The objective of the new model based controller is to assure the desired surface roughness by adjusting the machining parameters and maintaining a constant cutting force. It modifies the feed rate on-line to keep the surface roughness constant and to make machining more efficient. The control model was developed based on simplified models of the turning process and the feed drive servo-system. The experiments were performed to find the correlation between surface roughness and cutting forces in turning and to provide functional correlation with the controllable factors. Simulation setup and results are presented to demonstrate the efficiency of the proposed control model. In terms of surface roughness fluctuations and cutting efficiency, the suggested control model is much better than a conventional CNC controller alone. Integrating the developed control model with the CNC machine controller significantly improves the quality of machined componentsCilj članka je predstaviti modelno podprt sistem vodenja struženja s pripadajočim simulacijskim blokovnim diagramom. Namen na modelu temelječega sistema vodenja je zagotavljati želeno hrapavost obdelane površine s sprotnim prilagajanjem rezalnih parametrov in ohranjanjem konstante rezalne sile. Sistem z dinamično adaptacijo podajanja obvladuje hrapavost površine ter rezalne sile na struženem nožu. Namen izdelave predlaganega sistema vodenja je poiskati omejitve takšnega principa vodenja. Modelno podprt sistem vodenja je izdelan na osnovi poenostavljenega modela procesa struženja in podajalnega servo-sistema. Celotni sistem vodenja se sesoji iz modela napovedovanja rezalnih pogojev, referenčnega bloka, bloka vodenja, procesa odrezavanja, CNC servosistema, elementa za korekcijo podajanja in senzorja, ki meri izhodno veličino procesaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
