Influence of macro and microgeometry machined surface on ultrasonic aided electrodischarge machining
Source abstract
Abstract
The paper deals with theoretical and experimental researches concerning specific mechanism of material removal process through electrodischarge machining (EDM) aided by ultrasonic (US) longitudinal-i.e. normal on machined surface–vibrations of electrode (EDM+US). The influence of machined surface shape at macro and microgeometric level on material removal process is highlighted through finite elements analysis (FEA) in agreement with experimental data obtained at finishing different kinds of surface types. The completion of optimisation conditions referring to input working parameters, specific to pulse types, achieves the improvement of all main output technological parameters comparatively with classic EDM.
