The aim of present research work is to investigate the systematic literature review on optimization techniques applications in the cutting processes within the sustainable manufacturing context. Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). All rights reserved. Improving machining performance of wire. Results are validated by particle image velocimetry and high-speed camera recordings. Electrical discharge machining (EDM) is a non-traditional machining process based on removing material from a part by means of a series of repeated electrical discharges between tools, called electrodes, and the part being machined in the presence of a dielectric fluid. Firstly, the design and development of the HEDAM circuit has been discussed. Manufacturing activities and advancements indicate a countries wealth at many times.

Keyword co-occurrence is found out with the help of network analysis. 0000024927 00000 n One-third of power generation in Bangladesh depends on the expensive fossil fuels which are imported from other countries and developed nations. In Bangladesh, renewable energy share is only 3% out of its total energy consumption and production and now Government of Bangladesh is promoting the renewable energy projects in order to promote the renewable energy trend and sustainability in Bangladesh. DOI: 10.5772/7009. uBUD” GUltRAU Back to Basics In our “Letters to the Editor” department, several readers have suggested that we include a Basic EDM Theory article for the newest members of our EDM commu- nity. Electric discharge machining, also known as spark erosion, electro-erosion or spark machining is a process of metal removal based on the principle of erosion of metals by an interrupted electric spark discharge between the electrode tool cathode and the work anode. Recent advances in the technologies brought the development of new engineering materials, which are hard to machine with traditional machining processes. The development in the new hybrid techniques and new tool materials makes some new research scopes in the EDM. Finally, experimental results were reported, where holes were drilled using the developed HEDAM process. In the process, workpiece is taken as anode and tool is taken as cathode. Disadvantages of Electrical Discharge Machining: Electro discharge machining still has some disadvantages and those are: Excessive tool wear. The tool and workpiece must be electrically conductive and a small gap is maintained in between them. It has been found that the wear resistance and strength of materials can be improved by adding hard ceramic particles such as Al 2 O 3 , SiC, TiC and ZrO 2 into the metal matrix. machining is limited. manufacturing sectors. Assisted-type HMPs were developed specifically to overcome the limitations of advanced machining processes and to improve the machining quality and productivity. These days optimization with the help of traditional approaches and machine learning approaches have become popular to achieve the sustainability in the manufacturing practices. BASICS OF ELECTRICAL DISCHARGE MACHINING The origin of electrical discharge machining goes Although remarkably similar surface roughness and tool sharpness were obtained in both processes, it was found that residual stress and … Consequently, rapid tool wear during the machining of Inconel 718 results in poor productivity. In EDM, Material removal rate (MRR) Tool Wear rate and surface roughness (Ra) are important performance measures.
