Abstract

U suvremenom svijetu laseri pronalaze veliku primjenu u industriji. Zbog svojih svojstava poput beskontaktne obrade i niske potrošnje energije naročito su primjenjivi u postupcima obrade metala poput zavarivanja, rezanja, 3D printanja i graviranja. Mogućnost integracije s drugim tehnologijama, te njihovo jednostavno korištenje pridonose velikom povećanju automatizacije i fleksibilnosti proizvodnog pogona. U ovom radu detaljno je opisana tehnološka primjena lasere s naglaskom na postupak laserskog graviranja koji predstavlja jedan od najzastupljenijih procesa označavanja predmeta. Konvencionalni postupci graviranja zahtijevaju veliki utrošak vremena uz smanjenu kvalitetu izrade. Iz spomenutog razloga u današnje vrijeme uređaji za lasersko graviranje poput galvo glava nalaze veliku primjenu u mnogim granama industrije. Galvo glave biti će razrađene u daljnjem dijelu rada, te će biti navedena mogućnost integracije s ostalim tehnologijama. Operacijski sustavi otvorene arhitekture idealni su za upravljanje CNC strojevima i uređajima za lasersko graviranje. Njihova jednostavna upotreba, te mogućnost primjene na jednostavnim računalima pridodaju im veliku važnost u proizvodne ali i edukacijske svrhe. Kao najpoznatiji sustav ističe se LinuxCNC čija će struktura biti opisana u radu, te će biti naveden primjer njegovog upravljanja CNC strojem za lasersko graviranje. U eksperimentalnom dijelu rada biti će izrađeno konstrukcijsko rješenje ugradnje dostupne galvo glave na 3-osnu glodalicu. Izradit će se modeli konstrukcije i prijedlog njihovog spajanja kako bi se proizveo hibridan stroj s mogućnošću graviranja i glodanja.

Abstract (english)

In the modern world, lasers are finding many applications for industrial purposes. Due to their properties such as contactless machining and low energy consumption, they are particularly applicable in metalworking processes such as welding, cutting, 3D printing and engraving. The possibility of integration with other technologies and their ease of use contribute to a large increase in automation and flexibility of the production plants. This paper describes in detail the technological application of lasers with the main focus on laser engraving which is most widely used process for marking objects. Conventional engravin processes require a lot of time alongside reduced quality of marked objects. For that reason laser engraving devices such as galvo heads are widely used in many industries. Galvo heads or scanners will be elaborated in the further part of this paper and the possibilty of integration with other technologies will also be mentioned. Open architecture operating systems are ideal for controlling CNC machines and laser engraving devices. Their ease of use and the possiblity of application on simple computers make them great for manufacturing and educational purposes. The most famous open architecture system is LinuxCNC, whose structure will be described in this paper, along with an example of its control of a CNC laser engraving machine. In the experimental part of the paper a design solution for the installation of the accessible galvo head on 3-axis milling machine will be developed. Design models and a proposal for their joining will be made in order to produce a hybrid machine with the possibilty of engraving and milling.
