ПІДГОТОВКА МОДЕЛЮВАННЯ ФРЕЗЕРНОЇ ОБРОБКИ ДЕТАЛІ,ВСТАНОВЛЕНОЇ У ФРАКТАЛЬНИХ ЛЕЩАТАХ

Abstract

The article is a publication of scientific and methodical character. The article is devoted to the preparation of a virtual experiment of milling processing of a complex profile part, which is installed in a fractal vice. It was determined that fractal vices are presented on the technological equipment market in a very limited range. At the same time, the cost of fractal vices is unreasonably high. The cost is commensurate with the cost of the milling machine itself. However, modeling the processing of a part mounted in a fractal vise is of considerable academic interest. Fractal vices use Pascal's law on the plane (with some assumptions). The mathematical model proposed earlier was further developed. The model is flat and consists of a system of three differential equations of the second order. The equations describe plane-parallel and torsional movements of the part. Selected main parameters and their recommended values for the mathematical model of the processing process. At this stage, the main goal of the virtual experiment is to compare the set and real trajectories of the milling cutter. Also, the goal is to analyze the influence of parameters of elastic-damping elements, clamping force, etc. on the result. A matrix of options for conducting a virtual experiment is proposed. The matrix provides a large number of possible movements of the cutter relative to the part (simple, complex, locked, unlocked). It was determined that the matrix of options allowsfor a large number of possible processing options. From this set, several options are selected, the most suitable for further modeling and comparison with the results of a natural experiment. It is believed that the technological system "machine –vice –tool –workpiece" is a closed dynamic system with negative feedback. However, it is necessary to investigate the behavior of the system without feed-back and compare it with the rest of the experiments
