A laser beam machining (LBM) database for the cutting of ceramic tile

Laser Machining and Laser-Assisted Machining of Ceramics

“…In the database produced by Black et al (29), it was found that thicker tiles were cut successfully by the multipass method without degradation of cut quality. The objective of multipass cutting was to reduce thermal overload by the use of less input energy per unit length.…”

Laser beam machining—A review

“…Laser cutting of thick (1-10 mm) alumina ceramic substrates through controlled fracture using two synchronized laser beams, focused Nd:YAG (for scribing the groove crack) and defocused CO 2 (to induce thermal stresses) show that surface finish obtained at 60 W laser power (for both Nd:YAG and CO 2 ) and 1 mm/s cutting speed was much better than conventional laser cutting [84]. The surface roughness of thick ceramic tiles during CO 2 laser cutting is mainly affected by ratio of power to cutting speed, material composition and thickness, gas type and its pressure [40,41]. Use of nitrogen assist gas and lesser power intensities reduce the surface roughness [74].…”

“…Cutting of commercially available ceramic tiles using diamond-saw, hydrodynamic or USM are time consuming and expensive in processing of particular shape. LBM can cut intricate shapes and thick sections in these tiles [40][41][42].…”

CO2 laser cutting of natural granite

“…An alternative to increase the assist gas performance is the utilization of off-axial supersonic nozzles. This technique has been successfully used for cutting metals such as stainless and mild steel [24] or 2024-T3 aluminium alloy [18]; ceramics such as tiles [25] or mullite-alumina [26]; polymers such as polyethylene, polypropylene, polycarbonate [27] or polymethyl methacrylate [28], or wood [29]; however, it has not been widely explored for cutting granite stones.…”
