Machining carbon composites: Risky business

There is perhaps no portion of the composites manufacturing process that suffers the variables and uncertainties of carbon fiber-reinforced polymers more than machining. Not only has the use of carbon fiber composites increased — on projects as diverse as the F-35 Lightning II, the V-22 Osprey, Boeing's 787 Dreamliner and the Airbus A350 XWB — but the sheer size of composite structures

Machining Carbon Fiber: Quick Guide [ Composites,

Fiber orientation is also important to be aware of when machining carbon fiber and composites. Where possible, the material is damaged the least if you can machine parallel to the fibers. Of course it's often impossible to do so exclusively, but it's worth being aware that machining parallel gives the least amount of fraying, chipping, and delamination.

Ultrasonic

In order to overcome these problems, the ultrasonic-vibration-assisted machining of CFRP is proposed in this study. The cutting force is expected to decrease when axial- directional ultrasonic vibration is applied to the tool as a result of the intermittent cutting process with a large acceleration over a short period, which shown by H. Isobe [1].
