High surface quality and/or dimensional accuracy of the products produced by machining plays an important role in part performance. The use polymer materials is gradually replacing that metallic materials. Due to their anisotropy and non-homogeneity, behavior differs greatly from normal Because phenomena responsible for material removal while cutting fiber reinforced plastic composite those typ...

In this present investigation, the effect and optimization of machining parameters on the kerf width and surface roughness in wire electrical discharge machining (WEDM) operations of Al 60661 hybrid composite was studied. The hybrid metal matrix composite was fabricated by stir casting process using particulates SiC and graphite each in Al6061 alloy. The experiments were designed with L27 ortho...

With respect to multiple attribute decision making (MADM) problems in which the attribute values take the form of hesitant fuzzy elements, the traditional grey relational projection (GRP) method is extended to solve multiple attribute decision making problems under hesitant fuzzy environment. Based on the hesitant fuzzy decision matrix provided by decision makers, all feasible alternatives are ...
