Abstract
This paper presents a technological breakthrough in the manufacturing of miniature revolving surfaces using wire electrical discharge machining (WEDM). The principle of manufacturing highlights specific aspects of the technology concerning the necessary equipment and the steps taken during production. The process of manufacturing is presented mathematically, concerning the surplus of material that is to be removed. The technological solution proposed was validated in practice and it features some experimental results that were obtained. This solution puts forward a new alternative to the manufacturing of small-sized revolving surfaces for hard and extra-hard material parts.
