| dc.description.abstract | Optimization value of material removal rate
(MRR) and overcut (OC) are important things in electrochemical
machining (ECM), especially in production of multilayered
Microfilter. Because ECM process can be influenced by voltage and
feed rate, to detect the effect of both factors on MRR and OC, then
conducted research with 3 levels of voltage (13, 15 and 17 volts), 3
levels of feed rate (5,5, 6,5 and 7,5 mm/min) and 3 times the
replication of full factorial design approach (FF). Machining was
done dynamically with a diameter of 4 mm copper electrode and
workpiece material such as stainless steel 204. The results obtained
from this research that voltage, feed rate and interaction of two
factors have a significant influence on the value of MRR and overcut,
where its influence are encapsulated in form of linear regression
models. Besides that, the highest MRR obtained at voltage of 17
volts and feed rate 7,5 mm/min with value 6,37 × 10-4 g/s, while for
the lowest overcut obtained at voltage of 13 volts and feed rate of 6,5
mm/min at 0,208 mm. Based on the analysis for both response
generated optimum conditions at voltage 17 volts and feed rate of 6,5
mm/min with value of MRR 5,533 x 10-4 g/s and value of overcut
0,351 mm. | en_US |
