Modeling and multi-objective optimization of low-frequency vibration-assisted chemical machining using central composite design in response surface methodology

Increasing the etching rate is one of main optimization targets in chemical machining (CM). Traditionally, this target fulfilled by some costly techniques like selecting stronger etchants and increasing etchant concentration. Also, other methods temperature stirring agitators are employed for rate. One advantages these reduction consumption acidic which results cost making an eco-friendley process. In article, a systematic experimental study performed on vibration-assisted CM copper. technique, workpiece vibrates during CM. For evaluating performance machining, effects amplitude frequency vibrations, along with concentration etchant, material removal rate, surface roughness undercut studied experimentally. The experiments designed Central Composite Design (CCD) Response Surface Methodology (RSM). multi-objective defining desirability function. optimal vibro-assisted process parameters 60 ̊C, 600 g/l, vibration 25 Hz, 1.5 mm, to get outputs desired parameters.
