Abstract
Laser stimuliranom emisijom stvara uski snop elekromagnetnog zračenja. Glavna prednost obrade materijala laserom je lakša obrada teško dostupnih dijelova bez mehaničkog kontakta. Česta primjena lasera je u graviranju pri čemu promjena parametara rada rezultira različitim svojstvima gravure, npr. hrapavosti površine. Hipoteza ovog rada jest da brzina, snaga lasera i frekvencija pulsa imaju utjecaj na hrapavost površine nakon obrade. MATERIJALI I METODE: U istraživanju je, korištenjem laserskog uređaja Baublys CF20 IP/NC30, na 3 pločice čelika X5CrNi 18-10 i 3 pločice mesinga CW508L ugravirano 15 kvadrata dimenzija 15x15 mm. Mjerenje hrapavosti izvršeno je pertometrom Surftest SJ310, a uz pomoć programa Design Expert napravljena je analiza odzivne površine u obliku centralno kompozitnog plana pokusa za parametar hrapavosti Rz. Napravljen je MannWhitneyev test za provjeru postojanja razlika između medijana parametara graviranja za čelik i mesing korištenih za postizanje iste hrapavosti. Odabrana razina značajnosti u ovom radu je α=0,05.
Abstract (english)
Laser projects a narrow beam of light by stimulated emission. The main advantage of using lasers in industry is lack of contact and possibility to process hardly reachable parts. Laser engraving enables creating patterns with different proporties, such as surface roughness by changing process parameters. Hypothesis of this study is that the speed and power of laser and frequency of pulse affect engraved surface roughness. MATERIALS AND METHODS: Laser device Baublys CF20 IP/NC30 was used to engrave 15 squares with dimensions 15 x 15 mm on each of the 3 stainless steel X5CrNi 1810 tiles and 3 brass CW508L tiles. Surface roughness was measured using perthometer Surftest SJ-310 and Desing Expert software was used for response surface methodology. Rz parameter was analyzed in central-composite design. Mann-Whitney test was used to determine whether there was a difference between engraving parameters used for two materials to achieve the same surface roughness. Level of significance used in this study was α=0,05.
