| Abstract: | In Present stUdy, the acoustic emission signal from the metal cuting process was monitored to indentify wear state of the cutting tool edge: the flank wear of the cutting tool was measured by monitoring the gradual increase of the acoustic emission signal level; in-Process detection of the cutting tool fracture was the possible by monitoring the stepwise increase in the ampliltude level. A microprocessor was uesd to process the data obtained and to generate the signal of the cutting tool fracture. The threshold value of acoustic emission signal owing to cutting tool fracture was studied too. |
