This paper introduces a new method for simulating the micro-EDM process in order to predict tool wear. The tool and workpiece are defined by NURBS surfaces whose shapes result from an iterative crater-by-crater deformation technique driven by physical parameters. The simulation method is validated through a comparison with experimental data. Different simulations are presented with an increase in computation accuracy in order to study its influence on the results and their deviation from expected values.

A comparative study between NURBS surfaces and voxels to simulate the wear phenomenon in micro-EDM Article dans une revue avec comité de lecture; ;PERNOT, Jean-Philippe (CAD Solutions LLC (imprimé) and Taylor & Francis Online (en ligne), 2016)
The prediction of the tool wear phenomenon in the micro electro discharge machining technology would be of a great use in the optimization of tool shapes. In order to do so, the ability to rapidly and precisely simulate ...
