Research on Electrode Design and Computer Simulation of Manufacturing Shrouded Turbine Blisk by EDM

Abstract:

A shrouded turbine blisk is taken as the research object. Based on NURBS surface modeling theory and by using SolidWorks software, a 3D model of the blisk was gotten. An electrode was designed according to the characteristic of channel between two blades of the blisk. A set of fixtures for manufacturing the blisk was designed, which can realize measurement on-line. Computer simulation of manufacturing the blisk was conducted. The simulation results show that there is no interference between the blisk and the electrode. So the feasibility of manufacture is verified. The simulation results have provided an effective basis for the subsequent processing of the blisk.
