Abstract

The paper gives the results of research to improve the stability of the jetforming elements waterjet systems by using a number of special coatings, shape and location of the application are installed on the basis of functionoriented approach. The influence of parameters destroyed gauge tube as jet forming elements is the quality of the process of waterjet cutting of critical parts. The results of modeling the formation of twophase flow and its movement in the gauge tube. It has been determined that the phenomena of wear of the hydraulic pipes have different intensities and mechanism. This determines the feasibility of functionoriented approach to the choice of means to ensure the required parameters of the element. It is concluded that the decrease in the intensity of material removal with the running of the tube and thus maintain its geometric parameters is possible through the use of appropriate coatings, thickness and physicalmechanical characteristics are selected based on the functionalcost features in accordance with an intensity and a view of the abrasive surface load.
