The technology of material cutting by high speed
abrasive water jet presents one of the fastest developing
technological processes of material cutting. At present,
this technology offers very accurate, computer controlled
form cutting of materials by cold way without mechanical
deformation with minimal impact. These attributes place
this technology on the position of continuous use in the
future presenting the great perspective to spread in many
industries, mainly where the materials of top manufacture
qualities are used. Besides numerous advantages of the
technology there is a negative phenomenon in the AWJ
production system – noise significantly influencing
workers, mainly the operators. The objective of this report
was a simple identification of the influence of factors
(independent variable) of AWJ on the acoustic pressure
level LAeq (dependent variable), where the acoustic load in
an operation with AWJ technology was evaluated in the
particular process of material cutting. On the basis of the
experiments results following conclusions were made
