Wire electric discharge machining (WEDM) has become a key unconventional technology, as it offers a perfect solution for manufacturing machine-made components such as oil hardened nickel (non-shrinking) steel (OHNS) stainless steel and full forms which are not feasible with traditional machining techniques. Few scholars have tried to model this method due to an outdated number of operation variables and answers. In this paper, we will take the readings from the following parameters in WEDM including dielectric conductivity pulse width, time between pulses, maximum feed rate, servo control mean reference voltage, short pulse time, wire feed rate, wire mechanical tension, injection pressure on a distinct procedure responses including MRR and SR. In this various optimization and relation finding methods are shown. The cutting of OHNS steel using a wire electro-discharge machining method with copper electrodes was studied in this article. During this project L36 orthogonal array supporting the in the tests, Taguchi laboratory architecture was used. The analysis of variance is accustomed to evaluate data to find the right answer parameter conditions. The most machining parameters are performance measurements for dielectric conductivity (DC), pulse width (PW), time between pulses (TBW), maximum feed rate (MFR), servo control mean reference voltage (SCMRV), short pulse time (SPT), wire feed rate (WFR), wire mechanical tension (WMT), material removed rate (MRR), and surface roughness (SR) have been chosen to calculate the parameters. The use of response tables and graphs to determine the best parameter levels is common within the WEDM process.
