| Abstract | |
This study presents a classification of the various technologies used to cut dimension stones and attempts to place technologies of water jet cutting and abrasive water jet in this classification. The intention is to establish a relationship between the technological characteristics as well as the mineral composition of the stones that have been tested and the maximum depth of cut obtained with different traverse rates in the abrasive water jet cutting process. For this purpose, several dimension stones were selected, such as Prata Interlagos granite, Vermelho Capão Bonito granite and Preto Piracaia granite, as well as Branco Campos do Jordão marble and a \"non-dimension\" stone, the diabase. Several tests were conducted to determine their characteristics and composition. To determine the maximum depth of cut, these rocks were tested with the abrasive water jet cutting equipment available at the Rock Mechanics Laboratory in the Department of Mines and Petroleum Engineering at EPUSP.
