Abstract

Acoustic emission (AE) generated during turning was detected and analyzed in order to study tool wear development during metal cutting and investigate the possibility of applying AE techniques for in-process sensing of tool wear. Experimental tests were carried out on carbon steel using HSS tools under realistic cutting conditions. The influence of two wear parameters (maximum wear land and crater wear width) on AE activity was examined. The results are presented in the form of graphs. The analysis of the AE - wear curves provides useful indicators of unacceptable wear development in the tool. These could be used to identify the initiation of rapid breakdown and the moment for tool change in unattended manufacturing systems. A main drawback in applying AE techniques for tool wear monitoring is represented by the dependence of the response on cutting conditions, especially in the case of realistic cutting operations.
