In the recent years there has been an increasing interest in manufacturing products where surface topography plays a functional role. These surfaces are called engineered[...]

Recent advancements in manufacturing and post-processing of optics with sub-aperture methods have enabled greater degrees of freedom to realize complex optical surfaces. [...]

Most of us who are familiar with the term ceramics instantly gravitate towards the image of clay on a pottery wheel undergoing becoming a beautiful work of art in its own[...]

The study of optics has changed over the past 3000 years. We have developed beyond the early lens technologies of quartz and other types of glass materials and new materi[...]

The main focus of this study is on chatter avoidance during machining. Self-excited regenerative vibration or "chatter" is a significant obstacle in machining which resul[...]

Lapping and polishing are loose abrasive finishing processes that have been used to achieve critical surface parameters in optical materials for centuries. These process[...]

Additive manufacturing (AM) offers an industrial solution to produce parts with complex geometries and internal structures that conventional manufacturing techniques cann[...]

This dissertation presents work done in investigation of a novel polishing process called Vortex Machining. Vortex Machining uses an oscillating probe to induce vortices [...]

In this dissertation, the development of alternative fiber based polishing tools for the finishing of precision freeform and aspherical optics is introduced. Freeform and[...]

When inspecting a manufactured part to determine whether it falls within tolerance, it is often important to distinguish the difference between a defect and geometric var[...]
