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 paper presents the results of investigations performed in the peripheral milling of oak wood (Quercus robur), where the impact of cutting regime elements and tool geometry on the cutting force is analyzed. A large-scale experiment was conducted to implement the obtained results in developing a reliable analytical and simulation model for analyzing and predicting the cutting forces, depending on the feed rate, the milling depth and the tool rake angle. The generated mathematical model is adequate and describes accurately enough the dependence of the cutting forces upon the selected impact factors in the adopted test conditions. The evaluation of the model parameters significance indicates a significant impact of feed rate and milling depth, whereas tool rake angle does not show any significant impact in this case. The developed mathematical model can be employed in manufacturing conditions as an indicator of wood and wood-based materials machinability.

AB  - The aim of investigations was to determine whether the tested models for calculating forces in wood cutting, set up under strictly controlled laboratory conditions, can yield sufficiently accurate results for predicting wood behavior in real cutting conditions. Tests were carried out on oak wood (Quercus robur). On the basis of measured values for the required cutting power, cutting forces were calculated and used for comparison by applying the method of coefficient (Kreljak's model) and Axelsson's model. The analysis indicated that there is not a result, but there is similarity in the curve shape, i.e. changes in measured values are followed by corresponding changes in calculated values. It can be inferred that analyzed models are not suitable for the cutting forces quantification, but could serve for comparing different cutting modes. More accurate modeling of the cutting process requires, besides physical, wood mechanical properties as well.

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 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  - U radu su prikazani rezultati uticaja termičke modifikacije na snagu rezanja potrebnu za glodanje drveta. Eksperiment je izveden za različite temperature tretmana (170°C, 190°C i 210°C) i različite tehnološke parametre obrade (pomak i dubina glodanja). Snage rezanja tokom glodanja merene su na četiri grupe uzoraka bukovog drveta dimenzija 35×16×400 mm, posebno za srčevinu i beljiku. Za obrađene uzorke testirana su mehanička i fizička svojstva drveta: savojna čvrstoća, modul elastičnosti pri savijanju, poprečna i bočna tvrdoća i gustina u prosušenom stanju vlažnosti. U ispitivanju je korišćen merni uređaj za merenje, praćenje i prikazivanje snage rezanja, razvijen u Centru za mašine i uređaje na Šumarskom fakultetu u Beogradu. Rezultati ukazuju na postojanje razlika u snagama potrebnim za obradu termički obrađenog drveta u odnosu na netretirano drvo. Utvrđeno je da sa povećanjem temperature tretmana potrebne snage rezanja opadaju.
AB  - The paper presents results of influence of thermal modification on cutting power required for milling wood processing. The experiment was conducted for the different treatment temperatures (170°C, 190°C and 210°C) and different technological parameters of processing (feed and cutting depth). Cutting powers during milling were measured on four groups of beech wood samples, dimensions 35×16×400 mm, separately for heartwood and sapwood. The following mechanical and physical properties of the processed samples were tested: bending properties (modulus of rupture and modulus of elasticity), cross-sectional and tangential hardness, and air-dry density. The measuring device used for measuring, monitoring and displaying cutting power was developed at the Wood Machining Centre at the Faculty of Forestry in Belgrade. The results point out the differences in the powers required for processing heat-treated wood compared to untreated wood. The analysis shows that with the increase in treatment temperature, the required cutting powers decrease.

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.
