Electrochemical Spark Machining (ECSM) is applicable to machine the materials which are non-conducting. The present research work extended the application area of ECSM process from non-conducting materials to semiconducting materials i.e. silicon carbide (SiC). In order to enhance material removal rate (MRR) and to reduce the entrance oversize (OS) as well as surface roughness (SR), the magneto-hydrodynamic (MHD) convection approach is utilized. The magnetic field (MF) produces Lorentz forces during electrolysis process. This MF assisted travelling-wire electrochemical spark machining (TW-ECSM) process provides better flushing in narrow gap between work material and tool electrode by clearing the zone from debris particles to obtain a stable spark. It is evident from results that presence of magnetic field improved MRR from 19.15% to 200% and reduced SR and OS from 16.86% to 48.58% and from 11.37% to 21.27% respectively.

Mechanical erosion-based drillings are abrasive water jet drilling (AWJD) and ultrasonic drilling (USD). In these processes, materials are removed by the mechanical erosion of work material by high-pressure slurry (abrasive particles mixed with water). AWJD can produce miniature-sized holes on metallic and non-metallic materials. USD is used for machining miniature-sized holes on conductive and non-conductive materials having a hardness of more than 40 HRC. In thermoelectric erosion drilling methods, thermal energy is utilized to remove materials by melting and vaporization. These methods include ram-based spark-erosion machining (SEM), spark-erosion drilling (SED), and laser drilling. SEM and SED are used to produce miniature-sized holes on electrically conductive materials irrespective of their hardness, while laser drilling is used to produce miniature-sized holes on non-reflective metallic materials. The material removal rate in laser drilling is higher than in SED and SEM processes. The micro versions of SEM and SED are micro-spark-erosion machining (µ-SEM) and micro-spark-erosion drilling (µ-SED). Electrochemical drilling (ECD) is used to produce microholes on workpieces by ion displacement. It involves anodic dissolution where an electrolytic cell is formed by a tool (cathode) and workpiece (anode) surrounded by the continuous flowing electrolyte. In chemical drilling (CHD) methods, miniature-sized holes are produced by the chemical action of the corrosive agents.

Micro spark erosion machining (µ-SEM) is used to make a different type of microhole by using similar shapes and sizes of fabricated tool electrodes. In the µ-SEM process, the non-rotating tool electrode moves downward to make a microhole on the workpiece. Figure 1 shows the schematic diagram of the µ-SEM setup. µ-SEM has the potential to fabricate circular and non-circular through and blind microholes, such as square, rectangular, and triangular as shown in Figure 2.

The major advantages of µ-SED are (i) the ability to drill deep high-aspect-ratio (HAR) fine holes, (ii) the ability to produce accurate fine circular holes, (iii) no burr formation, thus eliminating the secondary finishing process, (iv) ability to drill high precision microscopic-holes, (v) the absence of mechanical stresses, (vi) the ability to produce holes on any kind of materials irrespective of their hardness, (vii) the ability to produce holes on thin and fragile materials; (viii) the ability to drill holes at a certain angle, (ix) the high material removal rate; and (x) unattended machining for a longer period.
