Parametric optimization of process parameters for EDM of stainless steel 304

Patel, N K (2014) Parametric optimization of process parameters for EDM of stainless steel 304. MTech thesis.



In EDM various techniques are applied to improve the material removal rate (MRR), surface roughness (SR) and tool wear rate (TWR) with different electrode combination. However, the machining parameters are also effective while machining. In this study, an experiment is performed to analyze the effect of machining parameters viz. discharge current (Ip), pulse on time (Ton), voltage (v) over the responses of MRR and SR. For this Tungsten carbide tool or electrode used while the work piece chosen as AISI 304 stainless steel which is utilized for manufacturing of various products in our daily life. For the conduction of experiments L9 orthogonal array was used to complete the runs. We found that discharge current is most significant factor after that pulse on time over response of MRR and in case of SR the voltage is effective parameter. For analysis and explanations STATISTICA 9.0 software is used.
