MODELING AND SIMULATION OF DEFORMATIONS IN THE FEED SYSTEM FOR ULTRASONICALLY AIDED MICRO-EDM
Keywords:
EDM, µEDM, µEDM US, feed system, deformation simulationAbstract
The paper deals with the study of deformations within the roller screw from the feed system, used in ultrasonically aided micro electrical discharge machining (µEDM+US). The study is focused on the deformation of the roller screw’s threads in contact with the three rollers, components of the nut, in two constructive variants. The contact surfaces are determined and isolated on the roller screw, which is then introduced in a numerical simulation module, to calculate its deformation in different positions of the nut. The results pointed out that the load deformations of the roller screw are less than 0.1 µm, so µEDM+US precision would not be affected significantly.
