| Outline of Final Research Achievements |
On the lathe-type electrochemical discharge machine for machining insulated materials by discharge in electrolyte, a machining method of a non-circular section in a cylindrical glass rod was developed. A tool electrode suspended with a set of parallel thin leaf springs was pressed on the glass rod at a thrust of 10-mN order by controlling with a voice coil motor while the electrode was moved. By an on-off control of the applied voltage to the tool electrode, a non-circular section was machined. Machining a square section was demonstrated and the machining accuracy was evaluated.
