COMPUTER CONTROLLED 3 AXIS MECHANISM
Get PDFDiplomsko delo vsebuje opis delne realizacije računalniško vodenega triosnega mehanizma. Poudarek diplomskega dela je na izvedbi električnega in programskega dela. Mehanski del, ki trenutno še ni realiziran, bo sestavljen iz linearnih vodil in voden z brezkrtačnimi servo motorji. Električni načrt smo izdelali s programom EPLAN, nato pa smo električno omarico sestavili in med seboj povezali električne komponente. Vodenje mehanizma je izvedeno z uporabo krmilnika vodenja DMC podjetja Galil Motion Control. Programski del smo izdelali s programom LabVIEW, proizvajalca National Instruments. Realizirani programi omogočajo inicializacijo mehanizma, nastavitev PID-parametrov položajnega regulatorja za izbrano os, inkrementalno pomikanje izbrane osi itd. Ti programi so bili nadalje integrirani v kompleksnejšo aplikacijo, ki omogoča vodenje mehanizma z uporabo ukaznih komand v obliki standardne G-kode.This diploma work includes a description of partially realized computer-controlled three-axis mechanism. An emphasis of this work is on electrical and programming part. Mechanical part, which is not yet realized, will be composed of linear positioners and will be driven by brushless servo motors. Electrical plan was created using EPLAN. Based on this plan, we assemble and connect electrical components in the main electrical box. Motion control of mechanism is implemented by using DMC motion controller from Galil Motion Control company. Programing part has been realized using National Instruments LabVIEW. Developed programs enable initialization of mechanism, setting PID parameters of position controller for selected axis, incremental move of selected axis, etc.. These programs have been further integrated into more complex application that allows control of mechanism using standard G-code

Machine Tools for Toolmakers
Get PDFObdelovalni stroji v vseh panogah predstavljajo gonilno silo vsakega podjetja ali celo posameznika. Kot ena od prednosti obdelovalne tehnologije je visoka natančnost izdelkov, kar pomeni tudi zagotavljanje pogojev glede na vrsto stroja, ki ga z ozirom na potrebe dobavimo. Seveda je tukaj vredno omeniti tudi zahteve za posamezen stroj, katere se začnejo že z samimi potrebami po določeni tehnologiji in naprej do izgradnje temeljev ter na koncu postavitev stroja v obrat. Vendar se zahteve tukaj ne končajo, saj tako stroji, kot njihova orodja zahtevajo neprestano kontrolo in menjave za katere je zelo zaželeno, da so ti časi čim krajši ali celo možnost, pri kateri ustavitev stroja za kontrolo ali menjavo sploh ni potrebna.Machine tools in all industries represent the driving force of each company or even an individual. One of the advantages of machine technology is the high precision of products, which also provides the ensuring of conditions in regard of the type of machine, which we supply in regard of the needs. Of course, it is worth mentioning the requirements for each machine, which start already by the technology needs and continue by building foundations and in the end by setting the machine in the plant. However, the requirements do not end here, since machines, and their tools require continual control and replacement of which it is highly desirable that these times are as short as possibleor even offer the possibility that it is not necessary to stop the machinery for control or replacement at all
