Slate is a natural stone which has the characteristic that shows a well-developed defoliation plane, allowing to easily split it in plates parallel to that plane which are particularly used as tiles for roof building. At present, the manufacturing of slate is mostly manual, being noisy, powdery and unsafe for the worker.

CO2 laser cutting of stained glass
The International Journal of Advanced Manufacturing Technology, 1996This paper covers the CO2 laser cutting of stained glass using a Ferranti MF400 CNC laser cutting machine. The report examines the various laser cutting parameters required to generate a cut surface in glass which will require minimal post-treatment to be carried out, and also investigates the degree of geometrical intricacy that can be attempted ...

CO2 laser cutting of natural granite
Optics & Laser Technology, 2016Abstract Commercial black granite boards (trade name: “Zimbabwe black granite”) 10 mm thick, were successfully cut by a 3.5 kW CO2 laser source. Cutting quality, in terms of kerf width and roughness of the cut wall, was assessed by means of statistically planned experiments.

CO2 laser cutting of flexible glass substrates
ICALEO 2011: 30th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2011We investigated CO2 laser cutting of flexible glass substrates using water cooling jets. We found thelaser beam length and width only slightly affected the laser cutting speed. We attribute the weak dependence to the rapid thermal homogenizing process in flexible glass. This paper discusses the optimallaser cutting process window.

CO2 laser cutting of phenolic resin boards
Journal of Materials Processing Technology, 2011Abstract CO2 laser cutting process of phenolic resin boards has been assessed using a design of experiments (DOE) based methodology. The feasibility and quality of this process is analyzed and compared with the results from laser cutting of particleboard panels.

Cutting of slate tiles by CO2 laser
ICALEO 2000: Proceedings of the Laser Materials Processing Conference, 2000Slate is a natural stone which has the characteristic that shows a well developed defoliation plane, allowing to easily split it in plates parallel to that plane which are particularly used as tiles for roof building. At present, the manufacturing of slate is mostly manual, being noisy, powdery and unsafe for the worker. Thus, there is a

Cutting and welding using a CO2 laser
Optics & Laser Technology, 1972Abstract Of all the types of lasers now available, the CO 2 laser is particularly suitable for materials working. It has a very high efficiency (15–20%) and a high out-put power (up to several kW). When the laser light is focused by means of a lens or a mirror, a c.w. power density of more than 10 9 W cm -2 can be attained.

New aspects of cutting with CO2-lasers
ICALEO '91: Proceedings of the Laser Materials Processing Symposium, 1991Experimental investigations reveal that higher cutting velocities can be obtained by using circularly polarized laser light instead of using laser light linearly polarized parallel to the cutting direction. This is an unexpected effect because of the better absorption of the parallel polarization at the workpiece in cutting direction.

CO2 laser cut quality of 4130 steel
International Journal of Machine Tools and Manufacture, 2003Samples of 4130 steel were cut on a CO2 laser cutting system and the combined effects of power and feed rate on kerf width, surface roughness, striation frequency and the size of heat affected zone (HAZ) have been studied. Regression analysis was used to develop models that describe the effect of the independent process parameters on laser cut quality.

Electrothermal Cutting Processes Using a CO2 Laser
IEEE Transactions on Industry Applications, 1972The application of lasers to industrial electrothermal processes is discussed together with the factors affecting the choice of laser. The use of gas jet assistance in cutting applications is described, and the influence of gas jet assistance on the cutting rate and cut quality for metals and nonmetals is shown.
