The effect of cutting temperature on hole quality when drilling CFRP/metal stack
(НТУ "ХПІ", 2015) Kolesnyk, V.; Zajac, J.; Radchenko, S.; Adamian, M.
The carbon fiber reinforced plastic (CFRP) are widely used in stacks with metals. That allows obtaining components with high strength and reduces weight. Holes’ drilling is a basic operation of CFRP/metal and metal/CFRP stacks machining. The most common problems of CFRP/metal stacks drilling are CFRP delamination, fiber pull – out, thermal degradation and low quality of hole surface. In this study the effect of cut ting temperature on the hole quality was provided. It was experimentally established that drilling of CFRP/metal stack was accompanied with a significant change of cutting temperature in the cutting zone during the transition of drill from CFRP to metal plate.
