Grey relational analyses are applied to determine the suitable selection of machining parameters for Wire Electrical Discharge Machining (Wire-EDM) process. The Grey theory can provide a solution of a system in which the model is unsure or the information is incomplete. Besides, it provides an efficient solution to the uncertainty, multi-input and discrete data problem. According to the Taguchi...

High carbon high chromium alloy tool steels (D-3) with excellent abrasion resistance (HRC: 58-65) are increasingly used in manufacturing high performance cutting tools (dies and punches), blanking and punching tools, extrusion tools, etc. Being a hard material, it is difficult to machine using conventional machining methods. Wire Electric Discharge Machine(WEDM) seems to be a viable option to m...

Stainless steel is a material which has high corrosive resistance and oxidation at temperature with the combination of chromium, nickel, niobium as primary constituent. This difficult to machine complex shape taken by using wire cut electric discharge machining. Wire electrical machining nontraditional process widely for cutting shapes. review paper involves EDM optimization parameters. Pulse i...

Nonconventional machining technologies have been found viable to manufacture various products from a wide range of engineering materials. Wire electric discharge (WEDM), also known as Wire-EDM, is one the important thermal type nonconventional technologies. Wire-EDM being preferably used by manufacturers produce biomedical devices including bio and dental implants. This paper presents an overvi...

The operating control parameters of injection flushing type of electrical discharge machining process on stainless steel 304 workpiece with copper tools are being optimized according to its individual machining characteristic i.e. material removal rate (MRR). Lower MRR during EDM machining process may decrease its’ machining productivity. Hence, the quality characteristic for MRR is set to high...

This work attempts to optimize the multi-objective characteristics of wire electrical discharge machining (WEDM) in SLM-fabricated AlSi10Mg through a hybrid artificial neural network (ANN) coupled genetic algorithm approach. The SLM is unambiguously one most effective commercially viable successful additive manufacturing (AM) technologies that have potential replace many traditional methods man...

Wire-cut electric discharge machining is a nontraditional technique by which the required profile is acquired using sparks energy. Concerning wire-cut electric discharge machining, high cutting rates and precision machining is necessary to improve productivity and achieve high quality of machined workpieces. In this research work, an experimental investigation was introduced to achieve higher p...

Cryogenic treated high carbon high chromium alloy cold tool steels (D-3) are used in production of high performance dies, punches, blanking and punching tools, extrusion tools, etc. cryogenic treatment is a process of keeping the specimen in cold environment to increase its wear resistance and relieving its residual stresses. Due to its high hardness Wire Electric Discharge Machine (WEDM) seems...
