The aim of this thesis is to develop an unconventional cartesian plotter 2D for food cutting using the water jet technology. First of all we analysing the environment condition of work of the machine and we construct the machine according to the constraint carried out by the analysis. We develop an innovative placement of motors that allows to fix both motors at the machine chassis in order to have fewer moving parts than a traditional 2D plotter. The moving of the nozzle is made by a special configuration of belts and pulleys. The final result is a fully functionating machine with a Human Machine Interface.
