RT Journal Article SR Electronic A1 Vasilko, Karol A1 Murčinková, Zuzana T1 Modification of the Classical Theory of Metalworking JF Manufacturing Technology Journal YR 2021 VO 21 IS 3 SP 405 OP 412 DO 10.21062/mft.2021.044 UL https://journalmt.com/artkey/mft-202103-0009.php AB The paper derives mathematical and ggraphical relationships between technological parameters and result of metalworking, in the application of progresive cutting materials based on coated cutting tools of sintered carbide and cutting ceramits. The development of new cutting and machined materials leads to new perspectives on their interaction in the machining process. This process leads to patterns between cutting conditions and machined results. These need to be defined and used in favor of efficient machining of mechanical components in practice.
