Other input parameters of forming system (friction conditions, machine settings, temperature, etc.) also scatter considerably during production. Improvement of production processes has always been an important goal in metal forming industry. The aim is to develop cost effective and stabile forming processes where the number of non-conforming products (scrap) is reduced to the minimum. In the first part of the paper an approach is described which enables the user to predict how the scatter of input parameters would influence the final properties of the products. In the second part of the paper the developed approach is used for optimization of forming process with respect to uncontrollable scatter of input parameters with the aim of minimizing scrap ratio. Optimization is basedon the use of numerical simulations, response surface methodology and stochastic optimization. It can be performed in the early stage of the production process development cycle. The presented approach was successfully applied in industrial environment during development of technology for forming of various work pieces</dc:description><dc:description xml:lang="sl">Lastnosti vhodnega materiala (pločevine, palic itd.), ki se uporablja v preoblikovalnih postopkih, so spremenljive. Tudi ostali vhodni parametri preoblikovalnega sistema (torni pogoji, nastavitve stroja, temperatura itd.) med proizvodnjo znatno nihajo. Izboljševanje proizvodnih postopkov je bil vedno pomemben cilj v kovinsko-predelovalni industriji. Cilj je razviti stroškovno učinkovite in stabilne preoblikovalne postopke, kjer je izmet zmanjšan na najmanjšo vrednost. V prvem delu prispevka je opisan pristop, ki uporabniku omogoča napovedati, kako bo raztros vhodnih spremenljivk vplival nakončne lastnosti izdelkov. V drugem delu prispevka je razviti pristop uporabljen za optimizacijo preoblikovalnega postopka z namenom zmanjšanja izmeta, pri čemer je upoštevan vpliv nenadzorovanega raztrosa vhodnih spremenljivk. Optimizacijski postopek sloni na uporabi numeričnih simulacij, metode odzivne povrsine in stohastične optimizacije. Uporabljen je lahko v zgodnji fazi tehnološke priprave proizvodnje. Predstavljen pristop je bil uspešno uporabljen pri razvoju preoblikovalnih tehnologij za različne obdelovance v industrijskem okolju</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-C3DAN82U"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-C3DAN82U" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-C3DAN82U/246d2cc0-7969-4742-a812-6271ce7b800a/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za strojništvo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-C3DAN82U/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-C3DAN82U" /></ore:Aggregation></rdf:RDF>
