The main objective of this work is a comparision of different cooling techniques, namely cutting zone cooling, cutting tool cooling and workpiece cooling. The literature survey related to the analysis of surface texture (Ra) and tool wear (VB_c) after applying different cooling techniques was also taken into account. The analysis revealed that the applied cooling technique has a significant influence on the values of parameters of surface’s roughness. Furthermore, in all cases observed, there was a positive influence of cryogenic machining on selected physical and technical aspects after turning and milling such materials as Inconel 718, titanium alloy Ti-6Al-4V, aluminium alloys and elastomers. This work can also be considered as a starting point for further research and the analysis of machinability during cryogenic machining.

Celem niniejszego artykułu było porównanie metod obróbki kriogenicznej: chłodzenia strefy skrawania, chłodzenia przedmiotu obrabianego oraz chłodzenia narzędzia. Przedstawiono wpływ powyższych metod na chropowatość powierzchni obrobionej (Ra) oraz zużycie narzędzia (VB_c). Porównanie wykazało istotny wpływ metody obróbki na chropowatość powierzchni obrobionej. Ponadto we wszystkich przypadkach zauważono pozytywny wpływ obróbki kriogenicznej na wybrane właściwości fizyczne po toczeniu i frezowaniu takich materiałów, jak: Inconel 718, stop tytanu Ti-6A1-4V, stopy aluminium, oraz materiały elastomerowe. Może to stanowić punkt wyjścia do dalszych badań skrawalności materiałów w niskiej temperaturze.
