OPTIMASI MULTIRESPON PADA PROSES EDM SINKING BAJA ST 42 DENGAN MENGGUNAKAN METODE TAGUCHI DAN FUZZY LOGIC
Abstract: The optimization
technique of machining parameters considering multiple performance
characteristics of non conventional machining EDM process using Taguchi method
combined with fuzzy logic is presented in this study. ST 42 steel was chosen as
material workpiece and graphite as electrode during this experiment.
Performance characteristics such as material removal rate and overcut are
selected to evaluated the effect of
machining parameters. Current, pulse on time, pulse off time and
discharging time/ Z down were selected as machining parameters. The experiments
was conducted by varying that maching parameters in three different
levels. Based on the Taguchi quality
design concept, a L27 orthogonal array table was chosen for the
experiments. By using the combination of
fuzzy logic and Taguchi, the optimization of complicated multiple performance
characteristics was transformed into the optimization of a single response
performance index. Optimal levels of machining parameters were identified by
using fuzzy logic method. The
statistical application of analysis of variance
was used to determine the relatively significant machining parameters.
The result of confirmation test indicted that the determined optimal
combination of machining parameters effectively improve the performance
characteristics of the machining EDM process on ST 42 steel.
