抄録

It is very important to machine micro holes with large aspect ratio on workpiece in industry. An EDM drilling device by using piezoelectric elements has been newly developed. Wire electrode with the diameter of 0.1-0.5 mm used in the machining device is directly driven without any holder. The electrode is driven with several kinds of control modes, involving gap distance control, feed control of electrode, jumping motion and vibrational motion of the electrode. By feeding the wire electrode considering the occurrence of electrode wear, it doesn't need to exchange the electrode. The removal rate is so high compared with the rate by machine tools on the market under the same machining conditions. The scale of the device is very small with the length of about 100 mm. Several micro holes can be machined very rapidly by running multiple miniature devices simultaneously.
