Abstract

Nd:YAG laser provides efficient and precision drilling of variety of components particularly in aerospace applications. In this paper experimental investigation into influence of laser machining parameters pulse frequency pulse width, gas pressure on the taper and MMR(Maximum Metal Removal) of the machined hole has been performed. Response surface methodology optimal parametric analysis has been performed to determine optimal setting of the process parameters. Minimum taper has been obtained as 0.03121 when the parameters pulse frequency, pulse width, gas pressure are set at optimal parameter setting of 11Hz ,5ms and 8bar respectively. Maximum value of MMR(Maximum Metal Removal) has been obtained as 0.9472 x10-3 g/s when the parameters pulse frequency, pulse width, gas pressure are set at optimal parameter setting of 14Hz ,5ms and 8bar respectively. Analysis has also been carried out for multi-optimization of both the responses taper and MMR. Also the variation of material composition in recast layer and heat affected zone (HAZ) has been studied.
