According to the research it was concluded the main conclusions :
1) Change fixed by axial force and temperature of the process feed under specified load begins after 0.4 seconds from the beginning of the process .
2) The dependence of the geometry otbortovok feed and thickness of the workpiece .
3) The modeled experimentally axial force and the temperature in the cutting zone .
4) The dependence of the strength of the threaded connection on the section of the feed .
5) proved hardening of the material in the hole formation zone .
6) The resulting hole corresponds to the admission of the inner diameter of 7 degree of accuracy .
7) The profitability of this study is 25%.
8) Recommendations on the use of the method in the production .
