Thrust force and tool wear investigation of micro drilling for carbon fiber reinforced polymer (CFRP) material

Micro drilling of Carbon fiber reinforced polymer (CFRP) poses numerous challenges due to its anisotropic structure and non-uniform material properties. High cutting force and rapid tool wear are few of the common problems in dealing with this material which correlate with the drilling parameters. Therefore, understanding on the relationship between the parameters and the materials response is crucial for the success of the drilling process. Experimental micro drilling process with variable spindle speed and constant feed was carried out to investigate the effects of machining parameter on thrust force and tool wear. It was observed that, thrust force and tool wear have small effect towards the parameter range studies. Hence, it can be concluded that the investigation work need to be extends by taking into accounts on the influence of feed rate and range of parameter study.
