Study on Tool Wear Monitoring Based on Milling Force

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.
