Finite Element Modeling of an Ultrasonic Horn Integrating the Tool for Micro-Electrical Discharge Machining

Abstract:

The paper deals with a strategy to obtain a complex conical ultrasonic horn, which integrates the tool for micro-drilling through ̵̵̼̳̹̳̱̼̈́͂˰̴̸̷̵̹̳̱̓͂˰̸̷̱̳̹̹̽̾̾˰˸ڌ̝̔̕˻̥̣˹˰̵̴̲̱̓˰̿̾˰̖̹̾ite Element Method (FEM) modeling. This approach comprises more than 20 stages, starting with preliminary determination of a basic profile stepped horn through mathematical relations. The next stages are based on Comsol Multiphysics FEM modeling, changing gradually different horn constructive elements and integrating the tool and their clamping parts. The entry data for horn geometry determination were the dimensions and own frequency of transducer subassembly, joining ultrasonic horn. Finally, the CAD file of horn was transferred to CAM file and CNC machined. Horn real own frequency obtained was very close to the result provided by FEM modeling.
