Optical attributes influence on mechanical properties of laser cutted PMMA

摘要

The article describes and characterizes the technology and principle of laser cutting PMMA material. Experimental samples with thickness t = 3 mm of PMMA were made with a constant optimized technological parameters of laser cutting. In the experimental part are compared values of hardness of cutted surface, tensile strength of different colour variations and impact on selected mechanical properties by change of technological procedures of selected material processing - tempering of plastics.
