Optimization of the Process Parameters for Drilling of Metal Matrix Composites (MMC) Using Taguchi Analysis

Drilling of MMCs is considerably difficult due to the presence of extremely hard reinforcement which causes rapid tool wear and influences the cutting forces and quality characteristics. The present investigation aims at studying the effect of drilling parameters (cutting speed, feed rate and the drill point geometry) on the output responses such as, thrust force (TF), specific cutting pressure (SCP) and surface roughness (SR). Taguchi’s technique has been applied to obtain an optimal setting for drilling process parameters for optimizing the output quality characteristics.
