Proposed project is to incorporate robot grinding with a state of the art vision system. grinding would be computer controlled by using position data from 3d vision system. vision system would tranglate on surface of propeller using laser light source scanning the surface and 2d camera with… More

Jet engine combustion chambers routinely require repair by removing cracked sections and welding in new ones. laser cutting and welding mke it possible to perform these repairs much faster. integration of the laser with a robot would make it possible to perform the repairs semi-automatically. this… More

The objective of phase i is to define the materials and techniques required to fabricate sealed cvl tubes. a selection of the materials and techniques thought to be useful in the manufacture of such tubes will be made based on prior experimental data and theoretical predictions. screen testing,… More

The objective of this investigation is to produce a technique for joining a sapphire window of optical quality to a body, also composed of sapphire, by a bonding process such that substantially no foreign materials are included in the joint. the ideal resulting process will produce a single crystal… More

The development of a fast, flexible, temporal, spatial, and spectrally resolved camera for medical endoscopic use offersthe promise of a quantum advancement in laser endoscopic surgery. such a camera would help advance spectroscopic research in discriminating healthy tissue from unhealthy tissue.… More

Automated welding has the potential to improve weld quality and reduce scrap rate. if parts to be welded are accurately positioned and fitted, nc type processing can be successfully carried out. the jigs and fixtures necessary to provide the accurate positioning are single purpose and expensive.… More

Hydrostatic extrusion is an advanced high technology for metal working and is ideally suited for difficult-to-form materials, such as al-li alloys. it employs high fluid pressure to extrude a billet through a die, taking advantage of the pressure induced increase of ductility of the billet material,… More
