Glass has wide application in the production of micro components. Electro-chemical discharge machining (ECDM) has proven an inexpensive and potential micromachining method for such nonconductive materials. ECDM has the electro-chemical machining (ECM) and electric discharge machining (EDM) constituent processes. It overcomes limitations and provides benefits of both constituent processes, namely EDM and ECM. The major limitation in the industrial application of this technique is controlling of gas film formation and discharge activity. Researchers have attempted numerous studies, both experimental and simulation, exploring the physics behind the process. In view of appraising research carried out in recent years, the present work reports a comprehensive review of modeling and simulation studies in electro-chemical discharge machining along with a brief introduction to ECDM. Different modeling and simulation approaches applied by researchers were discussed. The importance of various simulation parameters and material removal criteria were justified.

“…[5] found the relationship between electrolyte concentration and thermal conductivity prosper, and then made a finite element model to show the same. Paul and Korah [12] did some simulations on the finite element model for pulsed spark for comparison between the MRR and maximum temperatures to get the result with that of a normal spark. Goud and Sharma [13] did finite element model by taking the calculation of the heat generation in 3-D Gaussian spark region and had a prediction of the MRR for Silica glass and alumina.…”

Electrochemical discharge machining (ECDM) is a novel technique for machining non-conductive materials like quartz, soda lime glass, ceramics etc. It combines the machining attributes of the electric discharge machining (EDM) and electrochemical machining (ECM) simultaneously in a single process. Despite numerous experimental studies, few studies are reported covering analytical aspects of the ECDM process. The present study focusses on the development of finite element based thermal model for analyzing the material removal of the different work materials. The model is validated by comparing it with existing literature and a comparison of the different models based on different heat input i.e., uniform distribution and Gaussian distribution is also performed. Results revealed that the material removal rate (MRR) predicted using Gaussian distribution exhibits fair agreement with the earlier reported results. Moreover, the comparative study on MRR is performed using gaussian heat distribution for soda lime glass and quartz material. It is observed that under similar machining conditions, MRR of soda lime glass is higher than the quartz material. The MRR of the both the work materials increases with the increase in electrolyte concentration due to increase in total heat input over the work material.

As a nontraditional processing technology, Electrochemical discharge machining (ECDM) can precisely process glass and engineering ceramics. This technology has proven to be a potential process for glass 3D microstructure. However, the key to expanding the application of ECDM is how to improve machining accuracy. This research conducted micro-hole and microgroove machining. The influence of power voltage and frequency on hole processing efficiency, hole entrance diameter and hole limit depth explored. We considered four factors affecting ECDM–the voltage and frequency of the pulse power supply, the tool electrode feed rate, and the rotation speed. We studied their influence on the roughness of the microgrooves. The results show that machining efficiency, entrance diameter and limit depth of micro-holes increased with the increase in voltage, but decreased with the increase in power frequency. The results show that the roughness of microgrooves has an obvious positive correlation with the power voltage, while it had an obvious negative correlation with the power frequency and the electrode speed. The bottom surface roughness of microgrooves can be as small as 0.605µm. Various complex 3D microstructures on the glass surface by layer-by-layer method, which proved the great potential of ECDM.
