The use of unconventional machining technique for Aluminum based Metal Matrix Composites [MMCs] are generated considerable interest in machining. In the aviation industry, in order to obtain a high precision, a good surface finishing and high working speed, the processing of these hard materials is done with the help of the fiber beam laser). The objective is to determine the mechanical properties of the hybrid composite and further investigate its machinability. The aerospace industry uses the laser machining for its machining process like drilling the cooling holes etc. Standard frequency and variation in other parameters such as pulse width, power, and time will occur the impact in the laser beams composites like diameter and roundness of the hole. Especially, the increase in the variation of power and time plays a vital role in the diameter and roundness of the hole.
