Parametric investigation of CO2 laser cutting of 2024-T3 alloy

A new method for the prediction of laser cut surface topography

“…The mechanism of cutting by means of a laser beam as a mechanically flexible cutting tool with thermal effects and many other factors entering into the mechanism of material disintegration is very problematic [1], [2], [3]. Thanks to experimentally performed measurements a development of numerical values of the surface (profile) roughness parameter Ra could be observed and measured.…”

“…Currently, the LBC technology is still subject of concentrated research, as it is evident by a number of various publications. Many of experimental studies were designed to understand the factors affecting the performance of the cutting process [1], [2], [3]. The laser cutting technology and the accompanying phenomena occurring in the process of laser beam cutting or laser beam welding have been and still are the subject of many research activities with a view to optimizing technology parameters influencing cut or weld quality [4], [5], [6], [7].…”

CO2 laser cutting of natural granite

“…Taguchi methods have been also used by Dubey and Yadava to optimize the process of laser cutting of nickel-based superalloys. Riveiro et al [18] proposed a factorial analysis to identify the main processing parameters during pulsed laser cutting of Al2024-T3 alloy. Best quality results were identified under the combination of high laser power, high pulse frequencies, and moderate duty cycles.…”

“…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.…”

CO2 laser cutting of phenolic resin boards

“…Belforte (2010) estimated that more than 75,000 sheet metal laser cutting machines have been installed worldwide since its initial application in 1970, most of them equipped with a CO 2 laser. Laser cutting has been successfully utilized to process very different materials: from mild steels (Ivarson et al, 1994), high strength steels (Thomas et al, 2011), titanium alloys (Yilbas, 1988), aluminium alloys such as AA5083 (Stournaras et al, 2009), or AA2024-T3 (Riveiro et al, 2010), to thermoplastic polymers such as polyethylene (PE), polypropylene (PP), or polycarbonate (PC) (Caiazzo et al, 2005) or polymethyl methacrylate (PMMA) (Davim et al, 2008). Also different types of composites such as glass fibre reinforced plastic composites (Cenna and Mathew, 1997) or flax fibers reinforced polypropylene (PP) (Pou et al, 2001), ceramics as mullite alumina (Quintero et al, 2004), or even natural rocks such as slate (Boutinguiza et al, 2002) have been cut by CO 2 lasers.…”
