Abstract:

The problem of improving the ecological and industrial safety of the technological processes of metalworking by cutting has been studied. The relation between ecological parameters and technological process parameters has been shown. The issues of forecasting vibration levels in the structure of metal-cutting machines using automation aids have been discussed. An algorithm has been suggested that offers forecasting vibration in machine elements based on vibration measurements in one point where a sensor is installed.

Problem. Specially created regular surface reliefs strongly influence the reliability and operational properties of machine parts. One of the effective methods of obtaining reliefs is cold plastic deformation (CPD).

However, to date, there is no systematic study of the formation of reliefs by CPD methods, especially with the use of linear indenters. Goal.

This article considers the possibility of increasing the efficiency of end milling by using a modified lubricating-cooling technological medium, based on a water-miscible cutting fluid. The conditions for the effective use of modified coolant in processing stainless steels ensuring a decrease in cutting forces and therefore a decrease in vibrations, which contributes to an increase in the quality of manufactured products have been determined. A decrease in cutting forces is due to the presence of oleic acid in the modified cutting fluid, containing surfactants, forming a dense lubricating film

Abstract In current conditions, great attention is paid to the quality of parts, which is in many ways determined by finishing operations of mechanical treatment, with surface grinding being the most widespread.

Abstract:

In order to enhance the tool life of hot forging dies, increasing the wear resistance of the forming tool surface is of great importance. In addition to thermal and thermo-chemical surface treatments, methods applying thin wear-resistant coatings gain more importance. Therefore, ceramic-based mono- or multilayer hard coatings are used in combination with a supporting nitride layer. Due to their low material-specific thermal conductivity, ceramic coatings have an increased sensitivity to abrupt temperature changes. To avoid such thermal shocks, an adjustment of the cooling behaviour is required

AbstractThe deformation of a part occurring in the process of grinding directly influences its exploitation and quality parameters. The instability of shape and size, which occurs due to an imbalance of residual stress, can be the one of the major causes of deformation of a part. The decrease in stress slows down the deformation process. Considering the regularities of heat source intensity dependence on the grinding modes, it can be asserted that with increasing grinding depth and grinding wheel hardness, the value increases and it decreases with a growth in a speed of the part and the use of

Abstract:

This paper investigates a special case for scheduling of the multi-crane operations in batch annealing process in an iron and steel enterprise so that the completion time of the last annealed coil (makespan) is minimized. Additional no-delay and no-buffer constraints for taking fully advantage of machines are considered. No-delay constraints for machine unloading means technological requires fixed heating time and cooling time that once the heating (cooling) is completed, the furnace (cooler) must be unloaded immediately without any delay by crane.

Abstract:

Minimum Quantity Lubrication (MQL) has been proved to be an efficient lubricant technique in machining that increases tool life, improves surface roughness, facilitates the recycling of the resulting chips, brings more sustainable practices in terms of minimum use of lubricants, and reduces the operators’ exposures to toxic particles with respect to conventional cooling practices. In order to increase the performance of MQL, nanoparticles of Al2O3, MoS2, SiO2 graphite and graphene among others have been recently introduced into MQL lubricants. This new approach, called nanoMinimum Quantity Lub

One of the main indicators of internal combustion engines, tractors and the machine-tractor unit as a whole it's the power. It can change in the process of operation and there comes a time when subsequent use is inadmissible or inexpedient. In such a state, it is appropriate to apply technology to improve this indicator and reduce the fuel or lubricant consumption. The power parameter of an agricultural power machine is essential to achieve high productivity with low operating costs with minimal environmental pollution. The monitoring of changing the power is generally carried out by equipment

Abstract The cooling rate is one of the main tools available to the process engineer by means of which it is possible to influence the crystallisation process. Imposing a desired microstructure on a casting as early as in the casting solidification phase widens significantly the scope of technological options at disposal in the process of aluminium-silicon alloy parts design and application. By changing the cooling rate it is possible to influence the course of the crystallisation process and thus also the material properties of individual microstructure components.

Indication of the proper scope of application of high-speed steels (HSS) produced by conventional methods and powder metallurgy for cutting tool blades requires a thorough assessment of their properties in various cutting conditions. According to common knowledge, the properties of tools made of both types of steel are largely determined by the arrangement of carbide phases. It turns out, however, that the surface morphology of the cutting blades is at least as important for their operational properties.
