Correlation of cutting force features with too wear in a metal turning operation

摘要

Interrupted turning has been conducted and the cutting forces recorded on-line while measurements of the cutting tool wear forms were made. The acquired data were analysed in the time and frequency domain for cutting tool wear correlation. The method employed was geared towards developing an understanding of the spectra energy content of the dynamic cutting force signals and how it could be used as an input sensor signal in the development of a tool wear monitoring system. Analysis of the data indicated that the spectra energy content correlated well with the measured tool wear at certain frequencies.
