Streszczenie / Summary:

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 (VBc) 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.
