Study on Tool Wear Monitoring Based on Milling Force
-
摘要: 以铣削实验为基础,分析了铣削力中包含的与刀具磨损状态有关的频谱特征,分析了切削用量对切削力功率谱的影响,对比了切削力各分量的特征对刀具磨损状态的反映.从对铣削力功率谱的分析中得出:径向力功率谱对刀具磨损状态更敏感,其中有与刀具磨损状态密切相关的特征频段,而切削用量对该特征频段的影响不明显;还通过对切削力的时域分析,讨论了铣削力中径向力和切向力的分力比值对刀具磨损状态的反映.Abstract: Based on the milling experiment,the characteristics included in milling force and concerning the conditions of tool wear was analyzed,the influence on cutting force spectra for cutting regime was analyzed,and the comparison among the effect to conditions of tool wear for components of cutting force was made . Through the analysis to the milling force spectra,it indicated that: 1)the radial force spectra is more sensitive to the conditions of tool wear,2)there is characteristic band in cutting force spectrum,which has close relation with the conditions of tool wear and is out of the relation to the cutting regime . And through the analysis to cutting force in time domain,the relationship between the conditions of tool wear and the components ratio of radial force and tangential force was discussed.
