A Fuzzy Logic Approach for the Pulse Classification of Electro Chemical Discharge Machining (ECDM)

This paper presents the pulse classification of the ECDM process using Fuzzy Logic (FL). An Electro Discharge Machining (EDM) machine was modified by incorporating an electrolyte system and by modifying the control system. Gap voltage and working current waveforms were obtained. A fuzzy rule base was designed and simulated to classify pulses. Different ECDM process variables were considered to design the pulse classification rule base. The performances were compared by changing the process variables and by changing rules in the fuzzy rule base. The classification accuracy was measured in the classification system. A quantitative analysis was performed to evaluate the fuzzy pulse classifier with different process variables and with different fuzzy rules for the ECDM machine.
