Awj Cutting

The cutting performance in abrasive waterjet (AWJ) multipass cutting with and without controlled nozzle oscillation is presented based on an experimental investigation cutting an 87% alumina ceramic. The cutting capacity in terms of the depth of cut and the kerf geometrical features is analyzed with respect to the process variables. It is found that multipass cutting is a viable means to increase the cutting performance and application domain of this technology, while a further increase in the cutting performance can be made by using a controlled nozzle oscillation technique.
