Effect of cutting temperatures on the hole quality of a carbon-fiber composite

Abstract

The drilling of composites project is aimed at minimizing delamination and reducing the fiber pull out, thereby improving the hole quality. The heat generated during drilling has an adverse effect on the hole quality. So it is important to analyze the effect of cutting temperatures on the dimensional accuracy of the drilled hole namely hole oversize and roundness and also its effect on the surface finish/roughness of the drilled hole. The drill bit will also be tested for the same parameters using a mist cooling system. These results will be compared with one another. Also the results of different drill bits will be compared with one another.
