Book excerpt: Bachelor Thesis from the year 2017 in the subject Engineering - General, , course: Mechanical Engineering, language: English, abstract: Electric Discharge Machining is mainly used for very hard materials. Now a days we know that product and process technology is very advance, many types of new materials are being developed which have very high strength, high thermal and electrical conductivity which are difficult to machine by traditional machining methods. So Non-conventional machining methods are used to machine such type of materials, EDM is also one of the Non-conventional machining methods which is used to machine such advance hard and brittle materials to satisfy the present days product needs like aerospace, mould, dies and other applications. Mixing of powders into dielectric fluid is a one of the recent advancement in the EDM process to improve its process capabilities and is known as Powder Mixed Electric Discharge Machining (PMEDM) process. The objective of this work is mainly to study the effect of various input parameters like pulse-on-time, discharge current, tool material and grit size on the various output parameters like MRR, TWR, Surface Roughness, Hole Diameter Variation and Micro structure. In this study, these output parameters are studied by using the ANOVA through Minitab17 software. By using this software, study the Means and S/N ratios for all these parameters.

Available in PDF, EPUB and Kindle. Book excerpt: Attempt has been made to investigate the experimental process and surface roughness (SR) optimization of cold working (high carbon and high chromium) hard die steel (D2) during wire electrical discharge machining processes (WEDM). It is very difficult to determine optimal cutting parameters for improving cutting performance has been reported. Wire electrical discharge machining process relies heavily on the operators,Äô technologies and experience because of their numerous and diverse range as using complicated cuts can made through difficult to machine electrically conductive components, WEDM process was developed to generate precise cutting on complicate, hard and difficult to machine materials. Tan-sigmoid and purlin transfer functional with bias based four layered back propagation artificial neural network (BPANN) approach have been used to investigate the effect of six independent parameters namely gap voltage (Vg), flush rate (Fr), Pulse on time (Ton), pulse off time (Toff), wire feed (Wf) and wire tension (Wt) over CLA value of surface roughness (Ra) along with corresponding material removal rate (MRR). A fractional factorial design of experiment of three level were employed to conduct 80 rows of experiment on (D2) steel with chrome coated copper alloy wire electrode. The predicted response, CLA values of SR and corresponding MRR were observed by the approach of BPANN from experimental (55 rows for training, 15 rows for validation and 10 for testing) data. Software instructed programme has been used individually for training, validation and testing in MATLAB 2010a to find the corresponding prediction output. Two fold cross over technique (TFCT) were used to developed distinguish (S1 and S2) models and also developed more models depending on numbers of neurons used in primary and secondary hidden layers. The model adequacy is very satisfactory as correlation coefficient (R2) is found to be 99.1% and adjusted (Radj.2) statistics is 98.5. It is found those spark time ON/OFF, wire feed rate, wire tension, gap voltage and flush rate and few of their interactions have significant effect on SR.

This book was released on 2013 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrical discharge machining (EDM) is a process for shaping hard metals and forming deep complex-shaped holes by arc erosion in all kinds of electrical conductive materials. In the present day, there is a huge demand for the advanced materials with high strength, high hardness and temperature resistance in automobile, aeronautics, nuclear, mould and dies making industries. The purpose of this research is to study the effect of pulse duration and current on performance of EDM process of Allegheny Ludlum D2 Tool Steel (UNS T30402). The effect of varying the machining parameters on the machining responses such as material removal rate (MRR), electrode wear rate (EWR), wear ratio (WR) and surface roughness (Ra) have been investigated. In addition, this research also emphasizes on the study related to the effect of shape configuration of electrodes on the performance of EDM. The electrodes were made with circular and triangular shape with constant cross-sectional area of 100mm2. It was found that the pulse duration and current give significant effect on MRR, EWR, WR and Ra. An increase in the pulse durations causes an increase in the MRR and Ra, but a decrease in the EWR and WR. Meanwhile, the effect of currents on EDM performance shows that the increasing currents led to an increase in the MRR, EWR, WR and Ra. Finally, from all the results obtained, several analyses have been made to compare the machining performance results between circular shaped electrode and the triangular shaped electrode. It was found that the value of MRR for circular shaped electrode was higher than that of triangular shape electrode. Meanwhile, the higher value for EWR, WR and Ra was found at the triangular shaped electrode.

Download or read book ELECTRICAL DISCHARGE MACHINING PROCESS DESIGN FOR POST PROCESSING STAINLESS STEEL 316L ADDITIVELY MANUFACTURED PARTS written by Gregory Bicknell and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Wire electrical discharge machining (EDM) is a non-traditional subtractive manufacturing process. This process works by bringing a charged wire in close proximity to a conductive workpiece. When the wire is close enough to the workpiece, an electrical arc forms between the wire and the workpiece. The electrical arc melts away material from the workpiece, and the wire continues moving through the workpiece, leaving behind a slit slightly wider than the width of the wire. Wire EDM is a high-precision process that can meet very tight tolerances and is employed in several industries including the aerospace and automotive industries. Recently, wire EDM has been used in the additive manufacturing (AM) industry for metal part post-processing and removal from build plates. While wire EDM is increasingly being used in the AM industry, very little research has been conducted on the wire EDM of additively manufactured parts. This thesis discusses three studies performed on the wire EDM of additively manufactured stainless-steel 316L parts. The first study is a comparison of wrought and AM stainless-steel 316L with respect to the wire EDM process. This research tested and optimized different wire EDM process parameters for the machinability of wrought and AM 316L. The second study explored the interaction between the wire EDM process and AM stainless-steel 316L lattice support structures. Selected EDM parameters were measured while machining the support structures, and optimal support structure designs were identified for AM part removal from build-plate via wire EDM. The final study explored the interaction between the wire EDM process and stainless-steel AM parts containing pockets of trapped, un-melted powder. This study optimized wire EDM process parameters for machining trapped powder pockets and outlined a potential explanation for the high incidence of wire breakage that occurs when machining through pockets of trapped powder.
