correct selection of manufacturing condition is one of the most important aspects which should be considered in the majority of manufacturing processes,  particularly in the process related to advanced machining process like electrical discharge machining. in electrical discharge machining (edm), dielectric fluid plays an important role since machining characteristics are greatly influenced by ...

The correct selection of process parameters for manufacturing is one of the most important aspects taken into consideration in the majority of manufacturing processes and particularly, in process related to EDM. The machining characteristics are greatly influenced by the nature of dielectric used during micro-EDM. The present paper investigates the fuzzy logic model for micro-electrical dischar...

-AISI D3 tool steel is a high-carbon, highchromium, oil-hardening tool steel that is characterized by a relatively high attainable hardness and numerous, large, chromium-rich alloy carbides in the microstructure. These carbides provide good resistance to wear from sliding contact with other metals and abrasive materials. Typical applications for D3 tool steel include Blanking, stamping, and col...

The aim of this paper was to study the effects of die life through shot peening treatments on AISI H13 steel, and tests were performed to study the influential parameters of the shot peening process. To evaluate the effects of microstructure and the die life of AISI H13 steel after steel shot peening processes, we conducted and evaluated roughness tests, micro hardness and wear tests, and SEM m...

Mechanical properties response of extruded 6063 aluminum alloy at varied die entry angle has been investigated. Plain carbon and tool steel dies with entry angles of 15, 30, 45, 60, 75 and 90 were simulated. Extrusion on the alloy was done at ambient temperature (37C) and the extruded samples from the various angles were subjected to selected service related mechanical tests and microstructural...

Corrosive-erosive effect on AISI D3 steel, 304 stainless steel and CrN/AlN coating in aqueous NaCl slurries was studied. CrN/AlN multilayer films with a thickness of 3 m and bilayer period of = 60 nm (50 bilayers) were obtained by using the physical vapor deposition (PVD) technique (magnetron sputtering). The corrosion-erosion experiments were performed in a test machine in which the impingemen...

BACKGROUND Injection molding is an important manufacturing process for optical and mechanical components. The hard steel dies used in injection molding play a direct role in the quality of molded parts. Traditionally, fabricating the dies involved rough milling followed by heat treatment, grinding and polishing. Recently, high-speed machining of heattreated steel (hardness > 55 Rc) has become a...
