PT Journal AU Vasilko, K Murcinkova, Z TI Modification of the Classical Theory of Metalworking SO Manufacturing Technology Journal PY 2021 BP 405 EP 412 VL 21 IS 3 DI 10.21062/mft.2021.044 DE machining; chip formation; tool durability; cutting forces; material machinability 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. ER
