Experimental Investigation on Surface Topography of the Natural Ceramics in Abrasive Water Jet Cutting and Its Optimization Validation by Formulated Model
In the recent past, many researchers have examined the striation and taper angle emergence on the machined surface of several kinds of materials, machined through Abrasive Water Jet (AWJ). There are a few investigations that focused on the undesirable striation and taper angle formation on the machined surface of natural ceramics. In this work, machining of three different natural ceramic materials such as granite, white marble, and gray marble, is carried out through the AWJ process. The influence of the machining process parameters on zone thickness, kerf striation angle and kerf taper angle were investigated. In order to understand the surface morphology, the machined surface is divided into three different zones such as smooth (Zone 1, 0°–5°), transition (Zone 2, 5°–10°), and rough (Zone 3, >10°) respectively. The entire result shows good agreement between the formulated model (using Buckingham’s π-theorem) and Response Surface Methodology (RSM).
