摘　　要：首先分析了虚拟企业环境下特征识别特点,并对STEP文件中的类型面之间的组合进行总结归类。在此基础上运用模糊推理对任意零件的STEP文件中的两两类型面进行组合推理,通过选用不同的模糊蕴涵规则可以快速地初步确定推理结果,为进一步确定组成零件的基本特征奠定了基础。最后列举实例进行验证。The typical feature recognition under the condition of virtual enterprise was analyzed. The combination between the surfaces of the step file was summarized and classified. The two surfaces of the step file of arbitrary part were combined and inferred by the fuzzy reasoning. The reasoning results were rapidly and preliminary determined by the different fuzzy implication rules. This is the foundation for further determining the basic features of part. At last the example was listed to verify it.
