ON MULTI-FACTOR MODELING OF FREE-FORM SURFACE PROCESSING Serdyukova D.A., junior researcher, Master's Degree Student, e-mail: serdyukova.dasha2014@yandex.ru Ponomarev B.B., D.Sc. (Engineering), Professor, e-mail: pusw@istu.edu Irkutsk National Research Technical University, 83, Lermontov St., Irkutsk, 664074, Russian Federation Abstract The paper presents an argument for the need for research in the field of multifactor modeling of the process of the free-form parts surfaces’ processing with spherocylindrical cutters on five-axis CNC machines. The experience of using the finite element method and CAE systems in solving such problems is generalized, the scientific novelty is substantiated and the purpose of the study is determined, which is to establish the relationship between the parameters of the stress state of the tool with the processing conditions, temperature changes and the dynamics of the process. The main stages of the development of a software complex for modeling the removal of an allowance for finishing milling of complex surfaces and conducting research aimed at solving problems related to the development of a computer model of the process of forming a part and assigning optimal cutting conditions at the design stage of a technological process, taking into account the technical capabilities of equipment and tools, are presented. Keywords Shaping, milling, five-axis machines, cutting forces, cutting conditions, LS-DYNA.
