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,通过对耐热钢的面铣加工进行刀片粘结破损数学模型的研究。首先,进行铣刀片切削温度实验,对铣刀片粘结破损机理进行分析;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,建立铣削温度与前刀面最大粘结破损深度之间的数学模型,分析铣削温度对刀具粘结破损的影响规律。研究成果为解决自动化生产中刀具破损这一关键技术问题打下理论与试验基础。Based on the edge milling experiments on milling the refractory steel with the flat rake insert and the wavedinsert which is developed by HarBin University of Science and Technology, we have studied on the adhering disrepair mathematic model. We have milling temperature experiment and study on the adhering disrepair mechanism of the milling inserts. We find out the difference of the adhering disrepair invalidation types between different grooves milling inserts by the experiments. Based on the experiments, we build the mathematic model between depth on rake face and study the principle that the milling these studies provide the theoretic and experimental bases temperature and maximal adhering disrepair temperature affecting adhering disrepair. All for solving the cutter disrepair which is the key problem in the automatization production.
