“…To simplify the analysis, we proceed to the centered variables decomposing y(t) into a constant component у <y(t)> and deviation x(t). In this case the dependence (5) (11) In the equation (11) y(ti) and <y(t)> serve as deterministic functionals, x(t) defines a stochastic process. We present a stochastic process in the form of a stochastic function defined by the Langevin equation [14].…”

The article considers the estimability of the deviations of actual output variable values from the forecast ones in the system for monitoring the process of external round grinding. The author proposes the method for determining the deviations and establishing their most probable values as well as for establishing the cause of such output variable value deviations and technological system changes. It is substantiated that the determination of the output variable deviations and the parameters of the technological system state is possible at the control of the output variable change rate as the interruption time intervals are different for different subsystems. The authors managed to determine the dependences of the deviations of actual values (t) from the estimated ones yр(t). To resolve the objective of identifying the causes of output value deviations from the forecast ones, the authors applied the method for determining the indirect measurement errors. The obtained dependences made the authors draw the conclusion that at the control of the change rate of output variable values one is able to find out the disturbance type and the type of the deviation of output variable actual values in the technical system. This provides for the opportunity to correct the control of the external round grinding process as well as to calculate the time intervals at which one needs to take into account some or other changes in the technological system.

“…The model takes into account the peculiarities of the stochastic nature of the abrasive processing process and the interaction of additional physical processes and technological factors. In paper [35] authors were proposed a model is based on the probabilistic approach and it allows calculating the value of the bond layer removed with erosive discharges and predict the state of the technological system at any moment. In paper [36] by authors was proposed improvement the contact performance properties, by submitting presentation of optimization of flat grinding of titanium parts by following two parameters: the relative bearing length of the profile and the relative bearing part of the parts' surface that allow assessing the quality of the surface at the microand macro-scale.…”

The intensifying of the manufacturing process and increasing the efficiency of production planning of parts are the first-priority task in modern manufacturing. The use of various methods for controlling the cutting force and temperature in cutting zone under cylindrical infeed grinding and studying its impact on the quality and accuracy of parts machining can improve machining efficiency. The peculiarity of the work is to the proposal to consider a fast-moving source like a heat source in the plunge grinding process. Based on the Peclet analysis, the further development of the method for calculating the allowance removed at each workpiece revolution by optimizing the cylindrical plunge grinding cycle parameters has been justified. The methodology for determining the optimal parameters of a cylindrical plunge grinding cycle, which based on a simulation of the dynamics of such a process represented by a three-mass model of a 3M151 circular grinding machine has been used in research. The practical value of the study lies in studying the ways of improving the grinding performance of the parts by intensifying cutting modes and optimizing the structure of machining cycles.Keywords: thermophysics of the grinding process, contact zone of the grinding wheel and the workpiece, grinding process dynamics, surface quality, defective layer

The paper analyzes the causes of failures of coarse crushers “KKD 1500-180” at JSC “Almalyk MMC”. It has been established that the most common cause of these failures is a drive shaft failure. Static analysis of the strength of the drive shaft was performed using Autodesk Inventor 2020 CAD software. A dangerous shaft section was found, and recommendations aimed at improving its operability were proposed.
