Technical Possibilities of Noise Reduction in Material Cutting by Abrasive Water-jet

Th e technical procedure of noise reduction in material cutting by abrasive water-jet is described in this paper. The paper is aimed at the implementation of technicchnical possibilities of noise reduction in the cutting of material by abrasive water-jet technology. Both the theoretical and experimental investigations were performed to verify and specify the new findings in the reduction of acoustic sound pressure at abrasive water-jet machining of engineering materials. By means of identification, the influence of pressure and traverse speed on acoustic sound pressure level LAeq was identified. Furthermore, a possible way of acoustic pressure level reduction at the technological node of material cuttining by abrasive water-jet by means of technically relatively simple adjustment, is described.
