GE Global Research have developed a machining technology called Blue Arc.The company says Blue Arc can make higher quality metal parts faster and more efficiently than current technology. Blue Arc can cut through tough engineering alloys used in aircraft engines and power generation turbines more quickly than using conventional milling processes. When you see a jet engine up close, it is an impressive sight. Even more impressive is the extensive time and effort that goes into putting these products together. Building these products requires machining off several tons of metal into very precisely designed components. With advanced technologies like Blue Arc, GE says hours, even days can be removed from these manufacturing processes.
