• For the better quality in EDM process, it is recommended t
use DF3 as workpiece compare to the 304 Stainless steel.
• Dierent material and electrode can be used or electrode
workpiece or another e!periment. "t mi#ht ha$e dierent

•
&here is the dierent readin# o surace inish, 'a or Edmmachinin# process between DF 3 and 304 Stainless Steel
when this two types o materials are used as a workpiece
material .
• Surace inish is better when usin# DF3 as a material comp
to the 304 Stainless Steel. "t mi#ht happen due to the DF 3
characteristic that is a #ood machinability.CONCLUSION

METHODOLOGY
&he main ob2ecti$es o this pro2ects are
• &o in$esti#ate the most si#niicant parameter or EDM process.
• &o study the surace rou#hness or dierent materials with
dierent parameters.OB,ECTI-E OF THE STUDY
• Most o students are less care about the eect o durin# EDM
process.
• Most o EDM use will ace the tool wear problem.
• &he dierent types o materials used as workpiece also cause
the dierent time to inish o the EDM process.
• esides that, the surace inish is also based on the spark #ap,
current and ulse duration that is used durin the rocess.
PROBLEM STATEMENTS
• &his pro2ect concentrates on the e!periment o the surace inish
o Submer#e EDM.
• &he e!periment is made by usin# cooper as an electrode and
there are two dierent types o materials which are DF3 and 304
Stainless Steel as the current workpiece or the e!periment.
• &here are three parameter that ha$e been set up rom me which
is current, spark #ap and pulse duration.• Each o the e!periment will be measured three times with
surace rou hness tester to et the a$era e o the result.
