dc.description.abstract-translatedThe subject of this experiment was to produce parts with a specific shape and submillimetre elements. The parts represented components of commercial sparkplugs and the machined section was made of almost pure nickel. Relatively narrow required tolerance of parts (hundreds of micrometres), in combination with a large addition of material to the semi-finished product (several millimetres) and the required number of parts manufactured by one cutting insert for a very small time cycle led to the implementation of several tests to find ideal cutting inserts and conditions for production. All of the machining was done under dry conditions and the lowest possible machining time was also taken into account. Seven inserts with potentially suitable cutting-edge geometries were selected for testing. They were positive ISO C and ISO D inserts. After initial testing and determining the most suitable conditions for the most inserts, cutting forces during machining under constant conditions were measured. After the machining, each part was closely inspected by the microscope and all the critical dimensions, general shape and state of the surface were evaluated. In the course of the experiment, a significant effect of the geometry of the cutting insert was demonstrated. The best performing of used cutting inserts for these conditions was ISO D shape with a nose radius of 0.2 mm and a highly positive rake angle. In terms of the thin layer used, a TiAlN PVD coated insert seems to be the most ideal as it should significantly increase tool life. To verify this assumption extensive long-term testing would have to be done. These results confirm the importance of selecting appropriately positive geometry for turning small features in soft alloys along with the influence of nose radius with regard to depth of cuten
