Abstract

The possibility of applying the acoustic emission method for optimizing the technological modes and parameters of underwater waterjet cutting is considered in the article. It is concluded that the creation of a universal technological equipment that allows cutting, segmenting, perforation, and cleaning underwater structures is an urgent scientific and technical problem. As a result of the series of experiments, it was shown that the acoustic emission method can be effectively used to monitor and control the procedure of materials’ processing when performing various operations using unmanned underwater robot manipulators. Graphic dependencies connecting the amplitude values of the received acoustic emission signal on the underwater cutting process’s time were obtained. The schemes for conducting all experiments’ stages and used technological equipment are presented. It was found that the method of acoustic emission makes it possible to determine the moment of material’s piercing by a waterjet stream for subsequent transition to the process of hydrocutting along a predetermined path cutting or segmentation. In conclusion, the article gives the analysis of the results of experimental studies, guidelines and shared insights, and prospective research tasks.
