Abstract

In this research, the effect of the Al
 
2O3 abrasive particles on metal removal
rate of the electrochemical grinding machining process was studied. All
experimental works were performed 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). The
abrasive particles powder weight percentages were varied from 2.5 to 7.5. In order
to study the effect of the abrasive particle powder, 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 metal
removal rate was determined by weighing the samples before and after machining,
then dividing by the time of machining. Digital weight balance with 0.001g
accuracy was used. The results revealed that the metal removal rate increases by
increasing the weight percentage of the Al
 
2O3 abrasive particles up to 5 wt. % then
decreases. In addition, the effect of the abrasive particles was decreased by
increasing the feed rate, salt electrolyte concentration and decreasing the depth of
cut. The results of the electrical current show that the electrical current decreases at
a percentage more than 5 wt. % Al
 
2O3.
