Abstract:
Wire electrical discharge machining (WEDM) is a specialized thermal machining process, capable of accurately machining parts with different hardness, complex shapes and sharp edges that are very difficult to be machined by the traditional machining processes. The practical technology of the WEDM process is based on the conventional EDM sparking phenomenon utilizing the widely accepted noncontact technique of material removal.In this paper, the effects of various process parameters of WEDM like pulse on time (Ton), peak current (IP), wire feed (WF) and wire tension (WT) have been investigated to study their impact on wear of wire of ELECTRONICA SPRINTCUT WEDM machine.It is found that the wear is influenced with increase in pulse on time (Ton) and wire tension.

Abstract:
It is well kown that the wire electrode is flexible and will lead to a big lag in wire EDM machining, especially in the middle area of the work-piece. Methods to measure the wire deflection when it passes through the work-piece are studied in this paper. It is found that there is discharge spark first at the upper and lower parts of the wire when it cuts to the edge of the work-piece. The discharge spark appears at the middle of the work-piece a few seconds later. Based on this result, a method coined Camera Picture Analysis (CPA) is proposed to estimate the wire deflection. Another method of cross section measurement by the CCD is proposed to make a cross reference with the CPA method. By applying these two methods, the wire deflection models can be established, and used for the corner cut control of wire-cut EDM to improve accuracy of the machined parts.

Abstract:
Non-traditional machining processes are popular for generating complex features on the work piece. With advances in material engineering, new ways of cutting technologies has been emerged. However, EDM (Electric Discharge Machining) has gained recognition for producing extraordinary surface finished, intricate part geometries with accuracy and its ability to cut through difficult to machined materials. However, like every product cycle, manufacturing processes also require energy to convert raw materials into finished product. In manufacturing operations, energy input gives carbon footprints which have an effect on our environment. It is observed that reducing energy consumption is becoming the main concern of manufacturers because of enforcing environmental laws and due to the economics of the processing. It is argued that world’s 70% of energy consumption is consumed by manufacturing sector. The aim of the work was to identify direct energy demands in wire cut EDM. The variability in energy demand was explored by operating wire cut EDM at no-load and loaded conditions.Stainless steel S304 was used as a work piece. Experiments were performed on three different wire-cut EDM.Molybdenum wire, brass wire and copper wire were used as an electrode wire and distilled water was used as a working fluid. During the experiment, electrical current was measured and the variation of power requirement was evaluated. Power required by different features of EDM was compared with the existing energy models and factors were identified that consume most of the electrical energy. Further, a comparison is made between traditional and non-traditional machining processes. This contribution will help to assess energy efficiency of EDM technology and identify priority areas for improvements. This work is also significant for machine tool designers for optimum utilization of energy,reduced environmental impact and reduced production cost of their machine tool.

Abstract:
Novel techniques are being focused on the enrichment of the performance characteristics under different machining processes. Cryogenic is one of such novel practices that tunes the surface integrity with vast variations with the traditional machining processes. Dimensional accuracy, surface roughness, material removal rate with less reduction in scrap of material is one of the prior targets of production process. Wire cut Electro Discharge Machining (WEDM) is one method that satisfy with upgrading performance characteristics. In order to step-up these performance characteristics in attaining superior quality, cryogenics practices have collaborated with the WEDM process. Present paper deals with the reviews of the researchers that have been performed over cryogenic treated WEDM process. Effect of performance characteristics like pulse on, pulse off, current, voltage, wire tension, wire feed is discussed with relation to material removal rate, tool wear rate and surface roughness evolved. Key concept of paper is to include the research ideology with best feasible techniques that can prevail in production practice in order of contribute to the forthcoming researches in industrial and production departments.

Abstract:
Wire Electric Discharge Machining (WEDM) is one of the greatest innovations in the tooling and machining industry. This process has brought dramatic improvements in accuracy, quality, productivity and earnings. Before wire EDM, costly processes were often used to produce finished parts. Now with the aid of computer and wire EDM machines, extremely complicated shapes can be cut automatically, precisely and economically even in materials as hard as carbide. The selection of optimum machining parameters in WEDM is an important step. Improperly selected parameters may result in serious problems like short-circuiting of wire, wire breakage and work surface damage which is imposing certain limits on the production schedule and also reducing productivity. The objective of the present work is to investigate the effects of the various Wire cut EDM process parameters on the surface quality, maximum material removal rates and obtain the optimal sets of process parameters so that the quality and MRR of machined parts can be optimized. Experiments will be conducted on the pieces by parameters. The material used for machining is Aluminium alloy. The process parameters considered are Pulse Time on, Pulse Time off, Input Power, Wire Feed, Servo Voltage and Wire Tension. The optimization will be done by using Genetic Algorithm. The above work is performed in English at WinWill Technical Services, located in Hyderabad, India, for a period of 4months.

The paper has presented a novel process to reduce the thickness of metal wire. The thickness required can be obtained through adjusting the interval between rollers, it shows that the thickness can be reduced as low as 20μｍ﹐and the strength of the electrode can be still kept like as the raw material. A practical application cutting a micro slit can be obtained through the wire-cut EDM when the metal wire rolled is used as the electrode. We compare the manufacturing of EDM among rolled 30μm copper wires, ψ30μm AP lines, and ψ30μm tungsten lines. The flat copper wires possesses advantages such as thick material, big energy superiority, parameter electric discharge, and high recover of wire tensity. However, there are some problems like the escape of chips, and the carbon deposition because of the flat surface and shaking. Rolled 30μm copper wires is able to put electric wire in a minimum 32.5μm width, and set wire-cut EDM freely cutting in various angles.

Improvement of the machining performance of the taper-cut machining process of the wire —EDM is studied, in a hope that higher machining speed can be obtained by way of adjusting the tension of the wire. Most of the studies to date regarding the taper-cut machining are aimed at modifying the mechanism of the wire—EDM machines, in an effort to have the upper and lower guides of the wire concentrically aligned so that the machining fluid, i.e. water, can be easily infused into the discharge area to overcome the insufficiency of the flushing of the fluid and therefore a higher machining speed can be applied. However, for the traditional wire-EDM machines of which the structure and mechanism are unlikely to be modified, it is necessary to investigate other possible approaches for reaching higher the machining speed. In this study, a stand-alone electronic system for discriminating the discharge pulses into two categories — short and normal sparks - is devised in the first place. The percentage of the short sparks against the total discharge pulses, also known as the “short ratio”, is introduced as an index of the machining performance. The lower short ratio implies the more favorable performance. Based on the analysis of pulse trains under various machining conditions involving different wire tensions, water flushing pressures, work piece thickness, the rule for adjusting the tension of the wire in order to have favorable machining speed, in accordance with different inclining angles of wire, is obtained. In addition, a regression equation in which the wire tension, the wire angle, the work feed rate and off time are set as the four variables while the short ratio as the dependent, is established. With the assistance of the equation, short ratio, can be estimated under any given values of the three variables, without the need of the discharge pulses discriminating system said above. In the end, this paper also proposes a control strategy for taper-cut machining process of wire-EDM so as to develop a real-time on-line discharge pulses monitoring system.

WEDM is used in mold, aerospace, medical equipment and other industries, and WEDM from the hardness and toughness of the material, as long as the workpiece can be conductive can use WEDM processing , So the application of the industry is quite extensive, but because the WEDM to set the parameters and more complex, whenever the manufacturers to develop new discharge circuits or models, need to spend a lot of manpower and time to find the different line electrode diameter and Different materials suitable for the combination of parameters. 　　Therefore, this study mainly develops the software of parameter optimization system, so that when we find the parameters, we can not experiment with each condition. In addition to developing the system software, this study also reduces the number of experiments by uniform design. Select the parameters of the level, the scope is also wide, so that the prediction of processing characteristics and optimize the processing parameters part is not limited to a certain range, hoping to allow users to spend a lot of manpower and resources can be optimized parameters to find Out.

This paper presents a pulse generator for finish cutting of polycrystalline diamond (PCD) by micro wire-EDM to obtain a high-quality surface. An improved fixed pulse width modulation (FPWM) pulse control method is proposed to generate high-frequency and short-duration pulse control signals with a period of off duty cycle for reionization of the dielectric in the spark gap so as to reduce the consecutive occurrence of short circuits. Compared to the improved AC method, the improved FPWM pulse control method could provide smaller peak current and shorter discharge duration and thereby achieving smaller damaged layer and better surface finish. Experimental results demonstrate that the developed pulse generator can enable a prototype micro wire-EDM machine to achieve a surface finish as low as 0.3 μm Ra and a damaged layer as small as 1 μm on machined surface of boron-doped PCD (BD-PCD) through one roughing and three finishing operations.

Wire-EDM is a very important manufacturing process in mold industry and it is for the best choice for high hardness material and high-precision requirement. The research in line cutting optimization parameters is numerous, but in-depth explorations in the optimization of maching number are few, so in this research parameters optimization experiment for Wire-EDM second blade machining process is planned and designed. The study adopted a two-stage experiment. The first part uses Two-Level Fractional Factorial Design for factor screening, followed by experimental analysis to identify the more significant factor and finally the application of Response surface methodology (RSM) and Face-Centered Central Composite Design (FCCCD) to assess the inter-important factor by screening the expected range and the level of quality of response characteristics. The latent interference factor will affect the results, though this study adopted the randomized design, but the interference factor is unknown and cannot control or known to be controlled. This study configures Balanced Incomplete Block Design (BIBD) techniques to deal with the elimination of interference factors during the experiment and the trend effect, while obtaining optimization parameters for the wire-cut electric discharge machining process. Control facfor of this study: the open circuit voltage, short circuit discharge time, discharge time, short rest time, rest time, a servo reference voltage, the feed rate and the wire tension along with the experiments to explore the quality characteristics of the surface roughness, dimensions and processing time. After the completion of the experiment and verified with K340 die and steel Wire-EDM, the optimized processing parameters were open circuit voltage of 7 V, discharge time of 1 , short rest time of 15 s, servo reference voltage of 40 V, feed rate of 12 and the thread tension of 8 g. For the working environment at room temperature of 34 ℃, the optimized quality characteristics was the surface roughness of 2.3 , for the size of 10 mm and the required precision machining time was 194 sec. In the working environment with the standard ambient temperature of 25 ℃, the optimization quality characteristics was the surface roughness of 1.92 for the size of 10 mm and the required precision machining time was 186 sec.

Abstract:
Exposure therapy is a core component of evidence-based treatments for eating disorders (EDs), including cognitive-behavioral therapy and family-based treatment. Despite this, existing treatment guides give relatively limited attention to the clinical issues associated with good implementation of exposure. This book is designed to augment a wide variety of treatment manuals by providing ED clinicians with practical advice for maximizing the effectiveness of exposure, regardless of which evidence-based treatment they use or the profession to which they belong. Written in an easy-to-understand format, this book not only translates the most up-to-date empirical research on exposure for EDs, it also extrapolates clinical advice from the anxiety disorders literature to help busy clinicians become more effective in treating EDs. Readers will walk away with a solid foundation in the theoretical underpinnings of exposure therapy, as well as an understanding of how to utilize this information to sell the rationale for exposure to their ED patients. Clinically rich chapters, with ample case material, demonstrate how to prepare to embark on exposure therapy with a wide range of ED patients, including those with anorexia nervosa, bulimia nervosa, binge-eating disorder, and avoidant/restrictive food intake disorder. Specific types of ED exposure are covered in detail, including exposure to food and eating, cue exposure for binge eating, weighing and weight exposure, body image exposure, emotion and interpersonally focused exposure, and novel forms of exposure for EDs. Clinicians also will walk away with strategies for overcoming obstacles to implementation of exposure therapy, including institutional resistance.

Abstract:
An important electro-thermal process known as wire electrical discharge machining (WEDM) is applied for machining of conductive materials to generate most precisely. All cutting inaccuracies of WEDM arise out of the major cause of wire bending. At the time of cutting a sharp corner or cut profile, bending of the wire leads to a geometrical error on the workpiece. Though this type of error may be of a few hundred microns, it is not suitable for micro applications. In this research study, an experimental investigation based on response surface methodology (RSM) has been done on wire EDM of Aluminium 6061 t6 alloy. This chapter studies the outcome of input process variables (i.e., wire feed rate, pulse on time, pulse off time, and gap voltage) on machining output responses (i.e., corner inaccuracy) extensively. Experimental validation of the proposed model shows that corner inaccuracy value may be reduced by modification of input parameters.

Abstract:
Inconel 718 superalloy finds wide range of applications in various industries due to its superior mechanical properties including high strength, high hardness, resistance to corrosion, etc. Though poor machinability especially in micro-domain by conventional machining processes makes it one of the “difficult-to-cut” material. The micro-electrical discharge machining (µ-EDM) is appropriate process for machining any conductive material, although selection of machining parameters for higher machining rate and accuracy is difficult task. The present study attempts to optimize parameters in micro-electrical discharge drilling (µ-EDD) of Inconel 718. The material removal rate, electrode wear ratio, overcut, and taper angle have been selected as performance measures while gap voltage, capacitance, electrode rotational speed, and feed rate have been selected as process parameters. The optimum setting of process parameters has been obtained using Genetic Algorithm based multi-objective optimization and verified experimentally.

Abstract:
Abstract Nickel-based alloys represented by Inconel are materials with excellent high-temperature characteristics, and are widely used in the aerospace industry, such as aircraft and rocket engine parts. On the other hand, it is known as a typical difficult-to-cut material. Furthermore, in machining and electric discharge machining (EDM), the machining speed is slow and tool or electrode wear is a big problem. Meanwhile, electrochemical machining (ECM) using electrochemical reaction is not affected by the hardness of the material, does not generate a heat-affected layer on the workpiece surface, and has no tool wear. So, it is considered that ECM is suitable for machining difficult-to-cut materials. Therefore, in this study, focusing on the nickel-based alloy Inconel718 (Alloy718), we conducted a machining experiment using NaNO3 aqueous solution by wire ECM using a thin wire (mainly tungsten) as a tool electrode, and investigated the ECM characteristics. Wire ECM can be machined like wire EDM, and high-efficiency machining is possible by using a pulse power supply. As a result, it was found that increasing the voltage, electrolyte concentration, electrolyte supply pressure, and diameter of wire increases the current flowing between the electrodes and has the effect of promoting machining. In addition to simple cutting, the possibility of being effective not only for grooving but also for cutting complex shapes was shown.

Abstract:
Abstract. In this paper, helium-assisted near-dry wire-cut electrical discharge machining (NDWEDM) method molybdenum wire has been used to reduce the environmental impact and to cut M2-HSS material. The pressurized non-reacting helium gas mixed with a small amount of water (Helium-mist) is used as the dielectric fluid to accomplish adequate cooling and flush-out debris. The new experimental setup has been developed to conduct the near-dry WEDM tests using the L9 orthogonal array of the Taguchi technique. The input parameters such as voltage (V), pulse-width (PW), pulse-interval (PI), and flow rate (F) of mixing water and output variables are the material removal rate (MRR) and surface roughness (Ra). It was observed that MRR and Ra are amplified by the rise in voltage and pulse-width, and flow rate conversely, the pulse interval minimizes the responses. The percentage of contribution of pulse width, voltage, pulse interval and flow rate are 24.06%, 32.98%, 12.75% and 30.21% on MRR and 20.94%, 22.22%, 47.86% and 8.97% on Ra respectively. Finally, the confirmation trials have been accomplished to validate the foreseen best parameter sets on optimal responses.

Abstract:
Wire-cut Electro Discharge Machining (WEDM) is a special form of conventional EDM process in which electrode is a continuously moving conductive wire. The present study aims at determining parametric influence and optimum process parameters of Wire-EDM using Taguchi’s Technique and Genetic algorithm. The variation of the performance parameters with machining parameters was mathematically modeled by Regression analysis method. The objective functions are Dimensional Accuracy (DA) and Volumetric Material Removal Rate (VMRR). Experiments were designed as per Taguchi’s L16 Orthogonal Array (OA) where in Pulse-on duration, Current, Pulse-off duration, Bed-speed and Flushing rate have been considered as the important input parameters. The matrix experiments were conducted for the material Oil Hardened Non Shrinking Steel (OHNS) having the thickness of 40 mm. The results of the study reveals that among the machining parameters it is preferable to go in for smaller pulse-off duration for achieving over all good performance. Regarding MRR, OHNS is to be eroded with medium pulse-off duration and higher flush rate. Finally, the validation exercise performed with the optimum levels of the process parameters. The results confirm the efficiency of the approach employed for optimization of process parameters in this study.
