“…Although the primary task of such systems is to control the parameters of the technological process, they still have the accumulation of information, the analysis of the available experience, even the prediction of certain events, for example, repair work [2]. It tools demonstrate good applicability for successfully solving problems in the production of iron, iron ore sintering and the hot strip rolling process with regard to process control or product quality [3]. The development and integration of monitoring, diagnostic and forecasting technologies (collectively known as PHM) can improve maintenance and control strategies in production operations [4].…”

The study divides the analysis of monitoring and diagnostic information, leaving for monitoring the parameters of the stationary process, and for diagnostics -various transient regimes in the technological process. This, in turn, divides the algorithms of information processing into control of the output from the given boundaries for stationary parameters and the classification and prediction for dynamically changing parameters in a multidimensional space. In view of the large number of monitoring and diagnostic information, as well as due to different algorithms for processing it in an appropriate information system, it is necessary to apply multi-dimensional analysis methods. As diagnostic influences, various jumplike changes of a "natural character" are used, and the state of the equipment allows judging the apparatus of the influence functions. The abrupt changes in the technological process are reflected in the change in its parameters. The reaction to them is weakened as they are removed in accordance with the influence functions. The values of the parameters at the moment of the reaction define a point in the multidimensional parameter space and allow one to relate the state to one or another standard, and to relate the corresponding management algorithm to the standard. The experimental model includes five links simulating the operations of the technological process, a pulsed signal source simulating a step change and five links of propagation delay simulating the duration of operations. The results confirmed theoretical conclusions about the influence functions.

“…During the measuring period, the average temperature, wind velocity and cross-sectional area of flue gas in the stack were 142.5 °C, 12.23 m/s, and 25.44 m 2 , respectively, and total air The basic principle of air leakage detection on sintering pallets is according to the sound field analog equations of gas leakage, shown as Eqs. (3) and (4). It could be known from the formula that the sound pressure (P) of air leakage is proportional to the leakage aperture (D), that is, the air leakage is larger when the sound pressure is larger.…”

CFRP (carbon fiber reinforced plastic), which is composed of carbon fibers in a resin matrix, is an extremely strong and light composite material that has found use in the aerospace and automotive industries. CFRP boards are very difficult to machine using common machining processes. Various machining artifacts, such as burrs and delamination, occur frequently when machining CFRP. Adequate techniques for machining CFRP have not yet been established. Recently, electroplated diamond wire machining technology has found use in cutting hard, brittle materials such as silicon and sapphire. In this study, we used an electroplated diamond wire saw to cut a CFRP workpiece. We quantified the cutting forces imposed on the workpiece and observed the surface state of the workpiece after cutting. We demonstrated that an electroplated diamond wire tool is suitable for the high-quality machining of CFRP boards.

A mathematical model of the dynamics of changes in the state of security indicators of control and diagnostic data on the technological process is proposed. It is constructed using Markov chains and takes into account the probabilistic-temporal mechanism for changing the state of data protection indicators of this class. Based on this model, a methodological approach has been developed for multi-criteria assessment of the security of control and diagnostic data on the technological process. The approach is based on the analysis of current deviations of the values of data protection indicators from the requirements for them, takes into account and eliminates the uncertainty of the initial diagnostic information. The proposed methodological approach also allows one to take into account transients that affect security when introducing control over the structure, parameters and modes of collection and processing of control and diagnostic data about the technological process in various conditions.
