Wire Electric Discharge Machining (WEDM) is a promising alternative to cut the complex features like angular and curved features. INTRODUCTION Wire electrical discharge machining (WEDM) is a specialized thermal machining process capable of accurately machining parts with varying hardness or complex shapes, which have sharp edges that are very difficult to be machined by the main stream machining processes. Cutting of very thin workpieces using WEDM presents a difficulty in terms of machining stability, and requires careful consideration of machining parameters. This paper discusses the optimization of parameters of a process in WEDM machining with the application of the desirability approach on the basis of response surface methodology (RSM). Due to the absence of physical contact of tool • WEDM process can be applied to all electrically conducting metals and alloys irrespective of their melting points, hardness, toughness or brittleness. © 2018 The Author(s). Significant technological advancement of wire electrical discharge machining (WEDM) process has been observed in recent times in order to meet the requirements of various manufacturing fields especially in the production of parts with complex geometry in precision die industry. The wire-cut electrical discharge machining of D2 steel as per the design of experiment (DOE) is done on (make: ELPULS-12) WEDM machine shown in Fig. However, it may be useful in machining MMCs (such as polycrystalline diamond), which are usually hard to process with WEDM. A parametric optimization using Taguchi method: effect of WEDM parameters on surface roughness machining on Inconel 825. 3.The electrode wire used in WEDM plays a crucial role in the performance of WEDM process, brass as the wire material is used extensively for WEDM .Wire electrode used is a brass wire of 0.25 mm diameter. Wire Cut EDM Applications Because of its versatility, manufacturers use EDM wire cutting machine operation for an extensive range of applications. A majority of this process is dedicated to machining steel. Elixir Mechanical Engineering, 43, 6669-6674. The abrasion can negatively affect the machining performance, which makes such … It is familiar for its standout features on machining 2D and 3D profiles with sharp corners and low residual stresses even for higher thicknesses [1, 2]. G. WEDM applications in industry Dies and punches for Electronic and hierological components.

Abstract- Wire electrical discharge machining (WEDM) is a non-conventional machining method used to cut hard to machine material, which are difficult to process by conventional processes. In present day manufacturing industries playing the major role in the machining of new materials with complex shapes, intricate structure and difficult profiles. Optimization of process parameters of wire electrical discharge machining using fuzzy logic integrated with Taguchi method. Since the process can work for precise items, it is the ideal choice for the production of highly detailed & delicate items that would otherwise be too difficult for other machining options. Thus it is possible to increase the productivity of gear production with WEDM, while maintaining good surface characteristics. The quality of machining through process parameters on the responses in wire electrical discharge machining (WEDM) is studied. Wire electrical discharge machining (WEDM) is one of the non-conventional machining processes which is a non-contact type process, where the material is removed with the help of high frequency sparks generated between the tool and workpiece [12]. In this research paper the review of WEDM has Even though up-to-date CNC-WEDM machines are available, the problem of selection of cutting parameters in WEDM process is not fully solved, since so far there is no established standard method for predicting machining rate based on the input parameters because of … Due to its ability to cut complex shapes without the set-up times of conventional processes, wire electrical discharge machining (WEDM) lends itself to the prototyping or limited-run production of miniature gears with a low aspect ratio for use in small mechanisms.

Fig. Wirecut electrical discharge machining (WEDM) is highly precise thermoelectrical process and is considered ideal for machining very hard materials, intricate geometries and tooling. Analysis of Variance (ANOVA) has been used to determine the importance of independent variables on the desired dependent variables. Material removal rate and overcut are the desired performance measures considered in this analysis. ScienceDirect ® is a registered trademark of Elsevier B.V.

The recast layer was investigated by polishing and etching, then measuring the depth using optical microscopy and a scanning electron microscope (SEM). The recast layer that occurs in WEDM affects both the geometrical accuracy and hardness properties of the gears. The results indicate that the depth of the recast layer can be reduced while maintaining a good material removal rate, by removing only the recast material with the second pass. Wire Electrical Discharge Machining (WEDM or Wire EDM) is one of the advanced method used for material removal process and greater in familiarity that employed in numerous engineering applications for producing various intricate shapes such as turbine blades, nozzles for fuel injectors, etc., The WEDM technique has become a leading non-traditional machining process to cut geometrically complex and intricate profile materials used in aerospace, nuclear, military, chemical, electronic, medical, automobile and manufacturing industries,,. Inconel 625 is one among the hard to machine material and extensively used in high temperature applications. The production of very accurate, low aspect ratio gears is difficult in WEDM because the limited area for spark generation between wire and workpiece leads to unstable machining, resulting in poor machining rate and surface finish.
