Aspects Regarding the Surface Quality of the Laser Engraved Glass

Abstract:

The use of laser engraving equipment for marking on certain products the expiry date, the bar code as well as customizing them, represents an efficient and non-polluting method. This method is very challenging from the technological point of view and with a lot of process variables that demand research. The current paper tackles the quality of the laser engraved glass in CO₂ environment, as a function of the following parameters: the lasers power and the lasers pulse length. Based on the experimental results a quality system is being proposed which relies on the visual examination of the craters, of the top area of the crater and the quantity of excess material surrounding them. The research method used in the current paper is the experiment and the comparative analysis of the experimental results.
