“…The surface quality of the workpieces decreases gradually from top to bottom as indicated by Miao et al [31]. The higher the abrasive flow rate, the higher the number of particles involved in the mixing and cutting processes [44]. When the abrasive flow rate is increased, the cutting surface becomes smoother, and low surface roughness is expected due to the greater number of impacts and cutting edges available per unit area.…”

Abrasive waterjet (AWJ) has been widely used for the cutting of hard materials such as rocks. The AWJ cutting of rocks has been well documented in the relevant literature. In these studies, one-pass cutting is employed as the cutting mode. There is no study focusing on the two-pass AWJ cutting of rocks. Therefore, this study aims to fill this gap. Therefore, in the current study, the physicomechanical properties of the rock subjected to cutting are first determined. Following, the workpieces are cut with both one-pass and two-pass cutting modes. In the tests, cutting time is kept constant to compare the performances of cutting modes in terms of the smooth cutting depth and surface roughness. Kerf profiles of the cutting modes are also compared. In the study, significant relationships were not determined between the cutting parameters (abrasive flow rate and standoff distance) and performance outputs for the cutting modes. This may be attributed to the cutting parameters studied in a narrow range. The results indicate that two-pass cutting with higher speeds provides higher smooth depths than one-pass cutting at lower speeds. Two-pass cutting increases smooth depth up to 47%. Results show that surface quality could be improved by two-pass cutting, expanding the smooth zone and reducing the sizes of the striations. The results also show that two-pass cutting improves surface roughness by up to 25%. It is revealed that kerf wall inclination is reduced by two-pass cutting in the upper and lower parts of the kerf. A widened portion caused by the first pass is observed in the final kerf. It can be noted that two-pass cutting cannot provide any improvement in the top kerf width.

“…A recent research study [13] proposes an approach to the complex process of cutting hard rock, analyzing and evaluating the intensity of the disintegration of abrasive materials in the process of cutting AWJ, during the creation of the abrasive jet. Some current processing models on abrasive water jet machines used in the analysis of the behavior of various materials, including rock type are presented in the papers [14][15][16], but in the field of marble cutting by AWJ process research is limited.…”

The appearance of cracks in brittle materials in general and in marble, in particular, is a problem in the hydro-abrasive jet cutting process. In this paper is presented a method to reduce the appearance of cracks when cutting with a hydro-abrasive jet of marble by using statistical analysis. The Taguchi method was used, establishing the main parameters that influence the process. Research design was based on performing experiments by modifying the parameters that influence the process. In this way, it has been shown that the stochastic effects resulting from the marble structure can be reduced. A careful study was made of the behavior of marble under the action of the hydro-abrasive jet, and of the behavior of the whole process in the processing of brittle materials. Results of experiments confirmed the hypothesis that statistical analysis is a procedure that can lead to a decrease in the number of cracks in processing. The measurement was performed with precise instruments and analyzed with recognized software and according to the results obtained, the reduction of the number of cracks is achieved through use of low pressure, a minimum stand-off distance and a small tube diameter. In this way, the paper presents a new and effective tool for optimizing the cutting with a hydro-abrasive jet of marble.
