This paper discusses the application of electrochemical machining to the production of gas turbine airfoils. A new adaptively controlled system for maintaining a constant gap between tool and work is described. This system coupled with a unique tooling concept allows the production of airfoils in difficult-to-machine materials to heretofore unobtainable tolerances.
