Measurement and analysis of the signals of a high pressure waterjet pump

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 signals have been analysed with the aim to design a on-line and non-intrusive monitoring and diagnostic system.
