AB  - This study examines the possible utilization of machine learning and decision-making in the woodworking sector. This refers to the recognition of certain sounds produced during tool idling. The physical and geometric properties of the circular saw blade result in different noises being generated during idling. It was assumed that the respective circular saw blades can be recognized by these noises. The noises of three different circular saw blades were examined while idling at the same speed. In order to obtain useful data for the deep learning process, the coarse signals were subjected to frequency analysis. A total of 240 noise samples were taken for each circular saw blade and later subjected to signal processing. Frequency-power spectra were created using a custom program in Matlab Campus Edition software, such as for the spectrograms. A short Fourier transform was used to create the average spectral density plot using self-made software. The input data for the deep learning network was created in Matlab using a custom program. The GoogleNet deep learning network was used as a data classifier. After training the network, an accuracy of 97.5% was achieved in recognizing circular saw blades.

AB  - Non-contact process monitoring could be a powerful tool to prevent tool misuse, detect wood species, detect tool dullness and reduce electrical energy consumption-all of which could reduce production costs. The aim of this study is to identify recognizable patterns in the sound signals produced during the circular sawing of two different wood species-beech (Fagus moesiaca) and fir (Abies alba)-and to classify them in order to obtain an intelligent machining process capable of recognizing the wood species being machined. These two wood species were selected for this study due to their morphological, physical and mechanical differences. The cutting power was also recorded during the process and measured indirectly via the motor power used. A sound signal can easily be converted into an image (spectrogram), which is suitable as a data basis for the deep learning process. Several neural networks were used to classify the sounds. In order to prepare the raw audio signal for machine learning using image recognition, it was processed in several steps. The relationship between the audio and the recorded cutting power was also investigated and found to be strongly correlated, but only for audio frequencies up to 4500 Hz. Based on the results and further analysis, the classification accuracy for wood species identification varied between 98% for MobileNetV2 and 94% for the InceptionV3 deep learning network.

AB  - There is an increased research interest in methods for transparent wood production and its use. Wood transparency could be achieved by its delignification followed by an impregnation process with polymers having proper optical properties. However, delignification processes are mainly time consuming and not environmentally friendly. The possibility of treating mahogany wood (Swietenia macrophylla King) with 20% hydrogen peroxide for 70, 100, 135, and 170 min at 103 degrees C is presented in this research. According to the treatment duration, lignin content decreased 40 to 94% relative to its initial content in the control samples, whilst the cell structure remained intact. Due to the light scatter effect, caused mainly by wood tissue structure, the direct optical transmittance of treated samples in the visible light spectrum (400 to 800 nm) was less than 40%. Simultaneously, the total optical transmittance of samples treated for 100 and 135 min reached values between 70 to 80% with high values of the haze at approximately 30 and 60%. Optical transmittance in the visible spectrum area of the samples treated for 170 min was from 45 to 80% and the haze from 25 to 45%.

AB  - As Serbia is currently dependent almost entirely on its own forest resources, consumption of raw wood biomass, for all purposes, should be limited within current boundaries, about 9,000,000 m3. This situation requires from the wood processing industry to be responsible for the raw material and to reduce energy consumption and environmental pollution at all stages of the life cycle to a minimum. This also applies to the production of wood pellets, which are considered as a (nearly) purely renewable fuel and one of the potential substitutes for fossil fuels for heat production. The attention of this paper was paid to the wood pellet production, because this segment has the greatest impact on overall energy consumption and the influence on the environment in wood pellets life cycle. For the necessary calculations the “GHG Balance of Pellet Production” program with some upgrades, was used. The analysis showed that the investigated Serbian pellet plants, for different reasons, used more raw material and energy for production of 1 ton of pellets than plants elsewhere in Europe and America. In order to change this situation several different improvement methods have been examined and appropriate solutions suggested. The analysis of possible solutions showed that, if the proposed measures were implemented, the possible raw material would be between 7 and 10%. The analysis of possible solutions showed that, if the proposed measures were implemented, the following savings could be achieved: savings in wood raw materials between 7 and 10%, energy savings 12% and reduction in greenhouse gas emissions 23–45%.

AB  - A sound or a noise that accompanies wood machining processes is introduced by the tool rotation itself, by the friction of moving machine parts, or by wood-tool interaction. The sounds generated during machining with a circular saw could be analysed in order to monitor and possibly control the cutting process. Applying altered cutting parameters while cutting beech wood (Fagus sylvatica L.), which is the most common wood species in the Republic of Serbia, caused acoustic emissions that could be analysed throughout corresponding spectra. As shown in previous studies, altering the cutting parameters, e.g., the feed speed and tool override, resulted in variations in power consumption, surface roughness, and acoustic emission (or acoustic pressure). The aim of this paper was to provide a possible correlation between the applied cutting parameters and the acoustic emission spectra with respect to consumed power and the state of the machined surface. Along with acoustic emissions, the power consumption and surface roughness data were also acquired in order to make a possible relationship. By associating the idle circular saw acoustic spectra with background noise and comparing them with those obtained during machining, it was possible to indicate spectrum areas of particular interest for further analysis.

AB  - A three-dimensional model is proposed to describe the heat and mass transport process in the convective drying of wood with microwave heating. The model is based on the conservation of mass and energy and uses parameter values from the literature. Experimental results obtained for temperature profiles during the drying of wood samples are compared with model results. Satisfactory agreement is obtained over a range of drying air temperatures, moisture content, and velocities. It is concluded that higher microwave power results in larger exchange potentials, leading to the evaporation of water from wood. By increasing microwave power, the moisture within wood can absorb more energy and result in higher temperatures and evaporation rate.

AB  - Two measuring methods (direct and indirect) for peripheral milling cutting force, with the aim of machinability examination of the oak wood, are presented in this paper. Extensively research was performed with over 450 measurements of cutting forces and cutting power. Measurements were conducted for different cutting depths, feed rates and cutting tool geometry. Very strong linear dependence between the peripheral cutting forces calculated upon model values of cutting power (F-om*) and peripheral milling force model values (F-om), was established by the means of comparative analysis. Latter is proved by high value of determination coefficient, which amounted to 0,92. Furthermore, it has been proven that there is the same trend for both measuring methods of peripheral forces, taking into consideration that direct method results show average 23% higher values than those gained using indirect method.

AB  - More advanced approach in the wood machining requires constant monitoring of the cutting process in real time. Such techniques can be provided by measuring different process outputs. The amount of heat generated during cutting, cutting forces, power consumed are common examples of cutting process output. The specific construction and the shape characteristics of the circular saw indicate possible relationship between the power consumption, acoustic emission and the cutting process progress. The results obtained in this paper for the power consumption and the acoustic emission spectrum analysis strongly suggest dependence of the former to the tool override. The intention of this paper is to compare the results obtained from already existing, but slightly altered, technique of the power measurement and one still developing, the sound analysis. The actual environmental conditions performed in the research, incorporating auxiliary systems, such as exhauster installation, had to bring the results of the conducted research to the point of practical implementation. The utilization of the acoustic emission analysis as an instrument for fast determination of the consumed power during circular saw cutting of the laminated particle board might become powerful indicator of the state of materials involved in the cutting process, both the tool and the wood based board. The results presented would clearly indicate the possibility of such implementation of the frequency and spectrum sound analysis.

AB  - The commonly employed conventional dry kilns achieve the desired changes in wood moisture content with their hardware sub-systems and properly chosen drying schedules, which determine the required times depending on the value of the humid air parameters. Drying kilns predominantly make use of subsystems providing dehumidification, humidification, and heating. Optionally, some other variables, such as air flow, can also be controlled. The operation of each of the mentioned subsystems can be described in terms of the physical processes of heat and mass transfer. Variation in the process parameters (air humidity and temperature), previously defined by the chosen drying schedule, might result in instabilities in the integrated system. In order to examine such possibilities, a simulation was performed using a mathematical model and the corresponding matrix transfer function with the aim of determining the system's stability and the conditions to attain this in terms of the control laws.

AB  - A more profitable application of wood-based composites would certainly include the possibility of their use as a dielectric material in the form of electrical insulation. The profitability and the price difference between materials normally used for these insulating purposes and those based on wood would easily justify the interest to study the dielectric properties of such composites. There is another reason why an extension in use of these composites might become important. It originates from the general shortage of high-quality wood. Thus, the related properties of hardboard and medium-density fiberboard were investigated as well as plywood and particleboard. The modifications included treatments by direct current plasma glow discharge, vacuum, conditioning of samples at room temperature for prolonged periods of time, and their combinations. A relationship was discovered between the applied treatment procedures and the investigated dielectric parameters. The comparison between the treatment effects indicates those most convenient for the purpose of production of electrical insulating and also assists in differentiating which treatment processes lead to improved properties of the investigated wood-based composites.
