The article presents the results of two interrelated studies. The first is related to assessing the possibility of using a water-polymer ultrajet as a diagnostic tool for cutting tools for the disposal of plastics. The second is related to the development of a directly new tool design. As a result of research, it was shown that both the method of water-polymer diagnostics and the proposed design of the knife have prospects for practical application. A model of a composite tool for the disposal of composites is proposed, which potentially has high operational properties. The research results are confirmed by the data of a comparative analysis of various diagnostic methods and strength calculations of the tool.

The article reflects the possibility to solve the problem of choosing waterjet cutting optimum conditions based on acoustic emission data. Modeling of the waterjet cutting process by the finite-element method is carried out. The existence of an optimum point in the waterjet cutting performance is shown. Corresponding experiment data is gathered and compared with the simulation results. The correlation between the waterjet cutting performance and the acoustic emission data is shown.
