АНАЛИТИЧЕСКОЕ РЕШЕНИЕ ЗАДАЧИ ОПРЕДЕЛЕНИЯ УПРУГИХ ДЕФОРМАЦИЙ ИНСТРУМЕНТА ПРИ КОНТУРНОМ ФРЕЗЕРОВАНИИ КОНЦЕВЫМИ ФРЕЗАМИ

Abstract

Analytical solution of problem for tools elastic strain definition is presented. The case of uniformly distributed radial component of cutting force is examined. The bending moment diagrams were plotted. The deflection curve of an end-milling cutter and its graphic interpretation are presented. Analytical relationship between milling cutter deflection and geometry features, physical-mechanical properties of material of cutter and applied cutting force is presented. The moments of inertia for any sections of standard milling cutters relative to centroidal principal and turned axis were calculated. It were plotted moment of inertia – cutter diameter and cross section area – cutter diameter diagrams.
