Abstract

It is necessary to machine holes of complicated shapes for building pipelines of pneumatic or hydraulic equipment. However, the degrees of freedom of machinable hole shapes are limited, because holes are usually fabricated by drilling. To improve the degrees of freedom of these shapes, the authors have devised a method of fabricating a hole on the inside wall of another hole by means of electrical discharge machining. The method employs a very simple device. The results of the fundamental experiments indicate that this method has the ability to machine such a hole.
