摘要　　　本實驗係採用較先進之CNC放電加工機,以煤油為主要之加工介
電液,並經由各種不同的加工條件,（極性,電極種類,脈衝時間,放電電流,
行星式搖動,鋁粉添加及工件材質狀態等)設定與加入來進行微能量之放電
加工,並由所獲的之工件加工效率(材料去除率及相對電極消耗率比）與表
面完整性（粗度,微裂,EDAX,EPMA及微硬度等）結果@分析而得最佳放電加
工條件

ABSTRACTan advanced adaptive control cnc edmmachine is adopted
in this research,and keroseneis used as a primary working fluid(
dielectric). a minute energy edm machining is operatedin this
experiment through various settings ofworking conditions(such as
change of electrodepalarity,electrode material,discharge
duration,discharge current,planetary motion of electrode,
aluminum powderaddition in dielectric and Elgiloy workpiece
material status etc)and an optimal edm working condition is
obtainedthrough analyzing the results of working efficiency(such
as material removal rate and relativeelectrode wear ratio)and
surface integrity(such as surface roughness,microcrack,EDAX,EPMA
and sectionalmicrohardness etc)
