• 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

•

&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.
