Hybrid abrasive electrochemical grinding machining of alloy steel K110

Abstract EN

In this research, the effect of the Al 2O3 abrasive particles on metal removalrate of the electrochemical grinding machining process was studied.

Allexperimental works were performed at different voltages (9 and 11.5V), differentfeed 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).

Theabrasive particles powder weight percentages were varied from 2.5 to 7.5.

In orderto study the effect of the abrasive particle powder, the results of the electrochemicalgrinding (ECG) were compared with the results of the abrasive electrochemicalgrinding (AECG).

All experiments were performed for K110 alloy steel.

The metalremoval rate was determined by weighing the samples before and after machining, then dividing by the time of machining.

Digital weight balance with 0.001gaccuracy was used.

The results revealed that the metal removal rate increases byincreasing the weight percentage of the Al 2O3 abrasive particles up to 5 wt.

% thendecreases.

In addition, the effect of the abrasive particles was decreased byincreasing the feed rate, salt electrolyte concentration and decreasing the depth ofcut.

The results of the electrical current show that the electrical current decreases ata percentage more than 5 wt.

% Al 2O3.
