| Summary: | 碩士 === 國立中央大學 === 機械工程學系 === 85 === 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)
