Current fabrication and assembly methods for precision stator and rotor laminations/cores used in strategic guidance system comonents are costly, labor intensive, and stress sensitive procedures. Traditional methods used are pushed to the limit of their state-of-the-art to achieve the high quality standards required of both physical structure and electromagnetic properties. This Phase I proposal examines the applicability of modern millimachining technology to the manufacture of these precision laminations/cores. Millimachining is basically a 1000 times scale up of micro-machining technology. As such, macro-size structures can be made stress free while maintaining the inherent advantages associated with micro-machining such as - high resolution lithography, batch processing, wide choice of materials for etching or layering, and flexibility with use of other in-process technologies. This suggess cost, performance, and new capability advantages are possible with this approach. Initially, simple structures will be made to assess quality of nickel-iron alloy formed by millimachining. Experiments will follow to evaluate process control of critical geometric parameters. Finally a continuous process of fabrication will be evaluated to make a finished core. If this investigation proves successful, a Phase II will be proposed to manufacture rotor and stator laminations/cores for approval by Air Force Design Agency.
