Abstract:V teoretičnem delu diplomskega dela predstavljamo hitro izdelavo prototipov in slojevite dodajalne tehnologije, med katere spada tudi selektivno lasersko sintranje. Nadalje predstavljamo trikoordinatno merilno tehniko, zgradbo koordinatne merilne naprave, vrste koordinatnih merilnikov, lastnosti in princip merjenja s koordinatno merilno napravo in potek meritve na napravi. Empirični del diplomskega dela temelji na merjenju merjenca, izdelanega s postopkom selektivnega laserskega sintranja, na trikoordinatni merilni napravi. V začetku empiričnega dela je predstavljeno off-line programiranje, pri čemer smo se podrobneje posvetili programski opremi, izbiri tipala ter merilni strategiji. Nadalje opisujemo, kako je potekala meritev našega merjenca na trikoordinatni merilni napravi. Rezultati empiričnega dela kažejo, da je izbran izdelek izdelan dokaj natančno, saj je izven tolerančnih mej le nekaj mer. Ugotovili smo, da je natančnost izdelave odvisna od homogenosti temperature v izdelovalni komori ter od postavitve samega izdelka v komori.

Title:TESTING THE ABILITY OF LASER SINTERING PROCESS WITH THE USE OF COORDINATE MEASURING TECHNIQUE
Abstract:In the theoretical part of the undergraduate thesis we present the fast production of prototypes and layered additive technology, which includes selective laser sintering. Furthermore, we present three-coordinate measurement technique, the structure of coordinate measuring machine, the types of coordinate measuring devices, measuring principle and characteristics of coordinate measuring device and the measurement process on the device. The empirical part of the undergraduate thesis is based on the object measurement produced by the selective laser sintering on the three-coordinate measuring device. At the start of the empirical work the off-line programming is presented, where we focused on the software, sensor selection and measurement strategy. Furthermore, we describe how our object measurement took place on the three-coordinate measuring device. The results of empirical work show that the selected product is made with reasonable accuracy, as there are only few dimensions outside the tolerance limits. We found that the precision manufacturing depends on the temperature homogeneity and the product placement in the forming chamber.
Keywords:layered manufacturing, additive processes, selective laser sintering, rapid prototype production, coordinate measuring technique, off-line programming, probe, measuring strategy.
