Abstract
In this paper a multi-function high precision tabletop CNC machining center formaking micro parts is developed. All the needed machining processes can be carriedout on the same machine without the need to unload, reload and eadjust the workpiece for subsequent process. Currently the functions of Micro CNC milling,Micro EDMilling, Micro Wire-cutting, and Micro on-line measuring have been accomplished and tested. In the developed machine a dual spindle design for Micro CNC milling, and for the manufacturing of icroelectrode and the following micro hole or die making by EDMilling, respectively is proposed and constructed. The
necessary software written in Borland C++ language is developed as well. The Micro CNC milling is tested by the use of a milling cutter of 0.1 mm diameter and by a special design diamond tool. Satisfactory results are achieved. The microelectrode is produced via WEDG process, and it is used for micro hole drilling and 3D micro parts manufacturing by micro EDMilling. In Micro wire-cutting a 20µm diameter fine wire is used. A novel mechanism that allows vertical/horizontal/slant angle wire cutting is designed. Micro parts such as outer gear, internal gear, rack, etc. having no taper angle on the machined part are successfully manufactured. A micro pagoda of size 1.25x1.25x1.7 mm is also produced to demonstrate the machine’s superior ability. Furthermore, based on the “short-circuit principle” and the micro probe manufactured by WEDG process, an on-line micro part measuring system to evaluate the flatness of the machined part, and the circularity and straightness of the micro-hole is developed and implemented.
