Starting from the correlation between electric input, mechanical and fluid-dynamic signals a set of index able to define a suitable "footprint" of a water jet system in normal working conditions has been defined. An on-line and non-intrusive monitoring and diagnostic system for this kind of device has been designed implementing an algorithm defined on the basis of the proposed "footprints"
The waterjet (WJ) technology, whose characterization involves phenomena belonging to different fields of physics, presents some particular aspects which make it essential in some manufacturing operations where it is important to cut special or hard to machine materials by means of a cold process. In the present work, the correlations between the electric input signals, the mechanical and the fluid-dynamic...
