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  - Za razliku od mekih vrsta drveća, podaci o dužinskom nastavljanju tvrdih lišćara su veoma oskudni. Cilj ovog rada je da se ispita uticaj šeme opterećenja na savojnu čvrstoću bukovih gredica nastavljenih pomoću klinasto zupčaste veze. Sa stanovišta konstrukcije klinasto zupčasti spojevi predstavljaju osnovni način dužinskog nastavljanja gredica prilikom izrade lameliranih elemenata. Ispitivanje savojne čvrstoće dužinski nastavljenih gredica od tvrdog drveta na teritoriji Srbije gotovo da nije ni vršeno. Ispitivana su dva profila klinasto-zupčastih spojeva u skladu sa DIN68140. Klinasto-zupčasti spojevi su izrađivani po boku i po stranici gredica. Uzorci nastavljeni po dužini opterećivani su i po boku i po stranici. Na osnovu dobijenih rezultata došlo se do zaključaka da pravac opterećenja, površina lepljenja kao i položaj spoja utiču na čvrstoću dužinski nastavljenih gredica.
AB  - Limited information is available on end gluing hardwoods in contrast to softwoods, which have been extensively investigated. The objective of this study was to examine the influence of bending pattern on bending strength of finger jointed beech wood. In structural uses finger jointing is finally the major method to end joint timber for the production of glue-laminated elements. There are no bending strength experimental results for finger-jointed hardwoods for investigations conducted in Serbia. Two finger jointed profiles were studied in accordance with DIN68140. The finger joints were made by side and by face of beam. Length jointed samples were loaded at the side and in the face. The obtained results led to the conclusion that the direction of load, gluing surface and the position of joint influence on the strength of continued longitudinal beams.
