Özet:

 

This paper presents the experimental investigations on  addition of aluminium metal powder to dielectric fluid in electric  discharge machining (EDM).  As more emphasis is given nowadays to the  green manufacturing concept, the present investigation uses distilled  water mixed with aluminium powder as dielectric fluid instead of  conventional hydrocarbon-based oils.  The workpiece and electrode  materials chosen for the investigation are W300 die-steel and  electrolytic copper, respectively.  Taguchi design of experiments is  used to conduct experiments by varying the parameters peak current,  pulse on-time, concentration of the powder, and polarity.  The process  performance is measured in terms of material removal rate (MRR),  electrode wear ratio (EWR), average surface roughness (Ra), and white  layer thickness (WLT).  The experimental results indicate that the  polarity significantly affects the machining performance.  Signal-to-noise (S/N) ratio and the analysis of variance (ANOVA) are  employed to find the optimal levels for the process parameters to  achieve maximum MRR, low EWR, Ra, and WLT values.
