| Abstract | ||||
| A rigid abright drill provided the ratory motion for a brass disc employed as the tool having no embeded abrasive material, Sodium Chloride and Sodium Hydroxide having different concentrating rates between (10% - 50%) were employed as electrolytes covering the gab between the tool and workpieces. Mild steel, free machining -rass and pure aluminum in the as-received conditions were employed as workpieces. Material removal rates were found to be greater for smaller gap widths, higher speed of revolution, greater gap voltage, higher percentages of electrolyte conceration and greater electrolyte velocity for all workpiece materials especially when using sodium chloride. As the material removal rate increases, consequently workpiece surface temperature rises. Such temperature rises all-over the entire range did not exceed + 30°C. Workpiece surface finish were found to improve for higher rates of material removal for mild steel and free machining brass only. No such improvements were noted after aluminum machining except at high tool speeds. Deep scatered scratchs in aluminum specimens were noted at lower tool speeds. | ||||
