The machining of a glass material is highly complicated due to its physical as well as chemical properties. The electrochemical discharge machining is an integrated hybrid machining process which has utilized to machining of conducting materials as well as high strength non-conducting materials having brittleness and high hardness. In this research article, the electrochemical discharge machining experimental setup was built and fabricated for machining of non-conducting materials. The electrochemical discharge machining process was applied for drilling on soda-lime glass material. The experiments were done with reference to Taguchi L 27 orthogonal array approach and scrutinized by utilizing the MINITAB 17 software. The machined depth and hole diameter results were inspected after electrochemical discharge drilling on soda-lime glass material with considering the machining conditions such as voltage, electrolyte concentration, and rotation. The observation results showed that voltage is the major parameter for machined depth and hole diameter followed by electrolyte concentration and rotation of tool electrode.

The machining of non-conducting materials is very difficult due to its brittleness and hardness properties. The electrochemical discharge machining (ECDM) process is the hybrid non-traditional manufacturing technology because it is combined with two processes namely electro-chemical machining (ECM) and electro-discharge machining (EDM) which can cut non-conducting and conducting materials. Hence from this view, the present work is undertaken to understand the development and manufacturing of ECDM setup based on Arduino. The 2D drawings are drawn by using AutoCAD software and 3D model is developed with CATIA software. The ECDM machine setup is manufactured accurately according to the 2D drawings and 3D model. The gravity feed mechanism is applied to workpiece materials and the speed of cathode tool electrode is controlled by using Arduino programming through the computer. The preliminary experimental trials were carried out and micro-hole drills on the glass and ceramic materials are successfully achieved. The present article provides fundamental and detailed building study of ECDM setup which includes information from the starting sketch up to the real prototype model. This work may be useful to make advanced machining setup as well as may solve the basic difficulties of new researchers in this field.

“…During the last decades, the researchers studied especially the possibilities to use the electrochemical discharge process to machine workpieces made of insulating materials [1]; generally, the explanations concerning the phenomena occurring within the work zone and the influence exerted by different factors on the characteristics of technological interest were preferentially emphasized. Thus, Chak and Rao [2] showed that workpieces of ceramics such as aluminium oxide (Al2O3) can be drilled by the using of the electrochemical discharge process; they built a specialized machine tool destined to be used for drilling and proved that a rotary abrasive electrode can enhance the process efficiency. The analysis of some aspects specific to the electric pulses in the case of the electro -discharge -electrochemical process was made by Schulze et al [3]; they emphasized that two different processes can be successively used: a rough electrical discharge machining process with pulse currents up to 500 A and a final finishing process which uses pulse currents up to 2000 A.…”

The electrochemical discharge machining (ECDM) offers an alternative to high technology equipments for drilling of small diameter holes in the case of difficult to machine materials. For a machining system based on the semidielectric liquid use and on the electric discharges initiated by contact break-out, the weight factor of the electrodes contact period is evaluated and the weight factor of the electrical discharges during this contact period is expressed. The paper presents some geometrical considerations which permit to conclude that the material removal rate depends on the characteristics of the motion and on some dimensions of the elements belonging to the crank mechanism. The influence of the input parameters on the axial electrode -tool wear and on the drilling speed is discussed.
