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: 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: A MACHINING STABILITY MODEL WITH PROCESS DAMPING FOR HARD-TO-MACHINE MATERIALS
Author: Tyler, Christopher
Date Created: 2015
Subjects--Topical: Mechanical engineering
Description: A substantial fraction of current machining research is directed towards increased productivity. A fundamental limitation is unstable vibration, or chatter, during cutting. Stability lobe diagrams, which relate the allowable chip width to spindle ...

Title: FRICTION MEASUREMENT DURING FREE VIBRATION
Author: Kossack, Christoph
Date Created: 2018
Subjects--Topical: Mechanical engineering
Description: Friction is a key consideration in the behavior of many dynamic systems. However, modeling friction behavior accurately remains an engineering challenge. Current friction measurement approaches are limited to application specific tests that attemp...

Title: COMPENSATION OF FREQUENCY RESPONSE FUNCTION MEASUREMENTS BY INVERSE RCSA
Author: Satyanarayana, Harsha
Date Created: 2017
Subjects--Topical: Engineering
Description: The stability lobe diagram is a graphical device used to select stable cutting conditions in machining. The generation of the stability lobe diagram requires the tool-holder-spindle-machine frequency response function (FRF). Therefore, the accurac...

Title: Characterization of the Dynamic Performance of Machine Spindles
Author: Ganguly, Vasishta
Date Created: 2014
Subjects--Topical: Mechanical engineering
Description: Machine spindle dynamics and (axis of rotation) error motions may vary as a function of spindle speed due to gyroscopic effects, changes in bearing preload, centrifugal forces, and thermals effects. It is necessary to characterize these changes in...

Title: Analysis of wound irrigation devices
Author: Pawar, Amogh Madan
Date Created: 2018
Subjects--Topical: Mechanical engineering, Medicine
Description: In wound irrigation, the surface pressure at the wound is critical. Correct pressure ensures removal of bacteria and foreign debris without further tissue damage. Surface pressure measurements were performed for three irrigation devices, including...

Title: THE FRICTION MEASURING MACHINE: AN ENERGY-BASED APPROACH TO FRICTION CHARACTERIZATION
Author: Lomascolo, Christian
Date Created: 2017
Subjects--Topical: Mechanical engineering
Description: Friction has been studied and analyzed through the years. The need for precise friction measurement has become increasingly important as the need for precision positioning mechanism has increased. This precise control of mechanical systems require...

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: The fundamental application of decision analysis to manufacturing.
Author: Karandikar, Jaydeep
Date Created: 2013
Subjects--Topical: Mechanical engineering, Industrial engineering
Description: Machining models are available to predict nearly every aspect of machining processes. In milling, for example, models are available to relate stability, part accuracy (from forced vibrations during stable machining), and tool wear to the selected ...

Title: Time Domain Simulation with Applications in Compliant Workpiece Milling
Author: Rubeo, Mark
Date Created: 2016
Subjects--Topical: Mechanical engineering
Description: High performance application fields, such as the defense, power, and aerospace industries, benefit from the enhanced product quality and reduced cost associated with machining thin-walled, metallic structures over traditional fabrication and assem...
