NIOBIUM CARBIDE (cas 12011-99-3) (NbC) exhibits important properties which make it an alternative for cutting tool material. Nowadays, the cutting tool market is dominated by the tungsten carbide, which is used in cemented carbide grades of tool materials. However, the research of a novel substrate material for cutting tool application requires mainly two aspects of study. The assessment of the cutting tool characteristics which influence the machining performance, and the machining experiments themselves. Thus, the features evaluating of the cutting tool made of niobium carbide, which indicate its potential application as the main hard phase in cutting tool substrates, were performed. Cutting tools analyses were carried out in parallel with machining experiments. Tool life experiments were carried out in external cylindrical turning conditions, in order to evaluate tool lifetimes and tool wear evolution of the cutting tools in study.
