BACKGROUND: Review of analytical studies allowed us to conclude that existing technologies do not ensure cutting of highquality internal threads in shipbuilding products made from difficult-to-machine materials. AIM: A state-of-the-art 3D technology based on the design of an advanced thread-cutting tool is required to ensure high quality of the cut thread. Thus, it is necessary to develop a special cutting pattern to eliminate friction of tap side faces of the countersink tap with the surface of the cut thread. This will provide access of the cutting fluid to the cutting area allowing to lower the temperature and wash away small particles of the processed material warping the surfaces from the contact part of the tool. METHODS: Empirical methods were used, including observation, comparison, measurement, and experiment. RESULTS: The developed state-of-the-art 3D technology allowed for automating the calculation of the basic parameters for a thread-cutting tool and manufacture it in real-life production conditions. CONCLUSIONS: The developed advanced 3D technology to create a state-of-the-art internal thread cutting process for shipbuilding products made of difficult-to-machine materials and testing it in real-life production conditions allowed to improve the quality and productivity of manufactured products and solve the main issue of import substitution.
