“…These processes is implemented by real scaling down of the conventional structures, tools and machines with additional maintenances (K.P. Rajurkar, 2006). Micro-forming can be one of the best options in the mass-manufacture of micro-parts, where the micro-forming machine is autonomous and it is integrated with parts transport systems and high precision feeding (Akhtar Razul Razali, 2013).…”

Nowadays, there are increasing demand on micro-systems, micro products/components and micro-devices. Thus, the role of micro manufacturing in all aspects of modern industry is taken for granted. Then, typical processes in micro manufacturing are discussed. Furthermore, one of the most widespread micro-manufacturing processes in deforming processes is micro forming that is presented in this paper. Finally, besides continuing effort in developing micro forming, this paper strives to analyze systematically the key methods of stamping, bending, forging and deep drawing processes and their prominent issues.

“…In general, micro-wire, die-sinking, micro-milling and micro-drilling are the widely recognised machining methods. They can produce the feature size down to a few microns with possible aspect ratio of 100 [2]. Specifically, micro Wire Electro-Discharge Grinding (WEDG), firstly introduced by Masuzawa [9] in 1985, is also regarded as an important micro-EDM configuration.…”

“…Promising applications are not just limited to the machining of hard materials for micro-moulds, but also the production of difficult-to-make structures such as fuel injection nozzles, spinneret holes for synthetic fibres, electronic and optical devices, micromechatronic actuator parts and micro-tools for producing these devices [2]. Moreover, machinable materials are no longer restricted to high-hardness alloys or cemented carbides.…”

The Micro Electrical Discharge Machining (Micro-EDM) process has proved to be an appropriate nonconventional machining method for manufacturing accurate and complex three-dimensional structural microfeatures which are difficult to be produced by conventional processes. However, the miniaturisation of the EDM process requests special requirements on the machining equipments. Pulse generators, which can produce small input energy pulses, and high precision systems are the two major criterions. In this paper, newly developed advanced technologies regarding to these aspects are explored with the aid of a commercial micro-EDM machine. First of all, by examining the pulses, innovative strategies implemented in the pulse generator are studied. Indepth research also reveals the correlation between the discharge pulses and the machine parameters in order to provide an indicative overview of process capability. Secondly, precision machining, which is represented by producing a three-dimensional micro-structure such as a micro-compressor, is demonstrated. Accordingly, by examining the machining geometry and surface integrity, process characteristics of micro-EDM are discussed.

In this work, effect of inductance was investigated in micro EDM using high frequency bipolar pulse generator used for electrolytic corrosion prevention in deionized water. To understand behaviors of the pulses during machining according to inductance, capacitor voltage which is equal to gap voltage and inductor current were analyzed both theoretically and experimentally. Inductance affected the pulse behaviors as well as machining characteristics. In the case of high inductance, inductor current increased after discharge occurred. This increased inductor current also increased both capacitor voltage and discharge current. So, machining time decreased, and tool wear as well as side gap increased with high inductance. However, this peak value shift could lead fluctuation of gap distance and servo voltage, thus, deteriorated controllability. On the other hand, constant discharge current was achieved in the case of low inductance. Low tool wear, small side gap and fine surface were achieved with low inductance.
