In contrast to Robust Design applications, the simulation of a mechatronic system including both mechanical and electrical parts requires a different strategy for the investigation of its robustness. Differences mainly results from interactions between the mechanical and the electrical part of the mechatronic system. Micro Electrical Discharge Machining (
EDM) is good example for mechatronics application. This paper presents an approach to evaluate robustness of mechatronic comfort systems. At the outset, this study revolves around modeling of the various constitutive blocs of the machine through the appliance of the ‘Matlab/Simulink’ as well as analyzing the strength of this model by resorting to the same software programme of simulation . Having gone through the phase of simulation, the main outcomes of this experience where noticed at the level of the parameters defining the drilling such as the gap and the position of the electrode.
