Increasing the Efficiency of Hydroabrasive Cutting through the Choice of Rational Cutting Modes by Acoustic Emission Method

The authors examine the problem of expedited evaluation of the waterjet cutting performance at the technological preparation stage by the acoustic emission method. The results of numerical calculations of the hydroabrasive cutting process in two- and three-dimensional formulations are presented; and the results are compared. The experimental results of hydroabrasive cutting of different materials with a varying concentration of the abrasive material are given. The existence of the optimal efficiency mode of hydroabrasive cutting is shown. The experimental data is compared with the simulation results. The results obtained show a correlation between the waterjet cutting efficiency and the acoustic signal power.
