AB  - An advanced flexible programming methodology for CNC woodworking machines was developed. As the research starting base, a three-axis CNC woodworking machine was used. The developed methodology is proposed for programming, simulation, postprocessing, and machining by woodworking machine. This flexible programming method integrates the standard programming based on CAD, CAD/CAM systems, and STEP-NC protocol through different output files, enabling data interoperability during the realization of the machining tasks. The control system for the machine is configured based on the open-architecture software LinuxCNC to verify the flexible programming method and the results obtained. Programming verification was realized by simulation on a configured virtual machine in different programming environments and finally on a virtual machine integrated with the control system. The results obtained from the study were evaluated comparatively.

AB  - This study proposes a reconfigurable open architecture control system for the Computer Numerical Control (CNC) woodworking educational machine tool called "EMCO F1 CNC". On this machine physical hardware reconfiguration (spindle position can be vertical and horizontal) is possible. The idea was to develop a control system that would follow the configuration changes of the machine tool. The educational character of the machine and its reconfigurability demand possibilities for machining programme simulations in order to determine optimal workpiece position in the workspace and programme verification. Those are the reasons for developing a virtual machine tool integrated with the control system as a digital twin. The study presents a novel methodology for the development of control systems, merging the concept of "virtual commissioning" with iterative error-driven processes. The objective was to develop a dynamic control system capable of promptly adjusting to kinematics changes in real time. In a wood machining experiment, a test workpiece for machine tools for both machine configurations verified the operation of the developed control system.

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  - 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  - The influence of log diameter and log quality were studied relative to the potential heat energy produced from wood residue. Research was conducted on beech sawmill logs (30 cm to 49 cm in diameter and 4 m in length) of different qualities. Logs with greater diameters and of better quality increased the amount of products and decreased the amount of residue. A decrease in the diameter and quality of beech logs increased the total energy capacity, ranging between 840 kWh/m(3) (highest quality logs, 40 cm to 49 cm in diameter) and 1,350 kWh/m(3) (lower quality logs, 30 cm to 34 cm in diameter). Drying the lumber produced from logs of small diameters used less than 10% of the potential heating energy. However, logs of 40 cm to 49 cm in diameter increased this usage to 33%. When burner losses and drying energy losses were calculated, there was approximately 430 kWh/m(3) to 960 kWh/m(3) of leftover energy. This could be used for various purposes or it could be sold. The amount of obtained energy was influenced more by log diameter than by the log quality.

AB  - This paper presents the results of poplar (Populus x euramericana) veneer colour change caused by one-hour long thermal treatments at temperatures of 190, 200, 210 and 215 C. There were three veneer zones included in this experiment: Veneer from sapwood, veneer from heartwood and veneer from intermediate zone - mixed. The measurement results by CIELAB colour system confirmed that there were significant colour differences among the three groups of veneer before thermal treatments. Of all thermal treatments, only the treatment at 210 degrees C contributed to a significant decrease in difference of colour among of all observed veneers. Based on more intensive color change in veneer formats from sapwood, it could be assumed that there were differences in chemical composition between the peripheral and core zones of poplar wood.

AB  - The paper presents the research of differences in quantitative and value yields, and structure of sawn timber and residues, whose appearance is caused by different methods of sawing beech logs with red heartwood. In order to achieve the goal, 45 logs were divided into three even groups and sawn into commercial timber using three methods: round, cant and live sawing. Similar quantitative yields were found for round sawing and cant sawing (60.63 % and 60.52 %, respectively), while a lower result of 56.79 % was observed for live sawing. Less timber ( edged and red heartwood boards) and smaller products were found in live sawing than in other two methods, meaning that live sawing resulted in a lower value yield.

AB  - The paper presents results of techno-economic analysis of using wood residues from wood industry for CHP (combined heat and power). The aim was to determine the economic feasibility of CHP in Serbia in the light of newly adopted feed in tariffs. In the first part, costs of electricity production are calculated for five different types of CHP technology which could meet the needs of wood industry in Serbia. In the second part of the paper, sawmill wood processing and pellet production were taken into consideration. First, we found that the installation of CHP in small capacity sawmills (about 10,000 m(3)/year) is not economically justified. The main reasons are high investments in micro CHP (up to 100 kW(el)) per kW of power. Second, the approximate electricity production costs in the potential CHP installations in pellet factory with capacity about 50,000 tonne per year is only slightly lower than the offered purchase price. However, advancement in CHP technologies and increase of the number of implemented projects should lead to a drop of equipment prices. Regardless of the price increase of raw materials and labour, this drop will have a significant impact on the reduction of total costs of electricity generation with CHP becoming more attractive to investors.

AB  - Wood biomass has got its place in the energy balance of Montenegro. A little more than 6% of the total energy consumption is obtained by burning wood. Along with the appropriate state measures, it is economically and environmentally justified to expect Montenegro to more than double the utilization of the existing renewable energy sources including wood biomass, in the near future. For the purpose of achieving this goal, "Commercial Utilisation of the Wood Residue as a Resource for Economic Development in the North of Montenegro" project was carried out in 2007. The results of this project were included in the plan of the necessary interventions of the Government and its Agencies, associations or clusters, non-government organisations and interested enterprises. The plan was made on the basis of the wood residue at disposal and the attitude of individual subjects to produce and/or use solid biofuels and consists of a proposal of collection and utilisation of the wood residue for each individual district in the north of Montenegro. The basic factors of sustainability of future commercialisation of the wood residue were: availability of the wood raw material, and thereby the wood residue, the development of wood-based fuel markets, and the size of the profit.
