ANALYSIS OF THE MATERIAL REMOVAL IN HYBRID ELECTROCHEMICAL-ULTRASONIC MACHINING OF A 12% Cr STAINLESS STEEL
Keywords:
electrochemical machining, simulation, roughness, modelingAbstract
The paper deals with the presentation of an analysis for material removal process in the hybrid electrochemical-ultrasonic machining of a 12% Cr stainless steel. The Comsol Multiphysics software was used for the numerical simulation of the material removal process of the 12% Cr stainless steel. It was necessary to parameterize the models in order to study the behavior of the steel with Cr carbide constituents. A scanning electron microscope from POLITEHNICA University of Bucharest, named SEM QUANTA INSPECT F50, was employed to highlight the morphological structure of the machined surfaces. The influence of the material removal process on surface roughness was studied by varying the parameters of consumed ultrasonic power and current intensity.References
