Optimization of process parameters on wire cut electrical discharge machining and surface integrity studies of AA6070/MgO composites

Abstract There are a variety of uses for metal matrix composites (MMC), including the aerospace and automotive industries. Because their benefits light weight inexpensive cost, they popular. Wire cut electric discharge machining (WEDM) stands out as great option creating complex or complicated shapes composite materials, especially when compared to other common non-traditional processes. An AA6070 containing 5% 10% MgO fraction (wt) was made using stir casting method in this work. Various process factors, such wire tension (WT), dielectric pressure (Pd), gap voltage (Vg) peak current (IP) taken into account AMMC specimen is machined utilising WEDM. Slot rate (MR) surface roughness (Ra) can be measured assessed L18 mixed Orthogonal Array (OA) investigations. Experiments examined TOPSIS ANOVA methodologies order preference based on similarity ideal results (ANOVA). Analysis has shown that best mixture processing factors improved MR Ra: wt = 5%, vg 50 V, WT 13 g, Ip 9 A, Pd 15 bar. Machining Rate Ra have parameters 1.5 mm/min 3.648 m. shows significantly influenced by current.
