Abstract
Machining carbon fibre reinforced polymers (CFRPs) still represents a manufacturing challenge due to fibre cutting angle dependent chip formation mechanisms and intense mechanical wear on the cutting tool. With respect to the latter, the wear-related change of the cutting edge micro-geometry usually results in increasing process forces and thus a higher risk for process related workpiece damages. The presented work demonstrates the strong influence of post-coating cutting edge treatments via two-part laser ablation on the process forces and the tool wear behavior. In the scope of this preliminary study, two different microscale geometry modifications are tested. It is shown that a small cutting edge radius in combination with a reduced contact length on the flank face enable significant thrust force reductions over a long lifetime. Show more
