| Abstract: | This work investigates the influence of the pulse repetition frequency on the profile generated within pulse electrochemical dimensional machining of nickel foil using a cylindrical electrode tool. Geometrical criteria for the shaping accuracy characteristics are introduced. It has been demonstrated that, irrespectively of the criterion calculation method, the significant influence of the pulse repetition frequency on the shaping is observed. Herewith, the frequency variation makes it possible to determine the extreme criterion point corresponding to the best replication of the electrode tool. It is established that the variation of the pulse repetition frequency influences first of all the region of generation of the outer corner of the formed profile. |
