We are studying the frictional conditions at the chip-tool interface, developing methods to measure tool temperatures using infrared sensing, and carrying out finite element simulation of machining. Lapping, Polishing, and Superfinishing of steels and ceramics Models are developed for relating measured forces and pressure to the material removal mechanisms. A new manufacturing process has been developed for slicing ceramics such as silicon carbide, silicon nitride, and aluminum oxide. The above are being investigated to develop processes that do not damage the coatings. The effect of superimposed, low frequency vibrations on the drilling process is being studied.
Potential benefits are easier chip disposal and better hole quality.
These include the development of finite element codes and accompanying experiments to predict microstructure, residual stress, and distortion induced by quenching and carburizing. The above is being investigated using multiaxial fatigue theories, finite element modeling, and reduced experiments to predict the remaining life of aging aircraft joints. This study focuses on development of predictive tools for the effect of manufacturing process parameters on product performance. Naval Surface Warfare Center, and NSF 13. Microelectromechanical Sensors and Actuators Microelectromechanical Sensors and Actuatorsare being investigated as potential tools for measuring torque and localized strains induced by manufacturing processes.
