Abstract

The current thesis describes the use of abrasive water jet as an etching tool in Branco de Cachoeiro de Itapemirim Marble plate and in float glass plate. Etching process performance variations are introduced as well as different kerf geometries obtained with variation of many processes parameters. The results of the etching in several samples have been photographed and scanned. Furthermore the results of the etching of a complex drawing in marble and glass is shown. Finally conclusions and discussions over the achieved results are described. (AU)
