The objective of the study is to determine the effect of milling parameters and end mill geometry on machining safety, defined as the minimum probability of chip self-ignition. The assessment of safety and effectiveness in the milling of magnesium must include analysis of chip fractions formed during the milling process. The paper presents the state of the art of magnesium alloy machinability in terms of chip formation (chip fragmentation). Furthermore, the paper investigates the correlation between the quantity of distinguished chip fractions and variations in the parameters vc and fz as well as in the rake angle yo. In addition, the results of the dimensions of individual chip fractions are reported. The study was conducted on AZ91HP magnesium cast alloy, and the milling process was performed using carbide tools with varying rake angles (yo = 5% and yo = 30%). It has been found that chip fragmentation increases by increasing the above parameters, i.e. the feed rate fz and the cutting speed vc. The observed chip fragmentation (the quantity of chip fractions) is lower at the tool rake angle yo = 30%. Finally, technological recommendations are formulated based on the quantity of chip fractions generated at particular settings. The results do not unequivocally demonstrate that chip dimensions increase or decrease by increasing the operational parameters of the milling process. In terms of their application, it is vital that machining processes be simultaneously effective and safe"},{"@xml:lang":"sl","#text":"Glavni cilj eksperimentov je bila določitev varnih, a učinkovitih tehnoloških parametrov procesa istosmernega rezkanja. Članek obravnava korelacijo med količino različnih frakcij odrezkov ter parametri vc, fz in cepilni kot yo. Poznavanje odvisnosti med omenjenimi parametri je izjemnega pomena za najboljšo uspešnost in varnost obdelovalnega procesa. Sekundarni cilj študije je analiza frakcij odrezkov, ki se oblikujejo pri rezkanju magnezijevih zlitin. Fragmentacija odrezkov ni zaželena, saj lahko privede do nenadzorovanega vžiga manjših frakcij odrezkov med rezkanjem, kakor tudi do onesnaženja kinematičnih parov in delovnega prostora rezkalnega stroja. Standard ISO 3685:1993 priporoča razvoj sistema za razvrščanje odrezkov, ki bo uporaben za vsak realen proces rezkanja. Bistvo problema, ki je razdelan v tem članku, je določitev takšnih parametrov rezkanja, ki prinašajo minimalno količino prašne frakcije"}],"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-L99S8F2T","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-L99S8F2T"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-L99S8F2T/d6937f32-84bf-4c49-bceb-22ec162cfc06/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":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-L99S8F2T/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-L99S8F2T"}}}}
