IMPROVEMENT OF PRODUCE QUALITY

7
Non-parametric approach is shown to be appropriate for problems of optimization of machine part surface characteristics depending on the surface functional properties.
12
The problem of machine part surface underfeature optimization for a given functional characteristic is considered. The challenge related to insufficient information provided by standard parametric criteria for surface microrelief estimation is analyzed.
15
The necessity of creation of database of nonparametric criteria for estimation of functional surface microgeometry is justified. Stages of the database design and selection of instrumental means to be used are considered. Structure and logical scheme of the database are described.
19
Effect of regular microrelief of friction surfaces with solid film coating on adhesion of the coating to the surface, friction coefficient, and endurance of friction couples at high temperature in vacuum is investigated. The coating on the base of molykote are analyzed. Vibratory burnishing of the surfaces to produce regular microrelief is shown to increase adhesion of the coating to the surface several times and allows for control over the coating quality.
23
Causes of dimensional instability of instrument components and materials are considered, physical mechanisms of the instability manifestation are described. A combined computational and experimental method is proposed for evaluation of dimensional instability of assembly units. Urgency of the method application to precision instrument design is noted.

60
The problems are considered of manufacture produce models design on the base of a complex-geometry prototype and accuracy analysis of the models. Possibility is discussed of the use of 3D scanning data for the models development.
64
Basic principles are considered of students training at surface mounting laboratory. Examples are presented of approaches to education model with the use of installation equipment.
67
Dynamic demand during control system operation is shown to necessitate a change-over to adaptive scheduling. A method is proposed for description of adaptive scheduling process allowing for analysis of the process dynamics and evaluation of reasonability of switching to new production. Theoretical propositions are confirmed by presented results of applied computer realization.
