The study presents the results of machinability tests on a new X8Cr20Ni10TiMo austenitic stainless steel which is applied to food processing industry, and it also describes important parameters of the cutting zone during the process of turning. The paper discusses the analysis of selected domains through basic indicators of steel machinability. In the cutting tests, cutting speeds ranged from 80 to 150 m/min, the feed rate - from 0.1 to 0.6 mm. The CNMG 080408-MF solid carbide indexable insert was used. The value of the tool wear criterion, VBK, was 0.3 mm. Chips were analysed with Scanning Electron Microscopy (SEM).
