Language: russian

Annotation:

The regularity of acoustic radiation energy parameters change depending on cutting depth at machine work of composite material for thermoactivative model of surface layer destruction are obtained. The description of legitimacies change of acoustic emission signals energy average level, its standard deviation and dispersion from a cutting depth is conducted. Is rotined, that the most sensing parameters of acoustic emission to a cutting depth of composite material is the dispersion of acoustic emission energy average level resultant signal.

Key words:

acoustic emission, composite material, resultant signal, amplitude, energy, machining, statistical characteristics
