Короткий опис (реферат):
Сomplex technologies are technologies which consist of a certain set of stages and
technological processes. Using the theoretical basis of the systemic and synergetic approaches,
the technological process of manufacturing of such parts has been represented as a process of
qualitative and quantitative changes of the object. Taking into account the phenomena of
technological heredity, it has been assumed that physical and mechanical properties, in
particular, tensile strength, proportionality limit, relative narrowing and resilience, as well as
characteristics of the quality of the treated surfaces and processing accuracy can be
transformed during the complex technological process. To describe the transformation
processes of quality indicators, a set of experimental studies of the roughness of the treated
surface during machining of parts with high physical and mechanical properties has been
carried out and mathematical models have been obtained. To determine the conditions of the
integrated technology, it has been proposed to use a complex of dimensionless characteristics -
relative changes of the coefficients of the mathematical model. The obtained mathematical
models of the processes of mechanical treating of steel 38HN3MFA make it possible to
determine the processing conditions that ensure the formation of a given set of quality
indicators.
