A study on the abrasive water jet cutting for granite

This paper presents the investigation of an effective abrasive water jet (AWJ) method for granite cutting. Suitable conditions were explored by considering many process parameters, such as water pressure, jet diameter, nozzle traversing speed, abrasives and so on. Meanwhile, the accoustic emission (AE) signals of the process were detected by using an AE sensor during the experiments. Different patterns of signals were discussed in relation to the process behaviour. Based on the analyzed results, a guideline for cutting granite is provided for improving surface quality and productivity.
