EFFECT OF PROCESS PARAMETERS OF WEDM ON SURFACE ROUGHNESS AND MATERIAL REMOVAL RATE FOR ALLOY MATERIAL (AL6101-T6) USING TAGUCHI METHOD

WEDM (Wire Electric Discharge Machining) process is used to cut conductive metals of any hardness. The process is specialized in cutting complex contours or fragile geometries that would be difficult to be produced using conventional machining process. The literature review has revealed that very less research work has been done in order to achieve optimal levels of process parameters for alloy material AL6101-T6 using zinc coated brass wire electrode. The objective of the present research work is to study the effect of different process parameters viz. pulse on time, pulse off time, servo voltage and wire feed rate on the response parameters viz. material removal rate, surface roughness using 0.25 mm diameter zinc coated brass wire. Taguchi design methodology has been chosen for design of experiment and L9 orthogonal array (OA) has been selected for present study.
