| Outline of Final Research Achievements |
In order to decrease the material removal per single pulse discharge, high electric resistance materials such as single-crystal silicon are used for electrodes. Experimental results show that with the silicon tool electrode, the peak value of the discharge current decreases, whereas the pulse duration increases. In addition, with increasing silicon electrode resistivity, the diameter of discharge craters decreases. As a result, the minimum diameter of rods machined using a silicon block tool electrode was 0.7 micrometers, which is smaller than the diameter obtained when using a copper tool electrode.
