Abstract
When soft materials such as gelatin gel are fabricated by cut processing, machining marks are generated by contact with the cutter, and microfabrication is difficult. On the other hand, by utilizing micro-Electrical Discharge Machining (micro-EDM), gelatin gel can be machined without contact, so it is possible to perform microfabrication on a gelatin gel. When processing grooves on gelatin gel using micro-EDM, resolution of grooves can be increased by the electrode approaching the gelatin gel and processing with a low applied voltage. Furthermore, shortening the time for applying heat during processing may also increase the resolution of the groove. Therefore, in this research, we investigated the change of the processing characteristics when changing the speed of wire in micro-EDM on gelatin gel.
