Experimental Evaluation of the Influence of the Train Control Valves Configuration on the Brake Wave Propagation DOI: 10.22184/2499-9407.2023.30.1.74.78
The paper discusses the issues of the automatic brake control system efficiency of a freight train. A hypothesis is put forward indicating the possibility of improving the current braking system of a railway car with some change in its configuration. Practical recommendations are given to improve the current braking system of railway cars and a conclusion is made about the possibility of introducing gas-dynamic process accelerators into the machine-tool industry.

Quality and Accuracy Increase of Aircraft Engine Parts Productivity on the Basis of Rational Application of Multi-Axis Grinding Machines with CNC DOI: 10.22184/2499-9407.2023.30.1.42.46
The developed technology of nozzle blades machining on a 5 axis CNC profile-grinding centre is presented. It increases productivity and quality of machining by increasing in quantity of machining surfaces of aircraft GTE nozzle blades from one installation, and also application of new highly porous grinding wheels and rational regimes of depth grinding. Combined use of machine tool NC system and special software to correct errors of parts casting surfaces during their installation, turning and depth grinding of base surfaces is considered.

Mathematical Model of the Technological Process of Deep Drilling DOI: 10.22184/2499-9407.2023.30.1.52.56
This paper presents an analytical mathematical model of a dynamic deep drilling technological system. The mathematical model was created on the basis of differential equations for the purpose of controlling an object – a technological drilling system. The control is carried out along the channel of the longitudinal feed of the tool, along the axis of the drill.
