Notes:
Based on the theoretic analysis and experiments on milling the carbon structural 45 steelwith the flat rake milling insert and the waved-edge milling insert with complex 3D grooves whichis developed by HarBin University of Science and Technology, we have studied on the impactdisrepair mathematic model and groove optimization. On the basis of the milling force mathematicmodel and force density function of the waved-edge milling insert with complex 3D grooves theauthor built, we have the finite element analysis and blurry synthetical judgement of the 3D stressfield, and forecast that the anti-impact disrepair capability of the waved-edge milling insert ischoiceness. We find out the difference of the impact disrepair invalidation types between differentgrooves milling inserts by the experiments. Based on the plentiful and systemic impact disrepairexperiments, as the emphasis in this paper, we build the impact disrepair life cumulatingdistribution function mathematic model by the mathematics statistic method and have contrastanalysis of the impact disrepair average lives between the two types of milling inserts, and provethat the anti-impact disrepair capability of the waved-edge milling insert is choiceness. All thesestudies provide the theoretic and experimental basis for solving the cutter disrepair which is the keyproblem in the automatization production and groove optimization
