Modelling of micro electro discharge machining in aerospace material

Abstract

Micro EDM is a non-conventional, non-contact machining process where the material is melted and removed from the work surface by the sparks produced between anode and cathode immersed inside the dielectric medium. In the present day scenario the micro products play a crucial role in the field of biomedical, nuclear, defense, transportation and space application so its necessary to produce such components with desired precision and accuracy on the same ground my thesis revolve around the same concept of advanced and precision manufacturing. EDM has been used for decades for machining pieces for the aeronautical industry, but surface integrity, and consequently the reliability of the machined parts have been questioned for long time due to the thermal nature of this machining process.
