Abstract
The major criteria covered in this study are Grain Refinement parameters and tensile strength of Aluminum 4032 alloy using the Taguchi technique and analysis of variance. The Taguchi technique of orthogonal L9 design experiment is carried out utilising an orthogonal array to define good refinement on alloy material and decrease vibration error for output prediction. Variation of supply input DC voltage from 20, 23, 26 V, amplitude from 4, 5, 6 V, and frequency from 15, 30, 45 kHz. With a water supply around it and copper coil wrapping on the outside circumference, the die was ready for the refining process. The refining process focuses on the alloying components Si, Fe, Cu, Zn, Mg, Ni, and Cr. Analysis of variance (ANOVA) is a statistical approach for determining the best level of variables for the verification of the optimal design parameters through confirmation tests. It is a decision tool for identifying the variation of process parameters. The goal of this research is to use vibration to improve tensile strength, hardness, and grain size refinement.
