Parameter Optimization for Drilling Micro Holes in Tigr 5 by Electrochemical Micro Machining

Abstract:

Electrochemical Micro-Machining fields the solution for the challenges posed by future micro and nano machining technique as it offers innumerable advantages. The electrochemical micro machining can effectively be used for high precision machining operations. Intended for micro fabrication of TiGr5 based components like Nozzle Plate for Ink Jet Printer head and delicate 3D -electronic circuit board components, and components of avionics, the electrochemical micromachining is primarily employed. In this research study, an attempt is being made to evaluate and access the influence of machining parameters namely the voltage, current, electrolyte concentration and pulse on off ratio on the Radial overcut, and Machining Time during drilling of micro holes in 0.5mm thick TiGr 5. Preliminary investigations are carried out to create an optimized parameter window that defines the operating range of the governing parameters. Further, a central composite factorial experimental design technique is being applied to determine the optimal combination of the machining parameters level. Response surface methodology is used to determine the influence of the varying input parameters on the output product features.
