Original abstract

Experimental study of the surface quality produced by abrasive waterjet (AWJ) on metallic materials has been performed. The surface roughness/waviness was quantitatively evaluated by using the contactless optical measurement. In order to characterize the cut surface qualities, a single-parameter criterion has been proposed. Based on root mean square (RMS) roughness evaluation of the worst cut surface zone, the dimensionless statistical parameter C can be calculated as a basic quantity for AWJ surface cut characterization. As it was approved, besides its dependency on depth of AWJ trace, the value of C-parameter for the specific material is noticeably related also to the traverse speed of the cutting head. Such a relationship can be potentially used for adjusting the cutting speed of the machining process

Czech abstract

Byla provedena experimentální studie kvality povrchu kovových materiálů vytvořených vodním svazkem. Drsnost/ vlnitost povrchů byla kvantitativně určena pomocí bezkontaktního optického měření. K popisu kvality těchto povrchů bylo navrženo jednoparametrické kritérium. Na základě rms drsnosti nejméně kvalitní zóny povrchu byl vypočten bezrozměrný statistický parametr C jako základní veličina charakterizující daný povrch. Bylo ukázáno, že hodnota parametru C je pro daný materiál svázána s rychlostí řezné hlavy. Tento vztah lze potenciálně užít k nastavení řezné rychlosti obráběcího procesu.
