“…It was found that different irradiating angles in the process result in a variation of the material's removal rate, as well as in the surface roughness. A similar study by Moreno et al [25], in which the effect of the oblique incident angles of the laser beam on the ablation rate of the painted flat surfaces was evaluated, drew the same conclusion. These studies, however, are merely representative for processing flat surfaces and only provide a rough prospect of the laser machining of a nonflat surface.…”

This article discusses the process of the laser turning of rotational symmetric, cylindrical components using ultrashort laser pulses with respect to the geometrical conditions and the resulting energy distribution during the laser turning process. As a result, process predictions and potential process optimizations are feasible. Particular attention is drawn to the laser spot formation on the cylindrical surface of the work piece in conjunction with the positioning of the laser beam relative to the rotation axis of the specimen. Based on fundamental calculations and experimental results, an optimum processing strategy is discussed, whereat the use of a trepanning optic in the laser turning process and the forming of a particular surface structure is additionally being issued.
