| Research Abstract |
A machining process by using the lathe-type electro-chemical discharge machine was developed for the fabrication of small parts made from insulated materials. After the chemical reaction of glass to sodium ion in electrolyte is accelerated by discharge heat, sodium silicate was generated. The dissolution in the electrolyte causes the removal. When an electrode was fed at a constant speed, the machined surface was smooth. A prototype of an acceleration sensor was made in trial as an example.
