“…Laser methods of PMMA treatment are considered in numerous articles from various points of view: simulations, experiments with different types of laser devices, industrial applications, material processing for optical components, cutting and shaping of panels, tropheys, fiber applications, etc. [3][4][5][6][7][8][9][10][19][20][21][22][23][24][25][26][27]. The part of the theory used in these descriptions is applicable also for the other transparent materials, composites, glassy and plastic materials.…”

“…Concerning the broad area of its applications, the vast of reference data can be found about the laser methods for PMMA shaping [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The optimization of laser systems working regimes, including the investigated of large variety of laser pulses going down to femtosecond duration were also performed, both theoretically and experimentally.…”

Due to its excellent mechanical, chemical and optical properties, also on fatigue, polymethilmetacrylate (PMMA) is widely used for many purposes. PMMA has a reputation as a material that cannot be machined well, but, its elasticity and toughness enable its shaping by the deformation processes. Laser drilling and cutting are also available techniques for PMMA sheets shaping, used when both mechanical and optical PMMA properties must be preserved. In this work, the influence of CO 2 laser cutting/drilling on transparent and coloured PMMA surfaces is investigated, as well as by the other laser systems. The cut surfaces were investigated by a light microscopy and, on those surfaces, the average surface roughness R a was measured. The material zone affectted by the laser beam during the cutting process was monitored by a thermal imaging, and theoretical simulations of temperature distribution in this area were performed using the various versions of COM-SOL packages.

“…For blind holes a surface modification is prepared by exposing perspex to laser beam. The thermochemical damages due to carbonization of perspex into small spots are reported [27] - [28]. Conventionally the drilling of perspex establishes the significant parameter to be controlled for effective drilled hole as the speed, feed rate, thrust force, tool wear, delamination [29] - [30] and hole shrinkage.…”
