Abstract in different language:	This paper is based on the knowledge gained in the field of development and construction of tools for machining very hard and difficult to machine materials based on thermal spraying (for example NiCrBSi, Fe13Cr, Stellite 6 and others) and printed materials such as Inconel 718. Due to the methods of coating production, using heat technologies and their specific composition due to increased hardness and wear resistance, their conventional machining is very difficult. A common way of machining the coatings thus formed is by grinding. However, grinding productivity is low and production costs are relatively high. Therefore, it is necessary to explore the possibilities of machinability of thermal sprays and increase the cutting ability of tools, especially through more productive approaches and technologies. When machining thermal sprays, a large heat is also generated in the cutting area, which further helps to wear the tool edge faster. In the conventional method of machining by turning and milling, cutting materials such as cubic boron nitride (CBN) or polycrystalline diamond (PKD) are often used, precisely because of their high hardness or heat resistance
