A study on abrasive waterjet multi-stage machining of ceramics

Abrasive waterjet (AWJ) milling is a promising technique for machining hard materials, but it is also complex to implement. In modern production scenarios, multi-stage machining is a matter of course to improve both performance and quality. Since AWJ milling is still developing, there is little knowledge about a corresponding process design. In this study, an innovative approach for AWJ multi-stage machining of a ceramic specimen is experimentally investigated. To produce either a high removal rate or a fine surface, different parameters of abrasive grit interacting with the workpiece surface and its potential for surface integrity are analyzed for future applications.
