Subject aims expressed by acquired skills and competences
This subject includes an analysis study of cutting properties of tools and of the machinability of materials. In another part of the subject applications of acquired information and regularities for all methods of machining in extreme conditions during the special production of shapes and formed surface areas are used. This part includes as well a technological view for machining by applying microelectronics and computer techniques. This subject is dealing with machinability and cutting power of cutting tools, types of machining and robotics and unmanned centers.
