| Abstract: | The finishing of turbine blisks, a critical technology determining the final geometric accuracy of blisks, can be implemented efficiently with the electrical discharge machining (EDM) Upon the basis of the design of the electrode for blisk EDM finishing, the searching of an interference free path for feeding an electrode through twist channels of a rimed blisk is carried out, in which the kernel problem is the determination of the electrode kinematic constraints An implementation of the path searching algorithm is illustrated with an example at the end of the paper |
