First is connected with the possibility of decreasing forces in cutting processes by electrochemical intensification support. Second example presents application of electrochemical dissolution for increasing metal removal rate or surface quality in sequential machining process (with combination of electrodischarge micromachining). 1 Introduction In group of methods worked out for machining of technological equipment, MEMS parts, functional prototypes and tools for micro-casting and micro-forming special attention is paid for application of microcutting and unconventional processes such as the laser beam, electrodischarge and electrochemical machining. The recent development is focused on 3D-shaped surfaces manufacturing. In case of microcutting the main problem during machining is connected with size effect [7, 13]. Significant forces in machining area limits its application to machine 3D parts made of soft materials and dimensions > 100 μm. Because of this fact the special attention is paid for unconventional processes such as: electrochemical (ECMM) and electrodischarge (EDMM) micromachining,
