Experimental acoustic emission signals at compromise material machining

Abstract

The results of acoustic emission signals experimental researches at composite material machining are reviewed. It is shown, that the registered acoustic emission signal is a continuous signal with the hardly bluffly form. The statistical acoustic emission amplitude parameters at increase of composite material machining speed are determined. It is shown, that the ascending of machining speed results in ascending all acoustic emission amplitude parameters. However greatest ascending there is a dispersion of registered acoustic emission signal amplitude average level. The results of acoustic emission analytical investigations at composite material machining for a prevailing mechanical destruction its surface layer are reviewed. It is shown, that the simulation results have a good coordination with the results of experimental researches.
