ince we clearly see the formation of an uniform hole provided with a well traced contour and quite clean, which allows us to conclude that the power 30% equals exactly to 7.5 W and 2 s time exposure are identified as optimal parameters for drilling the organic glass. The great powers and the highest drilling time are not recommended because together carried the plastic deformation of the material in the vicinity of the hole.

5. Conclusion

Works done in this project have as principal aim the exploitation of laser technology to perform micro-holes glasses lenses to facilitate mounting of the arms in the holes at the edges for the best solutions to our visual needs. The quality of our vision and our well being are intimately tied to visual quality lenses and frames, adapt precisely to the shape of the face gives us total comfort. We used the marking system CO2 laser available at Advanced Technology Development Center (CDTA) Baba Hassen (Algiers), for the drilling of three types of glass. The select laser parameters were limited in the intention to protecting the marking system and avoid damage or destroy it, since it was only suitable for drilling. Generally, the laser glass drilling requires special accessories designed for micro machining of the glass. It was found that ordinary glass blades crack at the first contact with the laser regardless of the power and drilling time applied, thus notices the same thing for the mineral glass. The select of laser parameters was limited in the intention to protecting the marking system and avoids damage or destroy it, since it was only suitable for drilling. Generally, the laser glass drilling requires special accessories designed for micro machining of the glass. It was found that ordinary glass blades crack at the first contact with the laser regardless of the power and drilling time applied, thus notices the same thing for the mineral glass. We are interest only to the drilling of organic glass; it was found that the diameter of drilled holes is proportional to the powers and the drilling time. Based on observations and interpretations, we concluded that for organic glass optimum parameters are 30% of power and 2 s is the best time and give the most favorable choices, against the increase in power and time exposure widen the holes and create a distortion in the vicinity of these bores (influence of power and the drilling time on the quality of the drilled holes) due to the plastic flow of the material, the latter is generated by increasing the heat imported by the laser beam.
