EXPERIMENTAL INVESTIGATION OF SURFACE ROUGHNESS OBTAINED BY ABRASIVE WATER JET MACHINING

Abrasive water jet machining is classified a non-conventional machining procedure. Abrasive water jet machining uses water jet under high pressure as a tool, with added particles of abrasives. The most significant characteristic of the abrasive water jet cutting technology is cold cutting, which does not have a thermic effect on the material. The objective of the experimental investigation is to conduct research of the machining parametres' impact on surface roughness of the machined parts, and derive conclusions referring to the manner in which certain machining parametres affect surface roughness. Experimental investigation was conducted in the way that samples of two different materials were cut on the machine using different machining parametres. Measurement of different surface roughness parametres has been conducted after the cutting.
