149 Application of Finite Element Method in Cathode Tool Design and Manufacture of Electrochemical Magnetic Machining Mohsen Ghobadi M Ghobadi@me iut ac ir Mo Gh mail@yahoo com Date of Submission 2010 08 10 Department of Mechanical Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor Dr Alireza Fadaie Tehrani mcjaft@cc iut ac ir Abstract Electrochemical machining ECM is a modern machining process that removal of workpiece atoms in it relies on the principle of ion movement in the electrolysis cells Compared with traditional machining methods ECM takes many advantages such as hard and brittle material machining ability with complicated shape and fast material removal rate without any residual stress whereas it s a non mechanical process Because of it s advantages against traditional machining it used for manufacturing of many complicated and strategic pieces that makes from hard and brittle alloys such as Nickel Titanium or Molybdenum alloys that needs minimum structural defects The most important problem in ECM is to obtain required shape of workpiece by using designed tool In the present work firstly the fundamental of ECM processes is perfectly studied Then a technique is developed for simulation of ECM processes in the present of Electric Magnetic Thermal and Fluidic fields based on equations govern on them by Finite Element Method FEM This technique is capable of handling three dimensional free surface tool design It possesses high computing efficiency good accuracy and flexible boundary treatment without the need for iterative procedure At continue a simple model of ECM set has manufactured and the process operations has tasted on it This set is first ECM in its kind that all substructure s produced by own technology Result of experiments shows that how electrical magnetic thermal and fluidic fields effect on potential field distribution Therefore we can use ECM simulation to guide ions in proper direction to converge electrode surfaces without any experiment cost The implementation results are compared with simulation results to verify viability of proposed method At continue two examples of tool design for turbine blade are given to demonstrate this method In the end there is a summary of thesis and suggestions for further studies Keywords Electrochemical Machining ECM FEM tool design non iterative algorithm free surface forming
