Abstract
Tehnološki problemi, s katerimi se srečujemo na področju uporabe strojev za lasersko odrezovanje, so posledica nezadostnega poznavanja laserske tehnike in pomanjkanja dovolj zanesljivih podatkov iz prakse in poznavanja parametrov, ki vplivajo na sam postopek odrezovanja. Pomemben parameter, ki ga moramo določiti in vključiti v programsko opremo številskega krmiljenja, je rezalna hitrost. Različni avtorji analizirajo postopek lasreskega odrezovanja in podajajo matematične modele, pri katerih je lasersko odrezovanje modelirano z rezalno hitrostjo, kot ključnim parametrom odrezovanja. Stevilčno vrednost rezalne hitrosti lahko določimo iz priporočil proizvajalca, z določenimi izkušnjami ali z uporabo enačb iz literature. V tem prispevku so predstavljene nekatere možnosti za določitev parametrov laserskega odrezovanja in rezalne hitrosti, na podlagi stopnje odrezovanja, ločilne energije in rabe specifične moči.

Abstract:
The technological problems faced in the field of the application of laser-cutting machines lie in insufficient knowledge of the laser technique and the absence of both sufficiently reliable practical data and knowledge about the parameters affecting the work process itself. A significant parameter that is necessary to determine and to enter in an NC-program is the cutting speed. Various authors analyze the laser-cutting process and give mathematical models where laser cutting is modeled by using the cutting speed as the key cutting parameter. The numerical value of the cutting speed can be determined from the recommendations of manufacturers, a particular experience or with the aid of equations from the literature. This paper presents some possibilities for determining laser-cutting data and cutting speed based on cutting rate, severance energy, and the specific power consumption.
