The objective of the present work was to investigate the effect of the wire electrical discharge machining process parameters on material removal rate of titanium alloy using Taguchi approach. A brass wire of 250μm was applied as a tool electrode to cut the specimen. L36 mixed orthogonal array (2 ×3) has been selected for experimentation under different variables like dielectric conductivity, p...

Abstract Electrical discharge machining (EDM) is one of the most widely used non-conventional methods to machine electrically conductive materials in manufacturing industry because its strong capability difficult-to-cut irrespective their strength and hardness. drilling (EDD) an important variant EDM. Due limitation conventional processes, special holes, particular those with high aspect ratios...

This study investigates the effects of cutting parameters on surface roughness (Raμm ), cutting temperature (T0C) at the chip tool interface and the material removal rate (MRR mm3/min) during hard machining of AISI 1015 (43 HRC) steel using carbide insert under dry and spray impingement cooling environment. A combined technique using orthogonal array and analysis of variance (ANOVA) was employe...

The objective of the present study is to optimize the process by applying the Taguchi method with orthogonal array robust design. Taguchi Parameter Design is a powerful and efficient method for optimizing the process, quality and performance output of manufacturing processes, thus a powerful tool for meeting this challenge. Off-line quality control is considered to be an effective approach to i...

The optimization of parameters considering multiple performance characteristics of the EDM process for SS 304 using the GRA is presented. Performance characteristics including MRR, TWR, and OC are chosen to evaluate the machining effects. Those process parameters that are closely correlated with the selected performance characteristics in this study are the pulse-on time, current, and voltage. ...

In this study, the influence and optimization of the factors of a non-formaldehyde resin finishing process on cotton fabric using a Taguchi-based grey relational analysis were experimentally investigated. An L27 orthogonal array was selected for five parameters and three levels by applying Taguchi's design of experiments. The Taguchi technique was coupled with a grey relational analysis to obta...

Titanium alloys are extensively used in aerospace, missiles, rockets, naval ships, automotive, medical devices, and even the consumer electronics industry where a high strength to density ratio, lightweight, corrosion resistance, resistance temperatures important. The machining of these has always been challenging for manufacturers. This article investigates combined effect radial depth, cuttin...

The present research used the stir-casting method to develop an Al-based composite. developed composite exhibited challenges while being processed on conventional machining. Thus, a non-traditional machining process was opted variables selected for current were pulse off time (Toff), (Ton), servo voltage (SV), (I), and tool electrode. Three electrodes (SS-304, copper, brass) (Al/SiC/Gr). experi...
