Machining involves removing a surface layer from an object with the use of mechanical energy. It often happens that this process is very difficult or even impossible due to technical and economic problems ( big strength and tear resistance of the machined material). Therefore, new technological processes of removing the material from the machined object, have been developed. They involve, e.g. dissolution, melting or the material vaporization. These processes need energy of electric discharge, chemical reaction energy, and energy carried by a stream of particles the material destruction which occurs, then, are called the material dissolution (erosion). There are different classifications of dissolution machining The most popular one is electro discharge machining (EDM), electrochemical machining (ECM), stream-dissolution machining (i.e. electron-machining (EBM) and ion- machining (IBM). The purpose of this work is to present the problems connected with the computer aided electrochemical (ECM) as one of a few kinds of dissolution machining.
