WEDM is also a modification of electrical discharge machining (EDM) and it has been widely used for a long time for cutting punches and dies, shaped pockets and other machine parts on conductive work materials. The surface roughness of a machined surface mainly depends on the feed rate, the current and pulse duration in the WEDM machining process. It also depends on the optimum selection of WEDM parameters. The present study focused on the multiple regression modeling and predicting the surface roughness of the Dievar hot-work tool steel during the WEDM process. Mathematical relationships between the surface roughness and WEDM cutting parameters (feed rate, current and pulse on time) have been investigated. The results show that the multiple regression analysis is a successful method for developing a mathematical model to predict the surface roughness"},{"@xml:lang":"sl","#text":"Obdelovanje z žično erozijo (WEDM) je poseben toplotni postopek, ki zagotavlja natančno rezanje in obdelovanje mehanskih delov z različno trdoto in zapleteno obliko. WEDM je modificirana elektroerozija (EDM) in se že dolgo uporablja za rezanje prebijal in orodij, oblikovanih žepov in drugih strojnih delov na prevodnem obdelovancu. Hrapavost površine je predvsem odvisna od hitrosti odvzema, toka in trajanja pulza pri WEDM-procesu obdelave. Odvisna je tudi od optimalne izbire parametrov pri WEDM. Ta študija je osredinjena na večkratno regresijsko modeliranje in napovedovanje hrapavosti površine orodnega jekla za delo v vročem Dievar pri obdelavi z WEDM. Preiskovana je bila matematična odvisnost med hrapavostjo površine in parametri rezanja WEDM (hitrost podajanja, tok in časovni impulzi). Rezultati kažejo, da je večkratna regresijska analiza uspešna metoda za razvoj matematičnega modela za napovedovanje hrapavosti površine"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-8U38QJUD","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-8U38QJUD"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-8U38QJUD/4328662c-eafa-4ac0-8550-9cfbcb0bccd6/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Inštitut za kovinske materiale in tehnologije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-8U38QJUD/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-8U38QJUD"}}}}
