摘要

在追求輕薄短小的世代中，精密製造技術是高科技生產製造的發展基礎，且由於微機電系統(Micro Electro Mechanical System)的蓬勃發展，各種精密製造技術備受重視。微細加工是精密製造技術的主流，目前在微細加工中常以單發放電加工機（Single Pules EDM）製作探球、探針、微細孔、微細槽、形狀加工等加工，單發放電加工是精密製造技術其中的一環，學術界在單發放電加工的各種相關特性研究如：工件去除率、電極的消耗、表面的改質、加工液添加物、脈衝電壓或電流及幅寬等探討，皆希望增進對放電加工的了解，以充分提供加工技術的改善，並能支援精密機械工業的發展。
本文鑒於學術界及業界對單發放電加工在加工液中所產生電弧形成氣泡與壓力的相關特性的研究較少被提出，本文將就這一方向做探討及研究，從各種間隙的介電強度、單發放電脈衝電壓、電流的大小及脈衝幅寬對放電電弧產生氣泡所形成壓力加以研究，期望能藉此對單發放電加工的應用提供更寬廣的分析與應用，對高科技生產製造的發展基礎達更高願景。

In the era of pursuing small and light, the technique of precision producing is the development of high-tech manufacturing base, with the regard of rapid and prosperous promotion of MEMS (Micro Electro Mechanical), and as the result, the technique of precision producing is highly important. Micro processing is the mainstream to the technique of precision producing, nowadays it is often used in the micro-machining with single pules EDM for micro-hole, probe, micro-groove, shape processing. Single pules discharge processing is one link of precision manufacturing, where could be seen in the academic studies and exploration related to characteristics of single pules discharge such as: workpiece removal rate, electrode consumption, surface modification, processing liquid additives, pulse voltage of discharge or current, and which all wish to improve their understanding of EDM and to adequately provided the improvement of processing technique, which would support the development of precision machinery industry.
This study, in view of fewer study was made regarding the application on pressure in dielectric fluid by bubbles and arc from single pulse discharge in academia and in manufacturers, is to aim at those exploration such as dielectric strength in a variety of gaps, pulse voltage of single pulse discharge and current, pulse time, and the formation of air bubbles and pressure formed by arc from discharge, hoping to provide a broader analysis and application in single pules discharge application, and letting the development of high-tech manufacturing base move forward to the technique of precision producing technology in multiple integration, expecting to reach a higher vision.
