Abstract:Kvaliteta obdelane površine in stroški obdelave sta glavna faktorja, s katerima podjetje dosega konkurenčnost na svetovnem tržišču izdelave preoblikovalnih orodij. Z uporabo najnovejših materialov in modernih postopkov obdelave podjetja poskušajo doseči optimalno izkoriščenost strojev in orodij ter si tako zagotoviti tržno prednost. Izbira rezalnih parametrov ima pri obdelavi velik vpliv na stroške, zato veliko raziskovalcev izvaja postopke off-line optimizacije. Na področju materialov se razvijajo vedno bolj kompleksni materiali, med katere prištevamo tudi gradientne materiale. Znane off-line rešitve optimizacij ne omogočajo zadovoljivih rezultatov pri optimizaciji rezalnih parametrov. V raziskavi smo razvili, izdelali in vpeljali v proizvodnjo orodij nov inteligentni sistem za korekcijo rezalnih parametrov pri frezanju gravur (ISK) za obdelavo standardnih in gradientnih materialov. Predstavljen sistem omogoča optimizacijo rezalnih parametrov v on-line načinu in izključuje negativne vplive človeškega faktorja v proizvodnjo. Z vizualnim nadzorom odrezka, obrabe orodja in merjenjem rezalnih sil sistem samodejno izvaja korekcijo rezalnih parametrov (vrtilne frekvence in podajalne hitrosti) ter tako omogoča optimalno izkoriščenost stroja, orodja in hkrati omogoča natančnejšo izdelavo. Raziskava zajema predstavitev problema, iskanje rešitev, sestavljanje in umerjanje sistema ter serijo preizkusov, kjer je sistem testiran v laboratorijskih in delavniških razmerah. Izdelan je tudi uporabniški vmesnik, ki na podlagi govornega vodenja operaterju stroja omogoča hitrejši odziv na nepredvidljive spremembe med obdelavo. V zaključku raziskave so podani rezultati, ki utemeljujejo in dokazujejo uporabnost sistema. Podani so tudi predlogi za nadaljnji razvoj in raziskave.

Title:INTELLIGENT SYSTEM FOR CORRECTION OF CUTTING PARAMETERS DURING MILLING OF TOOL ENGRAVINGS
Abstract:Surface quality and production costs for sheet metal forming tools are the main factors with which a company can achieve competitiveness on the world trade market. With the use of newly developed materials such as gradient materials and new cutting techniques, companies are trying to achieve optimal tool and machine exploitation and in doing so gain an advantage over other companies. Cutting parameters have a major effect on the altogether production costs. For that reason, the majority of the researchers conduct off-line optimization of the cutting parameters. But the off-line optimization is not suitable for newly developed work piece material such as graded materials. To machine such a material and to conduct monitoring of the whole process we developed and applied a new intelligent system for correction of cutting parameters during milling of tool engravings into standard and gradient materials. The introduced system enables on-line optimization of cutting parameters and at the same time excludes the negative impact of human error into production. With the use of visual control and measurements of chip shape, tool wear and cutting forces, the system autonomously performs changes and corrections to both the cutting speed and feed rate. The research presents the introduction of the main problem, search for a suitable solution, assembling the system and experiments to verify the usefulness of the system. A human interface is also developed for a faster reaction time to undesired events. In the conclusion of the research, the main results are presented and suggestions for further work and improvements are given.
Keywords:Intelligent System, Cutting Parameters, Milling of Engravings, Force Control, Visual Control, Chip Shape, Voice Guidance
