Opis:: Grinding is usually the last stage of the technological process and determines the quality of manufactured products. One of the varieties of grinding more and more often used in practice is deep grinding which is called Creep-Feed Grinding. It is characterized by a high value of grinding infeed and slow feed. Technological parameters such as the depth of grinding and the speed of feed have a significant impact on the quality of the workpiece. However, also the grinding speed has an influence on the grinding process and the result of machining. Therefore, experimental studies on the impact of grinding speed on the surface roughness and grinding force components were carried out. The tests were realized in the deep-grinding grinding process of Inconel 718 with a grinding wheel made of mixture of sintered alumina and ruby corundum.

Opis:: This article presents results of experimental tests of internal cylindrical traverse grinding in which the total machining allowance is removed in a single pass. Grinding wheels with zone-diversified structure made on basis of abrasive grains from Al2O3 were used in the process. Such tools are characterized by different construction of rough and finish grinding zones. Moreover, conic chamfer is shaped on their active surface that allows for even distribution of machining allowance on the grinding wheel surface. What is described in the hereby work is a device for precise shaping of conic chamfer on the grinding wheel active surface (GWAS). The work also presents results of tests whose aim was to determine the influence of grinding wheel macrogeometry on the process of internal cylindrical traverse grinding of internal cylindrical surfaces made from steel 100Cr6. Changes of selected parameters of the machined surface geometric structure (Ra, Rz, RSm, Rdq and RTp) and values of the grinding power P were analyzed. It was proved that the greater the conic chamfer width, the better the results.

Opis:: The following paper presents the analysis and synthesis of technological schemes, processes, tools and equipment for processing of conical gears and precession gears with medium module. As a result, a new method which allows to intensify the process of treatment, is proposed. It ensures a required accuracy of processing. The theoretical considerations are based on the theory of gear drives, theory of involute profiles generation and precession gears, generating machine, tool design theory and machine building technology. Methods of mathematical analysis, analytic geometry, mathematical model and 3D computer model are used. The experimental research was conducted in laboratories of the Departments of Machine Building Technology and the Department of Fundamentals of Machines Design at the Technical University of Moldova, by using machines and technological equipment for machining and testing. Experimental data processing was accomplished using approximation methods and mathematical statistics.

Opis:: The article presents the association of the output signals of the grinding process with the machining parameters. The article focuses on assessing the suitability of grinding force signal and acoustic signal acquisition for different process conditions. In the first part of the article the kinematic contact of abrasive grain with the workpiece analysis was carried out. By analogy to the micro-cutting process, geometric analyses are presented and the process parameters that have a major impact on the grinding zone load are indicated. Analytically it has been shown that elementary grinding speeds (wheel and workpiece speed) and grinding depth have a significant effect on recorded signal values. The work also presents a set of factors and phenomena that are sources of acoustic emission impulses in the grinding process. For a selected range of grinding parameters, an experimental verification was performed. The article presents the highly correlated relationship between grain penetration depth (maximum uncut chip thickness) and grinding force components, as well as the effective value of acoustic emission. The output signals of the grinding process were also compared, indicating the advantage of the acoustic emission signal above the grinding force in terms of the reaction speed (and lag) of the sensors to the phenomena occurring in the grinding zone.

Opis:: The article describes the role and types of cooling lubricants used in grinding processes. Conventional methods of coolants delivery into the grinding zone were described, such as: flood method, high-pressure jet method, centrifugal coolant provision method as well as methods method to minimize coolant flow rate: minimum quantity lubrication (MQL), minimum quantity cooling (MQC) and minimum quantity cooling lubrication (MQCL). Against this background, a methods were presented to completely eliminate grinding fluid from the grinding process (dry grinding) like: impregnated grinding wheels and cold air guns (CAG).

Opis:: One of the important and still current problems occurring in the fish processing industry is the intensive wear of the cutting surface of industrial cutting blades used to separate the fish raw material. In the paper, the proposes aproprietary solution to the above problem consisting in the regeneration of worn surfaces realized in the process of precise grinding by the use of a prototype 5-axis CNC grinding machine was presented. The obtained machining results were verified, among others on the basis of measurements of values of the cutting edges inclination angles and analysis of values of selected surface roughness parameters. The proposed solution along with the developed methodology can be an interesting alternative to typical ways of renewing the cutting ability of cutting tools in applications from the fish processing industry.
