Abstract
The electrochemical grinding machining process has received wide acceptance in the aircraft turbine industry for the production of blades, vanes, and honeycomb seal rings. It has also become a standard machining process in the production of hypodermic needles. The increased use stainless steel and new exotic material for applications such as medical devices, instruments and forceps, pacemaker shells, precision nozzles, instrument coupling, and air rotor motors have all successfully been accomplished with ECG. In this research, the effect of the Al2O3abrasive additions on metal removal rate and surface roughness of the electrochemical grinding machining process at different voltages ( 9 and 11.5V ),different feed rates (6.74, 13.63, 22.55 and 27.44 Ipm), different electrolyte concentrations (10, 15 and 20 wt. % NaCl) and different depths of cut ( 0 and 0.1 mm)was experimentally investigated. The abrasive particles powder weight percentages were varied from 2.5 to 7.5, in steps of 2.5. To study the effect of the abrasive particles powder on the MRR and the SR of the ECG process; the results of the electrochemical grinding (ECG) were compared with the results of the abrasive electrochemical grinding (AECG).All experiments were performed for K110 alloy steel.
The results were used in the design of educational situations in the course (finishing and non-conventional machining processes) for fourth year students at the Faculty of Industrial Education, Helwan University, Production Technology Division
