Digraph and matrix method to evaluate the machinability of tungsten carbide composite with wire EDM

摘要: Machinability aspect is of considerable importance for efficient process planning in manufacturing. an engineering material may be evaluated terms the output variables like removal rate, processed surface finish, cutting forces, tool life, specific power consumption, etc. In this paper, graph theoretic approach (GTA) proposed to evaluate machinability tungsten carbide composite. Material rate considered as a attribute effect several factors and their subfactors. Factors affecting interactions are analyzed by developing mathematical model using digraph matrix method. Permanent function or index obtained from developed digraphs. This value helps quantifying influence on machinability. present illustration, grouped into five broad namely work material, machine tool, electrode, conditions, geometry machined. GTA methodology reveals that has highest value. Therefore, it most influencing factor
