Havrylov T. Modeling and automation of design of rational schemes of cutting of sheet materials on shoe parts

The dissertation on competition of a scientific degree of the candidate of technical sciences on a specialty 01.05.03 - mathematical and software of computers and systems - Open International University of Human Development "Ukraine", Kiev, 2021. The main purpose of writing this dissertation research is to simplify the work of the cutter when performing the technological process of cutting sheet materials, taking into account the properties and qualities of these materials. To accomplish this task, the following steps were taken: • The own method of approximation of a contour of a detail of a difficult configuration for the purpose of the further construction around them of hodographs is developed. • A hodograph vector of the function of dense distribution of details of each type is designed around the approximated contour. • On the basis of the built hodographs of details of these types the lattice laying is developed. • And already on the basis of the chosen dense laying the abstract scheme of cutting is designed. According to the developed methods, a software package was created using computer technology to solve the problem of developing cutting schemes. The developed software of automated design of rational schemes of cutting will allow to minimize working time of performance of operations of technological process of cutting. The developed programs are based on their own ideas, some possibly taken from the literature, but refined and modified by the author. These ideas are set out in articles and approbations at conferences.
