A fabrication technique for 3D metal microstructures using hybrid process integrated micromachining and welding on a workstation is described in the paper. The system uses a micro-EDM (micro electro-discharge machining) process to fabricate microparts, and Nd-YAG laser welding to microassemble these microparts precisely. A diverse pattern of 3D metal microstructures or micromoulds can be attained via further machining procedures controlled by a CAD/CAM path after assembling. Since the product is completed in one integrated manufacturing process, some particular problems resulting from their small dimensions can be overcome, e.g. their high failure sensitivity, and the required micro-precision in the microassembly process. Using these procedures, diverse patterns, and high aspect ratios and high joint strength microstructures can be created precisely.To illustrate the microassembly strategies and procedures, a diverse pin-plate metal microstructure has been used and discussed in the study. It requires that the perpendicular tolerance between pin and plate, and the parallel tolerance between pins are good, and the twisting strength at the joint is strong. A diverse feature on the top of the pin was then further machined as a square, or hollow construction having an equiangular partition.

“…After this research was lost, micro-EDM started to evolve purely in the field of small-hole making (Kagaya 1986, Sato 1986, and Masuzawa 1989. While small steps were taken at improving these hole-drilling machines, a major step was taken toward improving micro-EDM as a process with the advent of wire-electro discharge grinding, or WEDG (Masuzawa 1985(Masuzawa , 1986).…”

“…With this pulse generator however, when water is used as the dielectric liquid, since mono-polar high voltage is applied to the working gap to ignite the discharge, leak current easily flows through the working gap. As a result, machining accuracy drops due to electrolytic dissolution of the workpiece, although use of water is profitable for higher material removal rate (2) .…”

This paper describes the machining characteristics of electrolysis-free micro EDM in water using the electrostatic induction feeding method. With the electrostatic induction feeding method, if deionized water is used for the working liquid, electrolysis can be prevented because bipolar voltage is applied to the working gap. Results of micro-holes drilling showed that the material removal rate with deionized water is higher than that with oil, and the oversize of holes machined in deionized water is smaller. Moreover, micro-holes could be drilled successfully even in a tap water with the oversize of several micrometers using this method.
