原始语种摘要: Tungsten carbide-cobalt composite (WC-Co) is commonly considered a difficult to machine material due to its very high hardness. High strength and wear resistance make WC-Co a preferred material for manufacturing of tools, dies, and molds, etc. All such applications require complex shapes to be machined including curved features. The present study is carried out to evaluate the potential of wire electric discharge machining (WEDM) to fabricate concave and convex curved profiles of different radii in WC-Co. Taguchi design of experiments technique has been employed to investigate the influence of six control variables including open circuit voltage, pulse-on time, pulse-off time, servo voltage, wire tension, and dielectric pressure, on two response characteristics namely radius of concave...
