Abstract: Marble material is characterised by its high fragility and heterogeneousness, which directly depend on two main aspects: the origin and nature. Marble manufacturing for commercial and industrial uses involves many processes, such as the machining process, which requires detailed knowledge of marble characteristics and features. One of these important characteristics is the stone cutter point, an essential input to identify the marble machining parameters. In this study, an examination was achieved to optimise the marble drilling industry quality process. The main objective is to achieve high-quality marble drilling without fracturing. White Carrara marble was used to examine its drilling process. The utilised drilling method was the Abrasive-Water-Jet (AWJ); unlike conventional drilling methods, such as rotating abrasive can achieve better drilling quality. The performance and quality of the AWJ process depend on several considerations, including jet pressure, the nozzle Traverse-Speed (TS), hole diameter, Stand-Off-Distance (SOD) as well as Abrasive-Flow-Rate (AFR). All these parameters were studied and modelled, besides the most common defect types. The studied defect types involve hole location error and circularity, hole location error, surface roughness, and hole cylindricity. Variance analysis of artificial neural networks, as well as linear regression were utilised for modelling these types of defects. Accordingly, marble stone cutters can be effectively determined and utilised in configuring marble machining parameters, hence optimising its manufacturing process.
