Bionski sistemi v industriji (BAS Bionic Assembly System)
Spreminjanje proizvodnega okolja, za katerega so značilne agresivna konkurenca na svetovni ravni in hitre spremembe procesnih tehnologij, zahteva ustvarjanje novih proizvodnih sistemov, ki jih je mogoče enostavno nadgraditi in v katere se lahko nove tehnologije in nove funkcije zlahka vključijo. Da bi se odzvali na te nove zahteve, na kratko predstavljamo Bionic Assembly System (BAS).

Nekateri tehnološki izzivi Industrije 4.0
Industrija 4.0 (I 4.0), pametne tovarne, pametni izdelki itd. so v zadnjem času tema, o kateri se veliko razpravlja na različnih nivojih družbe v Evropi. Proizvodni procesi, ki bodo krmiljeni s pametnimi mrežami in pametnimi sistemi, bodo imeli v prihodnje velik vpliv na naše življenje in na družbo v celoti. Pametna proizvodnja bo vodena s pomočjo inteligentnih programskih orodij, ki bodo povezana s pametnimi orodji in stroji ter napravami.

Testing the impact of light conditions on image quality for optical inspection of surface defects
Contactless and automated optical inspection tools make headway in comparison to tactile methods in modern factories. In order to develop an advanced optical tool for inspection of metal components produced for the automotive industry, one faces a number of challenges.
A setting of accelerometer’s parameters for prevention of impacts and movements of washing machines at low rotational speed of drum
Nowadays, vibrations are listed as among the most difficult challenges in the research and development of washing machines. This paper shows the method and procedure of setting up parameters for improvements of the performance of the washing machine by implementing the accelerometer.
A nonlinear model of positioning electrohydraulic servo drive
The highly nonlinear nature of the electrohydraulic servo system is well known. The main reasons for nonlinear and non-differentiable mathematical descriptions of systems dynamics are fluid compressibility, leakage flows, friction forces, and nonlinear fluid flow through servo valve orifices.
