Comparison of the of precision manufacturing of holes during laser cutting of materials on various types of CNC cutting centers
 Petruška, David ; Dostál, Jan (referee) ; Mrňa, Libor (advisor)
The thesis compares the precision of 90x90 mm laser cutouts with circular and quadrangular holes which are divided into two CNC cutting centers with different axle drive types. On both machines, the samples are cut through both oxidative and fusion cutting. Measurement was carried out using a sliding scale and for a more detailed and accurate analysis on a 3D coordinate measuring machine with a touch system. The results of the measurements showed that the more suitable cutting method for sheet metal cutting CSN 11321 DC01 is melting. Deviations of the nominal dimensions are comparable when cutting on both machines, so the choice of the machine for production speeds, operating and acquisition costs depends on the serial production of these burners.
