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). This method of modification does not lead to the occurrence of significant stresses in the material of the part and can be form-forming. The latter is important in repair production. 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 a novel approach for guiding elements of sawing machines wear resistant coatings were applied on open-porous AlSi7Mg substrates by means of high velocity suspension flame spraying (HVSFS). The challenge is to establish a wear resistant coating but simultaneously maintain the open-porous structure that is necessary to serve as a permeable structure for liquid cooling or lubricant media under operation. In a first approach, a water-based suspension containing a mixed Al2O3-TiO2 powder for HVSFS was used to deposit dense and well adherent mixed-oxide coatings. As the substrates exhibi

An effective means of studying lubricant film rheology within EHL contacts is by detailed mapping of the temperature of the fluid and the bounding surfaces within the lubricated contact area. This provides a way of directly measuring the rheology of lubricant films under true EHL conditions. Furthermore, temperature measurement itself provides a very effective means of testing and validating computer simulations. In the current work, the experimental approach initially developed by Sanborn and Winer [1] and then by Spikes and co-workers [2], has been advanced to include a high specification in

Abstract The waste management and practice of reuse of cooling lubricant containing grinding swarf has become a problem of rising importance due to introduction of the law of recycling economics in October 1996. Grinding swarf is a significant set of arising residual material in the metal working industry (about 250.000 t/a). The recycling of this material on the highest extent was object of researches carried out by a working group at the IWT together with the IFAM, accompanied by the Federal Environmental Agency.

The 12-stage FZG test (A/8,33/90) was originally developed to determine scuffing load capacity of engine oils [1]. During each load stage, the test is started at the same initial sump temperature. Heat of friction generated during a load stage results in a temperature increase of the lubricant. Final sump temperatures as high as 140 °C are often reached after the final load stage (Load Stage 12). A modified version of the test, (A/2,76/50) is used for laboratory determination of open gear grease performance [2]. In open gear lubrication, typical gear operating temperatures are in the range 50°

Aerothermal prediction for the high-pressure turbine is challenging because of the complex environment that interacts with the turbine: hot-streak migration, unsteady flow phenomena, fluid/solid thermal coupling and technological details (squealer tip, coolant ejections, fillets, etc.).

Abstract Lubrication of gear tooth is necessary for cooling as well as reducing friction losses. It is, however, difficult for rather high speed gear because both rotation of the gear itself and associated aero motion interferes the lubrication. In Addition lubrication consumes excess energy due to such kind of churning. To realize efficient lubrication it is worthy to feed lubricant from both ends of tooth in axial direction by the aid of sucking action of tooth spaces just after meshing. This probably make possible that the oil can reach the tooth surface as earlier as possible. Authors inve

We propose to focus in the present work on the effect of the number of the emitted jets on the generated heat transfer, in presence of an unchanged uniform crossflow.
