| Summary: This thesis investigates the cuttability of granites using abrasive water jet which has been gaining extensive use in diverse areas of industry. 9 different granite samples categorized into three groups in terms of their grain sizes were used. A L16[44*21]Taguchi design was applied in designing experiments. In the experimental design four of the factors were four level and one factor was two level. In the context of the research the granite samples were characterized for their physical, mechanical and mineralogical properties and cuttability of these samples were investigated. It was determined that process parameters affecting the cutting quality were changed depending on the grain size variations of the samples. An analysis evaluation all the samples together determined that grain size, microhardness, specific gravity and abrasiveness as the material properties and abrasive size and traverse speed as the process parameters were effective on the cutting quality. Cutting models were developed using the results obtained through analyses of the cutting results.
