Abstract

The experimental regularity of acoustic emission amplitude parameters change at ascending of composite material machining speed is reviewed. Is determined, that ascending of acoustic emission signal amplitude average level and its standard deviations are described by linear functions. The regularity of acoustic emission signal amplitude average level dispersion change is described by a power function. The sensitivity of acoustic emission amplitude parameters to an alteration of composite material machining speed is determined. It is shown, that the percentage increment of acoustic emission signals amplitude average level dispersion advances a percentage increment of amplitude average level and its standard deviation. It is shown, that experimental and idealized regularity of acoustic emission signals statistical amplitude parameters change at ascending of composite material machining speed have good agreement with each other.
