Abstract

High power solid state lasers are increasingly being used for drilling and cutting of advanced materials. This is because of the difficulty in machining, in particular, drilling of small diameter holes, using conventional methods. The pulsed Nd YAG laser is an excellent tool for fine drilling and cutting of these materials because of its combination of high peak power pulse capability and its low beam divergence. A program of experimental work has therefore been carried out to examine the practical effects of key laser variables on the drilling of the Ceramic Matrix Composite material. The parameters used and the systematic approach to the trials is also presented along with information on how statistically significant and repeatable results were obtained.
