Directional formation of operational properties details in technological environments
Abstract
The main task of machine production is assuring their operating quality, directly depending
on components operating characteristics. Characteristics, assuring the components performing
set functions under set operating conditions and assuring set components’ life, are considered
as operating characteristics of separate surfacesand whole components. The common method of
engineering support of the operating characteristics is based on necessity of assuring certain engineering and manufacturing quality parametersduring production based on the assumption that
they warrant reaching set operating characteristics. Itis already proved that different sets and sequences of process methods can lead to similar components quality engineering and manufacturing
parameters, but to significantly different operating characteristics. The method of process design,
based on superimposing process impact results on production subject, has run its course.
Suggested concept of controlled forming of goods (in particular, components) characteristics
considers their reached quality as a result of transforming its separate parameters, taking into account operative impact on production object, as well, as succession and mutual influence of forming features. In order to describe the transformation a mathematical tool, allowing deterministic stochastic modeling of such transformation, was worked out. The present work includes using the concept for controlled forming of set operating characteristics of goods, using components as example. The perspective is to form technological solutions, 100% assuring directly set operating characteristics of operating surfaces or the whole component. It is demonstrated that the necessary and sufficient level of warranted assuring set operating characteristics should be limited and should take into account influence of the emergence of the technological process as a system on results of the elementary solutions, performed in such system.
