Title: A Novel Fluorescence Based Method of Assessing Subsurface Damage in Optical Materials
Author: Williams, Wesley
Date Created: 2009
Subjects--Topical: Mechanical engineering, Materials science, Optics
Description: Lapping and polishing are loose abrasive finishing processes that have been used to achieve critical surface parameters in optical materials for centuries. These processes remove material from the surface through a variety of mechanical and chemic...

Title: DEVELOPMENT OF EXPERIMENTAL FACILITIES FOR INVESTIGATIONS OF VORTEX MACHINING
Author: Howard, Stephen
Date Created: 2014
Subjects--Topical: Mechanical engineering
Description: 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 a polishing slurry above a workpiece, thereby removing material in regions...

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: FIBER BASED TOOLS FOR POLISHING OPTICAL MATERIALS
Author: Shahinian, Hossein
Date Created: 2018
Subjects--Topical: Mechanical engineering, Optics
Description: In this dissertation, the development of alternative fiber based polishing tools for the finishing of precision freeform and aspherical optics is introduced. Freeform and aspherical optics, i.e. optics with varying radius of curvatures (ROC), are ...

Title: POSITIONING SENSOR BY COMBINING OPTICAL PROJECTION AND PHOTOGRAMMETRY
Author: Zheng, Benrui
Date Created: 2014
Subjects--Topical: Optics, Engineering, Remote sensing
Description: Six spatial parameters, (x, y, z) for translation, and pitch, roll, and yaw for rotation, are used to describe the 3-dimensional position and orientation of a rigid body - the 6 degrees of freedom (DOF). The ability to measure these parameters is ...

Title: PRECISION POLISHING DYNAMICS: THE INFLUENCE OF PROCESS VIBRATIONS ON POLISHING RESULTS
Author: Mainuddin, Mohammad
Date Created: 2014
Subjects--Topical: Mechanical engineering
Description: The optical pitch polishing process has been used over 300 years to obtain high quality optical surface finish with little subsurface damage. A pitch tool consists of a metal platen coated with a layer of polishing pitch whereby pitch is a highly ...
