Abstract
Tema ovog diplomskog rada je proučavanje utjecaja dvaju parametara kod laserskog rezanja na kvalitetu rezne površine. Kao materijal ispitivanja odabrana je aluminijeva legura AlMg3 (EN AW 5754) u obliku limene ploče debljine 8 mm. Aluminijeve legure spadaju u teško rezljive materijale zbog svoje visoke reflektivnosti i toplinske provodnosti. Uzorci na kojima su provedena ispitna mjerenja izrezani su pomoću fiber lasera snage 10 kW. Prvi dio ovog rada daje pregled razvoja lasera kao tehnologije te osnovne pojmove i načela rada lasera. Nakon toga definirani su osnovni pojmovi i mehanizmi vezani uz tehnologiju laserskog rezanja. Drugi dio ovog rada je eksperimentalan, a u njemu su definirani svi parametri izvedenog pokusa te je opisan postupak kod pripreme uzoraka i provođenja mjerenja. Nakon toga, izmjereni podaci su obrađeni i prikazani te je analiziran utjecaj brzine rezanja i položaja žarišne točke na kvalitetu reza.
Abstract (english)
The goal of this master's thesis is to study the influence of two laser cutting parameters on cut surfface quality. AlMg3 (EN AW 5754) aluminum alloy is chosen as a sample material in form of 8 mm thick sheet. Aluminum alloys represent materials group that are hard to cut becaouse of their high reflectivity and heat conductivity. 10 kW fiber laser cutting machine is used tu cut the samples. The history of laser technology development along with key terms and principles of laser technology are described in first part of this thesis. Then, the terms and mechanisams of laser cutting technology are defined. The second, experimental, part of this thesis is where parameters of conducted experiment are defined. The details of sample preparation and conducted mesurings are described. After that the dana show along with analysis of coutting speed and focal point position influence on laser cut surfface quality.
