Title: Characterization of Geometric Surface Features Using Statistically Based Analytical Tools
Author: Azimi, Farzad
Date Created: 2019
Subjects--Topical: Mechanical engineering
Description: The nature and quality of a surface’s topography can play an important role in a part’s performance and expected longevity. The complexity of a surface topography means that while commonly used ISO 25178-2 height based statistical metrics are capa...

Title: DESIGN, TOLERANCING, AND EXPERIMENTAL CHARACTERIZATION OF DYNAMIC FREEFORM OPTICAL SYSTEMS
Author: Shultz, Jason
Date Created: 2017
Subjects--Topical: Optics, Engineering, Physics
Description: Although freeform concepts have been considered for many decades, new fabrication capabilities have enabled new classes of optical components and sparked greatly increased interest in freeform optics. Generally defined as surfaces without rotation...

Title: DUCTILE MACHINING OF CRYSTALLINE MATERIALS WITH VARIABLE RAKE SINGLE POINT DIAMOND MACHINING
Author: Griffin, Adam
Date Created: 2019
Subjects--Topical: Mechanical engineering, Materials science
Description: The effect of a variable rake machining process such as Fast Tool Servo (FTS) on optical IR crystalline materials isn’t well understood and can be difficult to test. This thesis proposes and develops the concept of using a 'starburst' cut geometry...

Title: DYNAMICS SENSITIVITY STUDY OF STOCK CAR SHIFTER COMPONENTS
Author: DesRocher, Samuel
Date Created: 2016
Subjects--Topical: Mechanical engineering, Automobiles--Design and construction
Description: Previous experience in race situations has shown that components in the shifter section of the stock car drivetrain are subject to failure. As the engine operates in a specific rotational speed band throughout a race event due to gearing rules, th...

Title: Design for Metrology of Freeform Optics
Author: Venditti, Kristen
Date Created: 2020
Subjects--Topical: Mechanical engineering, Optics, Engineering
Description: Freeform optics offer significant advantages over the conventional aspheric optics, but pose new challenges in metrology and manufacturing. The spatial frequencies of an optical surface that must be measured have changed due to the progression of ...

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 ...

Title: Period-n Bifurcations in Milling
Author: Honeycutt, Andrew
Date Created: 2018
Subjects--Topical: Mechanical engineering
Description: Period-n bifurcations in milling operations are studied in this dissertation. Period-n bifurcations represent a special type of unstable dynamic behavior because they have a response period that is an integer multiple (n) of the forcing period. Th...

Title: SEMI-ANALYTICAL MODEL FOR THIN PLATE DYNAMICS
Author: Menezes, Joyson
Date Created: 2016
Subjects--Topical: Mechanical engineering, Aerospace engineering
Description: Productivity when milling thin, monolithic components is often limited by regenerative chatter. The vibrations are partially controlled by the use of stability lobe diagrams, which enable the selection of spindle speed/axial depth combinations to ...

Title: Sub-scale Machining of Large Components
Author: Anderson, Paul
Date Created: 2015
Subjects--Topical: Mechanical engineering
Description: This research examines the feasibility of machining components with precise tolerances using machines smaller than the completed part. This can conceptually be achieved in two ways. 1.) move a part around a machine, machining a portion of the part...
