AWJ Cutting: The Technological Head Vibrations with Different Abrasive Mass Flow Rates

Abstract:

The paper presents results of the technological head vibrations acceleration amplitude evaluation and their corresponding frequency spectrums due to changes in the abrasive mass flow at division of abrasion resistant steel on a particular work with AWJ technology. The waveforms of technological head vibrations acceleration amplitude and their frequency spectrums are evaluated for the unworn directing tube.
