Investigation on the surface roughness of the high steel material after wire electrical discharge machining process

Abstract

At present, Wire Electrical Discharge Machining (WEDM) is a widespread technique used in industry for high-precision machining of all types of conductive materials such as metals, metallic alloys, graphite, or even some ceramic materials, of any hardness, WEDM is employed in a wide range of industries, including aerospace, biomedical, automotive, as well as die and mould. This study presents the investigation of various WEDM process parameters such us pulse on time (TON), Servo Voltage (SV) or U and peak current (I) on Surface Roughness (SR) or Ra of high alloy steel X155CrMoV12, and to obtain the optimal settings of machining parameters which the Surface Roughness is minimum in a range. We used Taguchi's design experiments methodology for planning and designing the experiments. The results from this paper will be useful for manufacturing engineers to select appropriate set of process parameters to machine AISI D2 steel. (C) 2017 The Authors. Published by IASE.
