Authors: Predein V V , Komarov O N , Zhilin S G 
Published: December 2020

Abstract
Casting production with aluminothermic method is one of the mainstream lines of production process designing and improvement in foundry practices. Cast blanks production methods based on thermite mixtures application provide economic benefits due to machinery and steel production plants waste (ferrous and non-ferrous chip scrap and scale) usage. Alloys resulting from exothermal reaction are used for cast blanks production. For minimization of expenses coming from power consumption, the oncoming cast blanks properties correction is conducted at initial stages to put them into operation immediately after production, which is achieved by adding fillers in charge materials to decrease reaction’s heating effect or by external heat supply. In some cases reaction’s high intensity and temperature lead to difficulties in final properties foreseeing therefore affecting the formation of repairable and irrepairable defects. Cast blanks with irrepairable defects are used as charge materials in further recasting in traditional melting units, which increases metal waste processing efficiency and non-wastefulness. Cast blanks with repairable defects are a subject to further processing. E.g., in case of chemical and structural inhomogeneity, high-rate internal stress, cast blanks are a subject to complex heat treatment, that allows bringing properties to the required level. Annealing is applied to achieve better homogeneity compared to as-cast condition. After heat treatment cast blanks contain granular pearlite or ferrite with various inclusions. It’s been established that high rates of alloying aluminium increase the high-carbon steels hardening temperature. After 1000°C hardening the samples have martensite structure with hardness index up to 628 HBW.

Published: December 2020

Abstract
In the modern world, the need to create high-quality goods and services and improve product quality comes to the fore. An effective method that many enterprises of the world have resorted to is the quality management system (QMS) in production. Implementation of QMS in the organizational processes requires both time and material costs and carries several problems that arise for managers. First, there is lack of interest on the part of management in QMS implementation process, which results in obstacles in the form of insufficient funding and staff resistance, as well as problems with staff motivation when introducing a new system and choosing a certification body. For the QMS implementation to bring the enterprise maximum effect, the manager needs to plan the implementation process in advance and develop actions to avoid these problems in the implementation process.

Published: December 2020

Abstract
Solid ceramic mills are a promising technological solution for cutting heat-resistant materials. Although nanostructured cutting ceramics has a number of valuable physical and mechanical properties providing high operational performance of mills, it has low strength. The design of a solid ceramic mills is formed by smooth surfaces without stress concentrators to ensure operability and to reduce the probability of failure. The most important structural element of solid ceramic end mill is a helical groove with a negative rake angle needed to increase surface strength. This groove can be machined with standard grinding wheels of type 1A1 or 1V1. However, the application of grinding wheels of a standard shape requires the use of reduced cutting parameters to prevent chipping on the forming sections of the cutter. Chipping can be caused by too short length of the contact line and the stress concentration at the end point of the profile of the grinding wheel, which is typically fully responsible for shaping the front surface and its transition to the tooth back. In this paper, in order to increase the contact line, we develop a new approach to designing grinding wheels for machining helical grooves of solid mills and determining rational technological and operational parameters for there use. A new approach is developed based on the fundamental principles of analytical geometry and linear algebra, numerical methods and basic axioms of the shaping theory. In this study, we have identified the key relationships between parameters determining the position of the grinding wheel relative to the workpiece and the geometrical parameters of a solid ceramic mills. The developed approach allowing to determine the specific design of the grinding wheel, depending on the initial parameters of the mill and the trajectory of the axis of the wheel relative to the mill, was implemented in the MathCAD environment.

Published: December 2020

Abstract
The article is devoted to one of the promising methods of increasing the penetrating ability of COTS into the zone of contact interaction between a tool and a workpiece and accordingly increasing operational characteristics of tool life by applying to the working surface fluorine-containing surface-active (FLUOR-SAS) from epilame solutions. Tribological tests were carried out using a special installation, where the test conditions are close to the conditions characteristic of the drilling process. Based on the results of the experiment, it was found that the effectiveness of epilamiting directly depends on the cutting speed, which determines the temperature in the contact zone.
Improving the quality of surgical scalpels with ceramic blades
Authors: Alisin V V 
Published: December 2020

Abstract
The article discusses the issues of increasing resistance to brittle fracture of surgical scalpels with ceramic blades from nanostructured crystals of partially stabilized zirconium dioxide. The statement is substantiated that the strength properties of crystals can be increased by increasing the crack resistance of crystals by alloying with rare-earth elements. The kinetic microindentation method is used to study the characteristics of mechanical properties and crack resistance of samples of alloyed crystals. An assumption about the efficiency of alloying crystals with cobalt is substantiated. The bending strength test of promising crystal compositions is carried out. Based on the study, recommendations are formulated on the use of zirconium dioxide crystals for surgical scalpel blade manufacture.
Research accuracy of final formation profile of rolling ball bearings by various methods.
Authors: Reshetnikov M K , Davidenko O Y , Shpilev V V , Zakharchenko M Y 
Published: December 2020

Abstract
An important role in the further operation of rolling bearings is played by the shape of the grooves of the ball bearing rings. That is why it is necessary to pay special attention to the formation of their profile. To study the shape of the trough, we studied a batch of ball bearing rings using the method of measuring the size of the stamps. Since the bearing also works with small radial loads, it is necessary to press in not only at right angles. Additionally, we propose to strengthen the effect of indentation. From the experiments it can be seen that there is a different distribution of stresses along the contact area for bearings of the same size. Based on this, it can be argued that the accuracy of the machining process is insufficient. Therefore, there is a need to improve the accuracy of shaping the profile of ball bearing rings by advanced technologies. To do this, we propose to use imitation completion. After this procedure, after conducting experiments, one can again see how the characteristics of the raceway profile of ball bearings have qualitatively changed, and, accordingly, their durability.

Selection and design of tools for finishing machining of seal grooves of hydraulic cylinders
Authors: Yatsun Elena , Zubkova Oksana , Karnaukhov Ivan 
Published: December 2020

Abstract
The most important operating performance parameters of machine components such as tightness, wear resistance, durability, and corrosion resistance largely depend on the state of their surface layer, determined by the parameters of machine processing during manufacturing. Selection of the technique for final machining of machine components is a rather difficult task, since, despite the large amount of information on technological support of the surface layer parameters, there are practically no recommendations on the quantitative estimates of the parameters of performance properties achieved in this case. Reliable functioning of hydraulic systems, their durability, and, consequently, reliable functioning and durability of the drilling rig, depend on the quality of the surface of the seal grooves. At present, turning is used for grooves machining, which in some cases does not provide the required quality indicators of the machined surface according to the surface roughness parameter. In this regard, an analysis of the possibilities of obtaining the required surface roughness using edge cutting machining techniques was conducted as well as other machining techniques ensuring uniformity of the surface roughness of seal grooves were analyzed. One of the promising processing techniques that can provide the required quality of the machined surface is a surface plastic deformation method. However, in order to use this method effectively, it is necessary to carry out an experimental study of the rolling process and determine processing conditions.
