The paper presents typical modelling methods of thermal effects in the cutting zone when machining AISI 1045 carbon steel with differently coated carbide tools. The thermophysical properties of the workpiece and tested cutting tool materials were experimentally determined. For multilayer coatings deposited on the carbide tools, the composite layer with equivalent thermophysical properties was applied. Three concepts of modelling of the thermal effects were discriminated, i.e. an analytical algorithm, and FEM and FDM numerical simulations. Selected testing methods were considered in terms of their suitability to evaluate the optimal structures of thermal protective tool coatings and their practical applications.

W artykule przedstawiono metody modelowania oddziaływania cieplnego w strefie skrawania stali niskostopowej AISI 1045 narzędziami węglikowymi z naniesionymi różnymi powłokami ochronnymi. Eksperymentalnie wyznaczono właściwości cieplne badanych materiałów obrabianych i narzędziowych. Zaproponowano, do oznaczenia właściwości wielowarstwowych powłok narzędziowych, wykorzystanie idei powłoki kompozytowej o zastępczych właściwościach cieplnych. Przyjęto trzy koncepcje modelowania oddziaływań cieplnych, których podstawą są wyniki obliczeń z użyciem algorytmu analitycznego, oraz symulacji MES i MRS. Wyniki wybranych metod badawczych poddano analizie dla ustalenia ich przydatności w określeniu optymalnej budowy cieplnych powłok ochronnych i ich zastosowania praktycznego.
