“…The maximum cutting speed of AlSi7Mg/SiC and AlSi7Mg/Al 2 O 3 composites are approximately 3 times and 6.5 times lower than the cutting speed of aluminum alloy, respectively. Guo et al (2002) studied the machineability of Al 2 O 3 particle-reinforced 6061 Al-alloy by WEDM process. A method of orthogonal design has been used to determine the main factors that affect the machining process.…”

“…Over the years, the role of ceramic reinforcement on the machining performance such as surface quality, cutting rate and process has been identified (Guo et al, 2002;Srivastava et al, 2014;Sharma et al, 2014). According to , during the WEDM of MMCs, wire breakage occurs when the wire comes in contact with non-conducting ceramic particles.…”

Abstract:Wire electrical discharge machining (WEDM) is a widely employed non-traditional machining process. Metal Matrix Composites (MMCs) are newly developed materials having favourable mechanical properties like high strength, hardness, wear resistance and strength to weight ratio. In this study, experimental investigation based on the Taguchi method involving four control factors with three levels using orthogonal array L18 is reported. Taguchi orthogonal array was used to study the effect of combination of reinforcement, pulse on-time, off-time and servo voltage on Material Removal Rate, kerf width and surface finish. A6061 and A6061/Al 2 O 3 /10 p have been machined in this study. The wire electrode breakages were found during the machining A6061/ Al 2 O 3 p composite. The locations and frequency of wire breakage was studied to identify the reasons of wire breaking during machining of these materials.

“…An experimental investigation for Wire EDM of Al 2 O 3 particle reinforced material (6061 alloy) has been performed by Z.N.Guo et al [2] It was concluded that In operation, a large pulse duration, a high voltage, a large machining current and a proper pulse interval should be selected for getting high machining efficiency.An experimental investigation have been performed by P. SrinivasaRao et al [3] for finding machining accuracy on wire cut electrical discharge machining of Inconel 75 material of thickness 5mm to 90mm in different sizes.A series of experiments have been performed for finding the effects of cutting parameters on surface roughness in the WEDM process by Mustafa IlhanGokler et al [4] on 1040 steel material of thicknesses 30, 60 and 80 mm, and on 2379 and 2738 steel materials of thicknesses 30 and 60 mm. Aqueel Shah et al [5] investigated the effect of work piece thickness, open voltage, pulse on time, pulse off time, servo voltage, wire feed velocity, wire tension, dielectric pressure on the material removal rate, kerf, and surface roughness for wire EDM of WC-10%Co composite, it was expected that this factor was a significant one while according to this research work piece thickness is not a significant factor for material removal rate.S.…”

Abstract-Among various material removal processes, Wire-EDM is considered as an effective process for the machining of modern composite materials. Its inherent capability for automation is another feature which fulfils the expectations of modern manufacturing industries. Wire-EDM is a complex machining process controlled by a large number of process parameters. In the present study an attempt has been made to find the effect of process parameters such as peak current, pulse on time, pulse off time, workpiece thickness and wire feed rate over different machining performance characteristics such as cutting rate, surface roughness and wire wear ratio. Taguchi based L 27 orthogonal array has been used for conducting experiments. Analysis of variance (ANOVA) technique was used to find out the variables affecting the performance characteristics. A mathematical model has been developed for each machining performance using reweighted least square method to create relationships between process factors and responses. Results from the analysis show that the workpiece thickness, pulse on time and peak current are the most effective parameters affecting the cutting rate, surface roughness and wire wear ratio respectively.
