This type of composite is currently in use in aerospace industries. Drilling is the most frequently employed secondary machining owing to the requirements of the fabrication. This composite was subjected to the precipitation heat treatment, hence calling for a study of the precipitation-temperature effect on the machining performance. The composite was fabricated through the powder-metallurgy route. The drilling trials were conducted with a PCD drill of a 5 mm diameter and 118° point angle. The experiments were conducted with different spindle speeds of (500, 1000 and 1500) r/min and feed rates of (10, 15 and 20) mm/min. The thrust force and torque were the performance indicators. The influences of the mass fraction of reinforcement, the precipitation temperature, the feed rate and the spindle speed on the thrust force and torque during drilling were analyzed. It was observed that the drilling performance was influenced significantly by the feed rate followed by the precipitation temperature, the mass fraction and the particle size of reinforcement. The spindle speed did not influence much the machining performance"},{"@xml:lang":"sl","#text":"Namen članka je ugotoviti vpliv temperature izločevalnega žarjenja na zmogljivost vrtanja kompozita Al 2219-SiC. Ta vrsta kompozita se uporablja v letalski industriji. Zaradi potreb pri izdelavi je vrtanje najbolj pogosto uporabljena sekundarna operacija obdelave. Ta kompozit je bil toplotno obdelan z izločevalnim žarjenjem, zato je potrebna študija vpliva temperature izločevalnega žarjenja na zmogljivosti pri obdelavi. Kompozit je bil izdelan po postopkih prašne metalurgije. Preizkusi vrtanja so bili izvršeni s PCD-svedrom premera 5 mm in s konico pod kotom 118°. Preizkusi so bili izvršeni pri različnih hitrostih vrtenja vretena (500, 1000 in 1500) r/min ter hitrostih podajanja (10, 15 in 20) mm/min. Pokazatelja zmogljivosti sta bila potisna sila in navor. Analiziran je bil vpliv masnega deleža delcev za utrjevanje, temperature izločevalnega žarjenja, hitrost podajanja, potisna sila in navor. Opaženo je, da na zmogljivost vrtanja najbolj vpliva hitrost podajanja, nato temperatura izločevalnega žarjenja, masni delež in velikost delcev SiC. Hitrost vrtenja vretena nima bistvenega vpliva na zmogljivost obdelave"}],"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-X54WJM8Q","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-X54WJM8Q"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-X54WJM8Q/3e6eeb5c-c383-4884-9c15-490d8e240b15/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-X54WJM8Q/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-X54WJM8Q"}}}}
