Abstract To address the challenges of poor surface quality and high energy consumption in marble cutting, this study introduces an auxiliary abrasive jet cutting technology enhanced by the use of polyacrylamide (PAM) as a drag-reducing additive. The effects of feed rate (50–300 mm/min), polymer concentration (0–0.5 g/L), and nozzle spacing (4–12 mm) on kerf width and surface roughness are systematically investigated through an orthogonal experimental design. Results reveal that feed rate emerges as the most significant factor (p < 0.01), followed by PAM concentration and nozzle spacing. The optimal set of parameters, comprising a 200 mm/min feed More >
