Abstract

This paper analyses the objective functions that define the dimensional accuracy in case of laser drilling. The initial experiments were made on a Nd:YAG laser with maximum impulse energy of 60 J, impulse length between 0,5-8 ms, impulse frequency between 1 and 100 Hz. These experiments were made on a sample of stainless F17T steel (0,005% C, 0,35% Si, 0,40% Mn, 16,5% Cr, 9,4 Ti), 2,5 mm thickness. As parametres of the laser drilling were considered the following: the energy of the laser impulse, the impulse length, the working gas, the focal spot position related to the processed object surface and the diameter of used midriff. The analysed objective function were: the deviation from the circularity at the upper surface level of the processed material and a note that testify the quality of the hole processed. Using the STATGRAPHICS program, were established the regression polynoms that define the objective function. A comparative analyse of results obtained by the mathematical model and experimental results is also presented. Using two dimensions and three dimensions graphics, the user can quickly find the optimum value of the required parametres for laser drilling.
