The paper covers a single cutter lathe thread turn milling simulation that significantly reduces physical testing costs. The turn milling process involves a synchronized tool (helical mill), and workpiece rotation with a radial oncoming feed through a mill and workpiece relative movement. The cutting rate occurs by the mill teeth movement over the workpiece. The machining depth in each pass varies from zero to the max value, a common milling process feature. The proposed approach simulates the process parameters through thread turning or incomplete circular groove turning of workpieces attached offcenter to a lathe tooling. The proposed turn milling simulation method has reduced the number of machined referenced parts by 710 times. Accordingly, the experimental research period and cost have also been reduced. The research has revealed that the VK6M hard alloy tool life in turn milling with coolant is 50 times longer than the R6M5 HSS tool life while the useful tool life (measured as the number of parts machined within the tool life) for VK6M tools in turn milling with coolant is 50 times higher than that of R6M5 HSS tools.

The results of the research project are published with the financial support uf Tula State University within the framework of the scientific project No. 2017-42ПУБЛ.
