ABSTRACT
Micro-machining is a mechanical machining process, which involves the use of several micro-tools with defined cutting edges or sometimes involves the use of laser technology, micro-EDM, etc., and having devices or features with a micrometer range (1–999 µm) of dimension in the workpiece or tool. Selecting the appropriate machining technique is the key to achieving the fineness of the machined product. EDM is a popular method for micromachining because it can machine electrically conductive materials with various hardness, strength, and temperature resistant as well as complex shapes with accurate dimensions and fine surface roughness. Moreover, this method is widely used to make micro-scale products such as micro-actuators and micro-fabricated electronic sensors. We present a comprehensive and state-of-the-art review of various new research findings in the following paper as well as the development, advancement of Micro-machining processes using EDM in Titanium Alloy starting from the various kinds of micro-electrode, work-piece materials, and dielectrics (flushing included) that have been used by previous researchers. Although electrical discharge machining (EDM) is suitable for machining titanium alloys, it is difficult to find higher machining parameters for high rates and accuracy in machining.
