The paper presents optimization of Granite cutting using Taguchi technique in abrasive water jet machining (AWJM). AWJM is commercially utilized for cutting metals such as steel, brass, bronze, aluminium and non-metals such as plastic, wood. However, very limited study is being done using AWJM in rock industry. The present study aimed to investigate cutting performance of AWJM of granite. The experimental design of L9 was used for systematic design of experiment. The process parameters considered were travel speed, stand-off distance (SOD), and water pressure and their effect is measured in terms of Material removal rate. Further, analysis of variance (ANOVA) was used to find most effective cutting parameter.
