INVESTIGATION OF ENERGY INPUT AND MACHINING EFFICIENCY AT ABRASIVE WATER JET CUTTING

Abrasive waterjet machining is a widely used technology for cutting metal, ceramic and polymer sheets. Nowadays, it is becoming important that the applied technological parameters are efficient and economical. This requires the appropriate selection of the most important technological parameters. In this paper, we report on research in which the combined effect of technological parameters, i.e. the relationship between the input energy and the efficiency, was examined when machining three material qualities (metal, ceramic, polymer). The article examines the relationship between the depth of kerf and the amount of energy input by the jet and formulates conclusions regarding the machinability of different materials.
