英文摘要：

Based on the experiments on milling the carbon structural 45 steel 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, the paper have experiment study on the impact disrepair. Firstly, the finite element analysis and blurry synthetical judgement of the 3D stress field were carried on, and forecast that the anti-impact disrepair capability of the waved-edge milling insert is choiceness. Secondly the papaer finds out the difference of the impact disrepair invalidation types between different grooves milling inserts by the experiments. Based on the plentiful and systemic impact disrepair experiments, the impact disrepair life cumulating distribution function mathematic model is built. This paper proves that the anti-impact disrepair capability of the waved-edge milling insert is choiceness. All these studies provide the theoretic and experimental bases for solving the cutter disrepair which is the key problem in the automatization production and groove optimization.
