A Holistic Approach for Zero-Defect Micro-EDM Milling
Micro-EDM (μEDM) milling is a well-established micro-manufacturing technique,which offers three-dimensional and flexible machining capabilities for structuring electrically conductive difficult-to-machine materials.There has been considerable progress in micro-manufacturing capabilities by μEDM in recent years.Nevertheless there still exist a few challenges in terms of process accuracy and efficiency,and the achievable shape accuracy in micro-EDM milling is limited to 3-4 microns in vertical direction and 2-3 microns in plane.In order to reach zero-defect manufacturing with this micro-sparking technique,a holistic approach for precision micro-EDM milling is pursued at Leuven University.To improve the overall performance of the micro-EDM milling process,various upgrading has been carried out on a SARIX? machine,which includes monitoring and controlling of the stability of the sparking process (gap variation and energy distribution etc.),wear compensation of the tool-electrode,and on-machine metrology.Preliminary experiments have been carried out with promising results,and further system integration and application on industrial demonstrators are in progress.
