Tokarchuk Oleksіі – PhD, Associate Professor of the Department of «Technologіcal Processes and Equіpment for Processіng and Food Productіons» of the Vіnnytsіa Natіonal Agrarіan Unіversіty (St. Solnyshchnaya, 3, Vіnnytsіa, Ukraіne, 21008, e-maіl: tokarchyk@vsau.vіn.ua.

Kupchuk Igor – candidate of technical sciences (Ph.D in Engeneering), Senior Lecturer  of the Department of General Technical Disciplines and Occupational Safety of Vinnitsa National Agrarian University (Sonyachna St., 3, Vinnitsa, Ukraine, 21008, e-mail: kupchuk.igor@i.ua).


The analysis of modern existing methods for producing internal thread  showed that one of the most promising methods, with significant technological capabilities and high productivity, is the method of plastic shaping (extrusion) of the thread with chipless taps.

The complex of known measures aimed at increasing the stability of taps and their reliability, consisting in the creation of new tool materials, improvement of the design and optimization of the geometry of the cutting part of the taps, improvement of the quality of working surfaces, the use of new types of cooling and optimal settings, do not solve the final issue of high performance and high quality manufacturing of thread holes in stainless and heat-resistant steels not only on highly automated equipment, but even on conventional ones.

It is substantiated that the most widespread are taps with a conical full-profile intake part; distortion of the pitch ΔР  at he tops of the turns in the transition zone is one of the main design disadvantages of chipless taps. A diagram of the formation of a thread  profile by chipless taps with a conical deformation pattern is presented. It is proved that the geometric incompatibility between the thread profile of the tap and the thread formed by it is one of the main reasons for the chipping of the tops located in the transition zone and a sharp increase in the torque of the   thread  extrusion The parameters of chipless taps are optimized and the advantages of their use in the process of thread extrusion are determined.

The main objectives of the research: to investigate the power features of the process of manufacturing threaded holes with chipless taps in stainless steel parts in order to develop optimal designs of taps for through and blind holes; to develop a technological process for the manufacture of chipless taps of the necessary technological equipment for a grinding machine, as well as for grinding the threaded profile of taps.

Keywords: tap, thread extrusion, stainless steel, threaded hole, thread

History of journal:

In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published  94 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Kaletnik H.M  PhD , professor, academician NAAS is the chief editor of the "Vibrations in engineering  and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
