“…Що дозволило адекватно оцінити вплив кожного технологічного фактору на процес лазерної обробки медичних ендопротезів. Опираючись на результати проведених раніше експериментів з відсіювання, було встановлено, що на продуктивність та якість лазерного різання стентів чинять суттєвий вплив такі технологічні фактори [10][11][12]:…”

When designing technological processes, developers always face tasks aimed at increasing the efficiency of the laser cutting process of tubular blanks, as well as improving technological equipment. The main efforts are aimed at improving the quality indicators, in particular the roughness of the cut surface, as well as the elastic characteristics of medical endoprostheses.The analysis of scientists' research on laser processing of medical endoprostheses made it possible to determine the main priority directions of scientific research, namely the search for ways to improve experimental equipment and optimal control parameters of the technological process of laser processing of tubular thin-walled blanks.The purpose of this is to increase the elastic characteristics of the medical endoprosthesis, in particular its flexibility due to the reduction of the width of the cut, as well as the optimization of the technologicalprocess of laser cutting of the tubular thin-walled blank.On the basis of a priori information, methods and approaches were developed to improve technological equipment in order to increase the productivity and quality of manufacturing medical endoprostheses. Namely, a complex approach was developed to increase the elastic characteristics of the stent by reducing the width of the laser cut. In particular, the methods of mathematical statistics were used for the effective analysis of technological factors affecting the process of laser treatment of medical endopros-theses. Namely, mathematical models of the process of laser cutting of thin-walled tubular blanks were obtained.In this work, the optimal configuration of the experimental prototype of experimental equipment for the manufacture of medical endoprostheses (stents) was developed. Also, a technique was developed and optimization of the control parameters of the process of laser cutting of tubular blanks was carried out. The results of experimental studies showed the possibility of reducing the width of the laser cut, which made it possible to improve the elastic characteristics of the medical endoprosthesis.
