The development of a model used to describe the mechanism by which vibration assisted machining reduces tool temperature is discussed, and correlations to resulting reduction in tool wear are presented. This model is applied to a newly developed ultr

The development of a tunable ultrasonic vibration-assisted diamond-turning tool is described. The resonance operation method, which formerly served to achieve mechanical motion at ultrasonic frequencies, is now replaced by a newly developed pulse dri

A long-range, precision fast tool servo (FTS) system was developed that is capable of accurately translating the cutting tool on a diamond turning machine (DTM) with maximum accelerations of 260 m s−2 and bandwidths of up to 140 Hz. The maximum dis

Flexure systems are used often in precision motion applications, but are significantly limited in range of motion to prevent high stress build-up and fatigue. A toroidal flexure geometry is presented that relies primarily on shear rather than tensile

The forward and the inverse kinematics solutions for a three dimensional, non-contacting metrology system are presented. The solutions are a continuation of earlier works involving the derivation of an error budget for the metrology system; however,

The purpose of this work is to improve the efficiency of green sand foundries so that they may continue to compete as the most cost-effective method of fabrication while meeting tightening constraints on near-net shape manufacturing. In order to achi

During long duration space flight, astronauts must exercise to prevent bone demineralization. Exercises are used as countermeasures to the bone mineral loss. The effectiveness of the countermeasures is closely related to the mechanical stress develop

Human bodies depend on a steady flow of oxygen for the heart and lungs. When a person has Chronic Obstructive Pulmonary Disorder (COPD), a device called an oxygen concentrator can be used to improve quality of life. An oxygen concentrator is an elect

Under the conditions of weightlessness, astronauts have a tendency to exhibit bone mineral loss in their spines and lower extremities (Oganov et al., 1992). According to Wolf’s law, bone adapts to functional demands by remodeling to reflect the dis
