Title: Experimental and computational evaluation of a vibratory finishing process
Author: Navare, Jayesh
Date Created: 2017
Subjects--Topical: Mechanical engineering
Description: Vibratory finishing is among the widely recognized mass finishing techniques which is used for cleaning, deburring, edge rounding, polishing, and creating an isotropic surface finish on metal parts that have undergone previous machining operations...

Title: FREEFORM MEASUREMENT WITH STITCHING TALBOT INTERFEROMETER
Author: Furukawa, Yasunori
Date Created: 2018
Subjects--Topical: Optics
Description: Freeform optics are being used in many fields to realize the outstanding performance due to their high degree of freedom. To realize sufficiently high performance, it is necessary to manufacture the freeform surface with high accuracy, which requi...

Title: FUNDAMENTALS OF MATERIAL REMOVAL IN SILICON CARBIDE FOR FREEFORM OPTICS
Author: Shanmugam, Prithiviraj
Date Created: 2019
Subjects--Topical: Mechanical engineering
Description: The mechanical and thermal properties offered by Silicon carbide (SiC) make it an ideal material for reflective freeform optics. However, the hardness, brittleness and fracture toughness of the material pose a challenge to manufacturing. The manuf...

Title: NONPROPAGATING EXCITATIONS IN 2-D
Author: Abney, Ray
Date Created: 2020
Subjects--Topical: Physics
Description: Nonpropagating excitations have been studied in 1-D and in 3-D, but not so much in 2-D. So, this thesis concerns 2-D nonpropagating excitations. In particular, we construct nonpropagating excitations confined to an annulus under a time-independent...

Title: OPTICAL DISPLACEMENT MEASUREMENT BY IMAGE CORRELATION
Author: Lambert, Nathan
Date Created: 2019
Subjects--Topical: Mechanical engineering
Description: This thesis describes the design and veriﬁcation of a scanning, optical, displacement measurement instrument, which utilizes digital image correlation (DIC) to measure displacement. This system is intended to provide proof of concept for a techniq...

Title: REPLICATION OF FREEFORM OPTICS ONTO NEAR-NET-SHAPE SUBSTRATES USING DIAMOND TURNED STAMPERS
Author: Smith, Glen
Date Created: 2019
Subjects--Topical: Mechanical engineering
Description: Freeform optics open a new design space for optical systems. Production of freeform optics, with no axis of rotational symmetry, often requires the use of multi-axis (>2) sub aperture machining and finishing techniques. These are expensive and imp...

Title: Ultraprecision Diamond Machining of Polycarbonate Complex Multi-Sided Freeform Optics
Author: Swagler, Steven
Date Created: 2022
Subjects--Topical: Optics, Mechanical engineering
Description: Advances in technology are driving optical systems to become more and more complex and compact. Ultra-precision machining centers have advanced to catch up with optical designs but there is a defined set of methods defining the use of the machines...
