Abstract: The article presents the results of experimental studies on the influence of various cutting regimes on the surface roughness of high-hardness hardened steel obtained after face milling with polycrystalline cubic boron nitride (PCBN) tools, both uncoated and with wear-resistant coatings. The aim of the research was to compare the surface roughness indices of hardened steel obtained by face milling using tools with PCBN without coatings and with TiSiN and TiAlN coatings. Various cutting parameters such as feed rate, cutting depth, and cutting scheme were considered to determine their impact on the machined surface roughness. The machining was performed on a vertical milling center DMU 80 eVo Deckel Maho using a SECO TOOLS face mill with replaceable cutting elements (N = 5). The results showed that tools with TiSiN and TiAlN coatings provided a lower surface roughness in face milling compared to uncoated tools. The influence of cutting schemes (up-milling, down-milling, symmetric milling), feed rates, and cutting depths on the surface roughness of hardened steel were analyzed. The article substantiates and provides recommendations for optimizing cutting parameters to achieve better surface roughness results when face milling hardened steel with PCBN tools with and without wear-resistant coatings in production conditions, enhancing process productivity and economic efficiency.
