Cutting copper sheets using CO2 lasers

Hyperfine Interactions, 1987
In this work various problems concerning cutting copper sheets using CO2 laser are reported. First, all copper thermophysical properties, that regulate the process dynamics, and then the weight of each parameter has been evaluated numerically, even though only approximately.

Experimental investigation into CO2 laser cutting parameters

Journal of Materials Processing Technology, 1996
Abstract The quality of laser cuts is of the utmost importance in laser processing. As laser systems are becoming more demanding, the need for developments in the area of monitoring, diagnosis, regulation and modeling becomes essential to achieve and maintain a high-quality cutting process.

Effects of plasma on CO2 laser cutting quality

Optics and Lasers in Engineering, 1988
Abstract In CO 2 laser cutting, the measurement of plasma size and transmittance is necessary since the plasma appearing on the surface of the workpiece absorbs a fraction of the incident energy and acts as a heat source, enhancing the cutting process.

Corneal cut closure using temperature-controlled CO2 laser soldering system

Lasers in Medical Science, 2015
We aimed to evaluate the effectiveness of temperature-controlled laser soldering for repair of large perforated corneas in a porcine model. Eight Yorkshire pigs aged 6 months underwent 6-mm-deep 180° crescent-shaped trephination of the central corneas.

CO₂Laser Cutting of Calcareous Stones

Materials and Manufacturing Processes, 2004
Abstract Portugal is one of the major European producers of natural stones. In the last decade, transformation of stones has been privileged in most of the companies and the quantity of finished product for exportation increased with a major added value. New technologies and processes have been investigated.

Cutting weeds with a CO₂ laser

Weed Research, 2001
Stems of Chenopodium album. and Sinapis arvensis. and leaves of Lolium perenne. were cut with a CO2 laser or with a pair of scissors. Treatments were carried out on greenhouse‐grown pot plants at three different growth stages and at two heights. Plant dry matter was measured 2 to 5 weeks after treatment.

CO₂ laser cutting: Kerf width variation during cutting

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2005
The kerf width size variation along a laser-cut section lowers the end product quality significantly. In the present study, CO2 laser cutting of mild steel is considered and the influence of laser power and cutting speed variations on the kerf width size is examined.

CO2 laser cutting of advanced high strength steels (AHSS)

Applied Surface Science, 2005
Abstract This article demonstrates the optimum working areas and cutting conditions for the laser cutting of a series of advanced high strength steels (AHSS). The parameters that most influence the cutting of sheet metal have been studied and the results have been divided into two large groups with thickness of more and less than 1 mm. The influence
