Dynamic behavior of roller bearings under the loads can be described by a mathematical model. The dynamic bearing model is modeled using the finite element method. Analysis of the dynamic behavior of the radial bearing refers to the modal analysis, ie. the determination of the natural frequencies, the main forms of oscillation and damping for the considered bearing, with different values of the clearance. This analysis is based on the simultaneous analysis of excitation and response signals in the time domain or more often in the frequency domain. In addition to FEM, it was also performed the experimental test on a FKL 6006 bearing with different clearance values. Within this paper, a comparison of the results of the modal analysis performed experimentally with the results obtained by the finite element method was performed. The compared results show a satisfactory deviation.

As it is known, emissivity is paramount for accurate temperature measurement using IR thermography. The emissivity of metals is particularly interesting due to its variability in relation to surface conditions (surface roughness and oxidation state), viewing angle, temperature, and wavelength. In the frame of this paper, knowledge regarding metal surface coatings and its effect on emissivity has been gained in an effort to improve risk assessment of workplace burns arising from hot metal surfaces. The present study examined the emissivity of two-component polyurethane metal covering coat on steel and grey cast iron depending on temperature and coating thickness. It was concluded that metal coating leads to moderated metal heating and increases constancy of emissivity compared to uncoated metal surfaces.

Dentists and dental team members are exposed to an increased risk of large amounts of aerosols in the working atmosphere during clinical dental procedures. The analysis of the part of the aerosol that includes the finest particles of micro and nano dimensions is a starting point for understanding the relationship between exposure to aerosols and negative effects on the health of dentists. The paper presents the methodology and experimental realization of clinical sampling of micro and nano particles, from the aerosol generated during dental interventions, using a personal sampler.

Use of straight round bars is necessary in industries due to requirement of raw material as input for production of value-added products. Bars are often available in bent condition; hence straightening is a necessity before commercial use. Therefore, choosing a proper lot of straightened bars with acceptable level of residual curvature is a quality requirement. Use of statistical analysis by Factorial Design will help in decision making through appropriate Test Hypothesis for quality criterion of acceptable range of residual curvatures. This paper has made an attempt to look into the applicability of Factorial Design in bar straightening process.

Electrical discharge machining (EDM) is an unconventional machining process that can machine all electrically conductive materials, regardless of their physical and metallurgical properties. Due to the efficiency of machining modern engineering materials, existing EDM methods are constantly being researched and improved or developed. This paper deals with an innovative method that enables EDM machining of non-conductive ceramic material, named Assisting Electrode Electrical Discharge Machining (AEEDM). It combines electrical discharge machining with a hybrid assisting electrode. The aim of the study is to find the influence of pulse duration on surface roughness. For the set machining conditions, it was found that the surface roughness was increased by increasing the pulse duration. It should be emphasized that the supporting electrode method is used only in the electroerosion of electrically non-conductive materials.

Round bars produced in industries are often found compromised with degree of straightness. In many small or medium size industries the problem of straightness is often addressed somewhat manually, which is indeed a slow and cumbersome process and lacks quality and precision. To speed up the process, it is necessary to go for mechanized system i.e. deployment of straightening machine. However, straightening machine indeed helps in perfect processing of operation and quality aspects which can be systematically controlled through various parameters involved in the process. An attempt has been made in this paper to look into the effect of helix angle of the cross-roll arrangement in the process based on the equations developed by former researchers in this field.

The aim of this study is the analysis of the mechanical parameters on the tooth roots having different fillet radiuses in case of helical gears having modified teeth. These gear pairs are widely used in different engineering constructions because of the better load transmission and the more silent noise. Consequently, the development researches are determinable in this field. Designing of one helical gear is needed for the analysis. After that the creation of its CAD model is essential. This gear pair is analyzed by different fillet radiuses on the tooth root of the pinion. All of the other geometric parameters are unchanged. The applied moments are also permanent for each experiment. After the FEM analysis the received results and graph will be evaluated.

A certain percentage of mechanical parts in the engineering (parts in automotive industry, medical and measuring devices, parts in energetic sector, and etc.), refers to thin-walled structures with optimized shapes and dimensions. In addition to the requirements for a special shape of the structure, there are also requirements related to the dimensional accuracy and surface quality. In this paper, the milling of thin-walled tubular parts is analyzed. Workpiece of mentioned parts was C45E (AISI 1045) steel. Experimental analysis and optimization is based on Taguchi's experimental plan. The influence of cutting process parameters, depth of cut, feed per tooth and radial depth of cut, was analyzed. As the output cutting parameters, the dimensional accuracy and machined surface quality parameters, were measured and analyzed. Based on experimental data, modeling and optimization were performed. The obtained results defined the optimal input cutting process parameters, which give the best results in milling.

ABSTRACT One of the critical issues in remanufacturing strategy is determining the selling prices for the multiple differentiated versions of the new and remanufactured products. This study deals with such pricing decisions in closed-loop supply chains where the demand is assumed to be price- and reusability-dependent function with partially substitutable between different versions of the product. In light of the unique and practical demand function, the Salop spatial model is used to formulate the demand model where the consumer preference and the substitution effect are considered. The analytical and numerical results suggest that the prices of the new and remanufactured products increase in the similarity between multiple versions of the product. This study contributes to the literature by simultaneously considering the effects of pricing and reusability, yet the prior studies are neglecting such effects. Graphical Abstract

ABSTRACT In this article, an innovative hybrid optimization method is proposed based on the integration of the Artificial Bee Colony metaheuristic and the Dhouib-Matrix-TSP1 heuristic to overcome the tool path minimization problem. The proposed methodology consists firstly of providing different feasible solutions by implementing Dhouib-Matrix-TSP1 with several descriptive statistical metrics. Then, these solutions will become a part of the initial population of the Artificial Bee Colony that will perform this population in order to generate the optimal solution. To validate and compare the proposed method, several experimental instances of multi-hole making are simulated. The used dataset consists of four rectangular layouts and two circular layouts with an arrangement from 25 to 2600 holes. Results show that the proposed method outperforms the standard metaheuristics with an improvement rate between 0.24% and 9.35%. The obtained improvements concern simultaneously the minimal path length, the mean path length, and the SD of path lengths. Graphical Abstract
