抄録

<p>In general, removal machining cannot fabricate a hole on the inside wall of another hole. This means that removal machining has the limit on the degree of freedom of its fabricatable hole shape. To overcome the limit, our laboratory aims at the establishment of the method to fabricate such holes. Its previous studies developed the devices which can fabricate the holes by using with a die-sinking electrical discharge machine (EDM). However, those studies dealt with the improvements of the length, diameter, and straightness of the fabricated hole, and did not deal with the enhancement of the surface roughness of the fabricated hole. So, this study has developed the method to enhance the surface roughness by realizing the finish machining of the inside wall of the hole. The experiment result proves that the developed method has the abilities to finish the inside wall of the hole and to enhance the surface roughness of the hole.</p>
