Abstract: A desktop fabrication system has been developed for advanced production shops, as an advanced micro-mechanical fabrication tool for producing advanced microcomponents. In this study, we developed a cylindrical grinding machine that employs the ELID technique, for use as a microtool. We also carried out detailed investigation on the performance of the electrode turning method of the ELID system; a microcylindrical shaft and microangular shaft were ground by the cylindrical grinding machine employing the ELID technique. Good dimensional accuracy was achieved.

Keywords: cast-iron-bonded diamond wheel; cylindrical grinder; desktop fabrication system; ELID (electrolytic in-process dressing); micromechanical fabrication; microtool; plasma discharge truing.
