Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Mechanical Design and Production Summary: The objective of this work is to optimize Electrical Discharge Machining process parameters of (AL-CNT) in order to reach to optimal Material Removal Rate (MRR), Electrode Wear Ratio (EWR) and Average Surface Roughness (Ra). The Machining parameters are machining-on time (Sec), Discharge Current (A), Voltage (V), total depth of cut (mm), and %wt. CNT added. Another objective is to build mathematical models for all responses as function of significant process parameters using RSM. Experimental results show optimum levels for material removal rate at %wt. CNT (0%), high level of discharge current (6A) and low level of voltage (50 volts), optimum levels for Wear electrode ratio at %wt. CNT (5%), high level of discharge current (6A) and optimum levels for average surface roughness at % wt. CNT (0%), low level of discharge current (2A) and high level of depth of cut (1mm)
