Electrochemical machining is a non-contact machining method that is well suited to the fabrication of complex difficult to machine materials. Unlike conventional machining processes, ECM is not affected by material strength, hardness, or toughness which can cause significant processing time and increase defect rate in high strength materials. High tolerance material removal with superior surface finish is well within the capabilities of ECM however rapid bulk material removal is a challenge. In an effort to improve field readiness and reduced component costs ECM is being applied to the manufacture of complex Inconel 718 components. The use of a rapid material removal will improve the success of this effort and may have future applicability to other Ben t Laboratories mission components. less than br greater than less than br greater than Inconel 718 is used extensively in the aerospace industry for complex turbine engine components. The excellent high strength properties at high temperatures results in a difficult to machine material that adds complexity, cost and time to the manufacturing of components. General Electric (GE) has matured electrochemical machining (ECM) methods to achieve cost effective production of Inconel for aircraft engine components. GE has developed a trademark Blue Arc process similar to ECM to remove large amounts of material more economically than standard ECM. This process is well suited to the rough hole boring of the Inconel 718 for fabrication from solid stock. less than br greater than
