METHODS OF CONTROL AND DIAGNOSTICS

Poplavski J. M. � Investigation of the complex structure from CFRP/GRP composites through the use of the active thermography method

The active thermography method was used to study a complex, specially made composite sample with layers of CFRP and GRP. It is shown that the use of highly sensitive thermographic equipment through the use of modern software for image processing allows to quickly (in less than 5 minutes) obtaining a defect distribution in a multilayer structure (more than 20 layers) and control sandwich structure exfoliation. The possibility of using the method in field, shop and laboratory conditions is shown.

AUTOMATION OF THE TECHNOLOGY PROCESS TECHNOLOGY AND PRODUCTION, CAD

Kalyakulin S. Yu., Kuzmin V. V. � Automation of measuring equipment choice on the basis of design and technological parameterization in CAD

The article is devoted to the calculation automation of the technological processes parameters on the basis of the design technological parametrization. The essence of this parametrization consists in adjusting of the part parameterized drawing to the pre-designed calculation modules in the CAD system witch output information about the calculated parameters to the technological documentation cards. Since the drawing of the parameterized part is developed in the parametric mode, changing its parameters in the CAD system leads to a change in the "input" information in the calculation modules of the CAD system. The modules recalculate the parameters in accordance with the received values and automatically make changes to the technological documentation card, which is clearly demonstrated in this article on the example of a standard measuring equipment choice.
Key words: technological process, design and technological solution, technical documentation card, CAD module, material equipment

The results are analytical distributions of random numbers as mixture of exponential and Rayleigh distributions. The method of analytical approximation of this distribution is described. It can be used to model node molding in welding training systems for flow of commands to control imitator of variable velocity of molding.
Key words: manual arc welding, shortcuts, welding training system, time between shortcuts, variable velocity of molding, distribution

STANDARDIZATION, QUALITY PRODUCTION MANAGEMENT

Zhetesova G. S., Zharkevich �. �., Zhunusova A. Sh. � The quality level valuation of engineering products by the methods of index qualimetriya

Quality indices are used to assess the quality level of heterogeneous products. They make up an index of quality control. The article describes the methods for determining quality indices and defect indexes of professor A. V. Glichev and professor V. K. Fedyukin.
The quality index depends on the relative quality index and the relative volume of a certain type of product. The defect index depends on the defectiveness factor of the n-th product and the weighting coefficient of a certain defect. The contribution of each i-th type of product to the defect index is shown in the diagram in the form of a circular sector.
Key words: quality, evaluation, defectiveness, index, coefficient of weight, central angle
