Прогнозування надійності інструментів збірної конструкції

Abstract

The mathematical model for determining the reliability of modular tools with the method of backup. We consider three types of provision: loaded, unloaded and lightweight. The dependences obtained for calculating the reliability of cutting tools used to predict their performance. The mathematical model of reliability of a modular trailer mill is developed as systems. Strategy of replacement of cutting elements of a mill for achievement of expedient level of its reliability which is defined by criterion of the resulted expenses is defined.
