The processes in the cutting gap and the achievable quality of laser beam cutting of milled glas fiber enhanced compound materials were investigated in this work. Extensive experimental work was carried out to optimize the quality by identifying process parameters and their effects on cutting edge geometry, tolerances and shape deviation. On this basis characteristic diagrams for cutting quality were developed which are applicable on other CO2 laser machines. The fundamental insight gained by this work allows for quick estimation of the limits of the laser cutting process and fast determination of practicable parameter values. An analytical cutting model for milled glass fiber enhanced compound material was developed which is able to predict the process result with an accuracy of about 6%.
