Abstract


This study presents a numerical modeling approach to optimize an ultrasonic concentrator for micro electrical discharge machining (microEDM) applications at a target frequency of 40805 Hz. The concentrator’s dimensions and shape are adjusted through an optimization process to achieve a high amplification coefficient. A nodal channel is incorporated to mark the region where the amplification is minimum. The resulting concentrator has a frequency of 40557 Hz and an amplification coefficient of 2.71. The concentrator and transducer are connected using an 18 mm long M12 bolt. Testing validates the model, which results in an eigenfrequency of 40696 Hz, which is subsequently machined to reach the target frequency. The study demonstrates a valuable method for designing and optimizing concentrators for specific frequency applications.
