The processing laser beam in our new system is deflected in one direction by a hexagonal mirror prism rotating at a constant angular velocity.Each laser pulse produces a dot-shaped mark (a "laser dot") on the surface of the workpiece. By scanning the beam along a straight line we achieve a linear, uniformly distributed pattern of laser dots. The linear translation stage below the beam deflector moves the workpiece in a direction perpendicular to the line. The result is a two-dimensional raster (matrix) pattern consisting of an arbitrary number of lines with up to 200 laser dots per line. We have developed a microprocessor-based marking-system controller that coordinates the operation of the laser source, the laser-beam deflector and the linear translator in such a way that it is possible to produce arbitrary dotted raster patterns. The system was tested by marking one- and two- dimensional patterns. The tests showed that the system is suitable for the rapid production of simple dotted patterns on workpieces that are moving on production belts</dc:description><dc:description xml:lang="sl">Prispevek predstavlja razvoj optomehatronskega sistema, ki omogoča izdelavo rastrskih vzorcev pri laserskem označevanju. Sistem deluje tako, da v eni osi odklanjamo obdelovalni laserski žarek s pomočjo poligonskega zrcala v obliki šesterokotne prizme, ki se vrti s konstantno kotno hitrostjo. Vsak laserski blisk povzroči na površini obdelovanca označbo v obliki točke. Z odklanjanjem žarka dosežemo, da so točkaste označbe razvrščene enakomerno v ravni črti - vrstici. Pomična miza, ki je pod odklanjalom, omogoča pomik obdelovanca pravokotno na vrstico. Rezultat obojega je dvorazsežna rastrska (matrična) označba z do dvesto točkami v smeri odklanjanja žarka. Razvili smo mikroprocesorski krmilnik sistema, ki omogoča usklajeno delovanje laserja, odklanjala ter pomične mize in s tem izdelavo točkovne oznake na obdelovancu na poljubnem mestu rastra. Sistem je bil preizkušen z označevanjem eno- in dvodimenzionalnih rastrskih označb. Testi so pokazali, da je rastrsko vodenje zarka izvedljivo in zelo primerno za hitro označevanje preprostih označb na obdelovance, ki so že vključeni v nek proces obdelave na tekočem traku</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-DAYENF75"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-DAYENF75" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-DAYENF75/a7983903-8b5b-4f40-b774-4475ae38d373/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-DAYENF75/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-DAYENF75" /></ore:Aggregation></rdf:RDF>
