METHODOLOGY OF ESTIMATION OF THE FUNCTIONAL RELIABILITY OF TECHNICAL SYSTEMS

Abstract

In this article a decomposition of the round broaches teeth sharpening operation is constructed. Analysed operation is divided into «tool», «workpiece», «machine», «device», «cutting-cooling technological means» due to junctional characteristics. As contrast to the known schemes of decomposition, subsystem «contact zone» and «tool amendment» are distinguished. It was established that during the teeth broaches grinding the technological parameters of the system can be changed over a period of time due to various factors. In the proposed scheme, the structural features of abrasion are reflected in backward and forward linkages.
