Chemical vapor deposition of diamond material helps reduce cutting time, increase quality for JSF wing skins
3/1/2008
Who wouldn’t give $105,000 to gain $222 million? Lockheed Martin Aeronautics Co. (LMAC, Ft. Worth, Texas) did and in the process was able to fabricate dimension-critical aerostructures more efficiently, more accurately, and faster. LMAC is a major components manufacturer for the F-35 Joint Strike Fighter (JSF), the

Plasan USA (Bennington, Vt.) molds the Chevrolet Z06 Corvette’s front fenders with hand layed, autoclave-cured carbon/epoxy prepreg. Until recently, however, manual deflashing, trimming and drilling of the demolded parts consumed more than an hour to meet requirements for edge quality and fastener hole location

Overview Of:

Cutting, Nesting, Machining Technology

 

Cutting is typically used to cut carbon fiber and glass fiber fabrics to a specific shape to meet design and part performance requirements. These cut fabrics then are usually placed in or on a tool in a specific location, determined by the part design. Automated cutting can be done on cutting tables, with fabric laid flat and a computer-controlled cutting head moving over it to cut shapes. Nesting refers to the layering of cut fabrics within a part or structure to optimize strength and rigidity

Machining typically is done on finished composite components and structures in order to trim the part, drill holes, or to remove excess material, or deflash. Such machining is usually done with metallic bits that use a highly abrasive-resistant material, such as carbide or a diamond coating. Alternatively, composites can be cut with a waterjet system that shoots a stream of ultra high-pressure water through a nozzle to generate a cutting action, or with lasers.
