Abstract

Photochemical machining (PCM) is the non-conventional machining processes which produce burr free & stress free flat complex metal components. In the present work optimization of process parameters for Photo chemical machining of SS316L by using response surface methodology. Mathematical models have been developed to study the effect of input parameters on Undercut from the results of the experiments. The different input parameters such as time, concentration and temperature were set during the photochemical machining. Design of Experiment was done by centre composite design method by having 20 experiments to see the effect on etching of SS316L. Minimum Undercut was observed at the etching temperature 63.99, etchant concentration 769.69 gm/lit and 46.96 min etching time. The optimum material undercut was found 0.0815 mm.
