英文摘要：

According to the unsteady state of waved-edge milling blade coupled field, the temperature field and stress field of milling blade are forecast by Levenherg-Marquardt algorithm of BP neural network based on the milling force and temperature test and finite dement analysis. Applying Fuzzy mathematics theory, the fuzzy comprehensive evaluation system for waved-edge milling blade is developed by VC ＋ ＋ based on machining reqnirements and expert analysis. The stress field, temperature fieM and coupling field of waved-edge milling blade under multi-factor actions can be evaluated to supply the support for reconstruction of milling blade with 3D complex groove.
