摘　　要：针对哈尔滨理工大学开发的三维复杂槽型波形刃铣刀片和平前刀面铣刀片,对耐热钢的面铣加工进行刀片粘结破损的实验研究。首先,进行铣刀片三维温度场有限元分析,预测出波形刃铣刀片的抗粘结破损性能优良;其次,通过实验揭示不同铣刀片粘结破损失效形式的差异;在粘结破损实验的基础上,对铣刀片粘结破损机理进行分析。上述研究成果为解决自动化生产中刀具破损问题及槽型优选技术的研究打下理论与试验基础。Based on the experiments on milling the refractory stee with the flat rake milling insert and the waved-edge milling insert with complex 3D grooves which is developed by Harbin University of Science and Technology, we have experimental study on the adhering disrepair. We have the finite element analysis of the 3D temperature field, and forecast that the anti-adhering disrepair capability of the waved-edge milling insert is choiceness. We find out the difference of the adhering disrepair invalidation types between differ- ent grooves milling inserts by the experiments. Based on the adhering disrepair experiments, we have study on the adhering disrepair mechanism of the milling inserts. All these studies provide the theoretic and experimental bases for solving the cutter disrepair which is the key problem in the automatization pro- duction and groove optimization.
