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).

Development of industry is marked by the development and application of new materials with characteristics that broaden their applicable uses. Information about material machinability is very important for the machining technology. Precise and reliable information on the machinability of a material before it enters the machining process is a necessity, and this brings the verification of technological methods in practice. This article presents the conclusions of machinability tests on austenitic stainless steel Crl7Nil4Mo3Ti, and describes important concurrent parameters for the cutting zone during the process of drilling. This article presents the conclusions of KEGA grant agency at the Ministry of Education in Slovakia, for supporting research work and co-financing the projects: Grant work #3/7166/2009.
