Parametric study of electrochemical discharge drilling on ceramic material using Taguchi method

Pawar P., Kumar A., Ballav R.

Journal of Mechanical and Energy Engineering

Vol. 2, No 3

193--200

The Electrochemical Discharge machining (ECDM) is a hybrid machining technology which is combined with electro discharge machining and electrochemical machining process. In this research, electrochemical discharge drilling operation is carried out on conventional ceramic tile by using a designed and manufactured ECDM setup. The experiments were performed as per design of experimental technique of Taguchi L27 orthogonal array using MINITAB 17 software. The important process parameters that have been selected are voltage, rotation and electrolyte concentration with output response as machining depth and diametric cut. From the observations, it is found that the voltage is the most significant parameter for the machining depth and diametric cut followed by electrolyte concentration and rotation.

Development and manufacturing of Arduino based electrochemical discharge machine

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.
