Electrochemical discharge machining process is evolving as a promising micromachining process. The experimental investigations in the present work substantiate this trend. In the present work, in situ, synchronised, transient temperature and current measurements have been carried out. The need for the transient measurements arose due to the time-varying nature of the discharge formation and time varying circuit current. Synchronised and transient measurements revealed the discrete nature of the process. It also helped in formulating the basic mechanism for the discharge formation and the material removal in the process. Temperature profile on workpiece and in electrochemical discharge machining cell is experimentally measured using pyrometer, and two varieties of K-type thermocouples. Surface topography of the discharge-affected zones on the workpiece has been carried out using scanning electron microscope. Measurements and surface topographical studies reveal the potential use of this process for machining in micron regime. With careful experimental set-up design, suitable supply voltage and its polarity, the process can be applied for both micromachining and micro-deposition. It can be extended for machining and or deposition of wide range of materials.

Abstract. The Electro Chemical Discharge Machining (ECDM) is a hybridization process of electro chemical and electric discharge machining, which is used for machining of hard, brittle and nonconductive materials. The present paper investigates the effect of duty ratio at different pulse frequency on the four process responses, i.e. material removal rate, depth of penetration, surface damage and heat affected zone of the hole drilled by ECDM. The requirements of a quality drilled hole are to have less surface damage and heat affected zone along with larger depth of penetration and material removal rate. The selected alumina ceramic (Al2O3) work piece material is widely used in hi-tech electrical apparatus. The results were characterized by optical microscope and analysed by using pulse wave forms of voltage with time. The results show that the effectiveness of pulse frequency varies according to the desired response characteristics. The research findings provide the most effective duty ratio for an improved quality of drilled hole in ceramics.

“…They introduced that wire surface roughening is proposed to enhance spark discharge distribution over the tool surface and lower the working voltage. Fascio et al [12] proposed that micro fabrication of Pyrex glass is one of the key processes. Several applications need glass because of its unique properties like its chemical resistance, transparency, low electrical and thermal conductivity or biocompatibility.…”

-Electrochemical spark machining (ECSM) is hybrid machining process which is the controlled removal of metal by anodic dissolution as well as erosion in an electrolytic cell in which the workpiece is the anode and the tool is cathode. The experimental investigation with the developed TW-ECSM set-up has been needed to understand the behaviour of the process parameters on performance characteristics. One-Parameter-At-a-Time (OPAT) approach is extensively used to study the behaviour of newly developed process. This approach requires to find the suitable range of control parameters for desired outputs. In this technique, only one parameter is varied at a time in wide range while other parameters are kept at constant .In similar way, the effect of all individual control parameter on output is investigated. Epoxy glass, which is frequently used as a material for fabrication of micro structures, was used as a workpiece. In order to achieve the effective and controlled material machining, the following input process parameters are optimally controlled such as Applied Voltage, Wire velocity, Electrolyte concentration and Duty factor. The machining criteria during the TW-ECSM operation can be considered as Material removal rate (MRR).The experimental setup of TW-ECSM of the process parameters are to be properly controlled to achieve the good machining performance.
