Electrode Machining Set Free
These two shops used to mill EDM electrodes on their metal cutting machines, but they have now shifted the work to graphite machining centers. Both shops say the advantage isn’t just in the cycle time savings, it’s in the inefficiencies they can now overcome.

Find The Right Speed For Chatter-Free Milling
It used to be that a little chatter was easy to forgive. Not anymore. In shops aiming to minimize hand finishing, machined surfaces have to be smooth. And in high speed machining applications, chatter itself can set the speed limit.

High Speed Machining: Aerospace -- Boeing's One Part Harmony
Faster, lighter cuts can let one solid part replace an assembly of hundreds of components. Better manufacturing and a better airplane both result. But before Boeing could realize these benefits, a more finely tuned process was needed.
