Analisys of the material for laser cutting
Tonkovič, Miroslav ; Kolář, Ladislav (referee) ; Osička, Karel (advisor)
This thesis deals with laser cutting of metal sheets from selected steel producers. The basics of laser technologies, especially in industrial use, are described in the introductory part. There the material requirements are described from the point of view of laser cutting. The comparison of materials from different steel producers is made from different angles in the practical part. The conclusion is dedicated to the evaluation of achieved results.

Techno-economical comparison of the fusing and flame method of laser cutting of steel sheets with a solid-state laser
Vojteková, Lucia ; Hála, Michal (referee) ; Mrňa, Libor (advisor)
The aim of diploma thesis is a comparison of flame and fusion laser cutting of thin metal sheets for ACO Industries k. s. company, where the experimental part was also realized. After consultation with company, the thesis was extended by data samples, which were cut by compressed air for comparison with other two gases. The optimization design of cutting parameters was created by Taguchi method. Afterwards the surface roughness of samples was measured. Based on Ra and Rz5 parameters, the samples were classified to classes based on their accuracy according to ISO 9013 standard. According to results the fusion method of laser cutting is more suitable method, especially for its good quality of cutting edge, which is not affected by the oxidic layer. Fusion method uses cutting speed two times higher than the flame method, which leads to decrease of time and financial consumption of the process despite of its higher hourly rate. In case of laser cutting of material by compressed air the quality of cut is insufficient in comparison with fusion or flame cutting method.
