Abstract

Rock processing is crucial across industries like tunneling, construction, mining, aerospace, and oil exploration, driven by rising energy demands and the need for high-strength materials. Conventional methods face challenges with tool wear and complexity. Laser-based processing offers promise but confronts issues like rock anisotropy and parameter irregularities. This study explores laser scanning of Jalore Pink Granite and Basalt Chip Stone using a 100 W CW CO2 laser. The impact of laser beam scans on modified specific energy and rate of penetration is analyzed. Optical microscopy reveals distinct interaction mechanisms: rod-like patterns for Jalore granite and edge melting with one-side accumulation for basalt. Results highlight the efficacy of beam scans in laser rock processing, advancing understanding of material removal dynamics. [ABSTRACT FROM AUTHOR]
