Non-traditional machining are showing the prominent application in electronics engineering, micro machining , aerospace applications and now a days in biomedical engineering Photochemical machining (PCM) is used as one of the best micromachining technique for machining of difficult-to-cut material with appropriate machining parameters combination. The ferric chloride is used as etchant for machining of stainless steel-304.In the present work, an effort is made to explore the potentialities of application Regression Analysis (RA) in photochemical machining process. Design of Experiments (DoE) with Full factorial (L27) is worked out with machining parameters such as time of etching, temperature of etchant and concentration of etchant on the predominant micromachining criteria like Material Removal Rate (MRR), Surface roughness (Ra), Undercut (Uc) and Etch Factor (EF). Based on the observations, regression models are derived with acceptable degree of correlation between experimental and regression values. The values of coefficient of regression are showing a good agreement in experimental values and predicted by the regression model with minimum percentage error.
