Abrasive Waterjet Cutting Surfaces of Ceramics – An Experimental Investigation

Abrasive waterjet cutting has been proven to be an effective technology for processing variety of engineering materials. It is an emerging technology and has various distinct advantages over the other non-traditional cutting technologies. This paper assesses the influence of process parameters on surface roughness (Ra) which is an important cutting performance measure in abrasive waterjet cutting of ceramics. Experiments were conducted in varying water pressure, nozzle traverse speed, abrasive mass flow rate and standoff distance for cutting ceramics using abrasive waterjet cutting process. The effects of these parameters on surface roughness have been studied based on the experimental results and useful recommendations have been given in order to select the suitable process parameters in abrasive waterjet cutting of ceramics.
