艺规程生成策略。由于应用了信息容量极大的输入信息树和新的编码系统，成功地介决了结构极为复杂的转子的信息描述，为工艺规程的自动生成奠定了基础。同时，新的工艺规程生成策略不仅介决了复杂的排序问题。亦使生成工艺规程的推理过程得到了简化，实践证明，本系统采用的新方法具有相当的先进性，为重工业中类似的大型复杂回转体类零件的ＣＡＰＰ系统开发提供了较好的方法。 This article describes the turbine rotor CAPP system, using a new description of the method and the process of generating rules and regulations. Due to the application of the input information tree with great information capacity and the new coding system, the information description of the extremely complicated rotor is successfully solved, which lays the foundation for the automatic generation of the process specification. At the same time, the new tactics generation strategy not only solved the complicated sorting problem. The reasoning process of generating process rules has also been simplified. Practice has proved that the new method adopted by the system is quite advanced and provides a good method for the CAPP system development of similar large and complex rotating body parts in heavy industry.
