Comparison of Discrete Part Verification Using Coordinate Measuring Machine and Articulated Arm Coordinate Measuring Machine
Lopez, Andrea (2019-12-13)Quality assurance is key in manufacturing and assembling processes and is usually implemented by specifying and controlling tolerances and surface finish of important features, in discrete product manufacturing industry. ... -
Comparison of Interval Valued Pareto-Optimal Alternatives
Stewart, Andrew (2016)Everyday tradeoff decisions are made where criteria must be compared, evaluated, and decided upon. In real world applications, variables have an inherent amount of uncertainty that must be regarded when making a ... -
Comparison of the Measurement Capabilities of CMM and AA-CMM Machines in Flatness Verification
Marquez Rodriguez, Cesar (2022-05)Manufacturing is among the most important activities contributing to the nation’s economy. Almost everything we see, use, and touch, was made by someone, and now more than ever, quality is paramount across the industry. ... -
Design and fabrication of a 3D printed hybrid implant for temporomandibular joint regeneration
Rassi, Ali (2021)Patients suffering from temporomandibular joint (TMJ) disorders have difficulties performing trivial activities such as chewing, yawning, and even laughing. In severe cases, the pain is unbearable and clinical care is ... -
The design of an experimental testing fixture to test seals of various geometries exposed to extreme operational conditions while operating in dynamic rectilinear motion
Keegan, Jon (2023-05-12)Radial reciprocating seals are available in a multitude of materials and physical configurations. The most used seal configuration is a circular cross section polymer ring shaped seal, O-ring seal. While affordable and ... -
Factors Relevant to Parallelism Inspection
Gupta, Nitya (2017-05)Inspection of parallelism between two surfaces (planes) requires the establishment of a datum feature (surface), and determination of the envelope of points containing the inspected feature parallel to that datum feature. ... -
Galling of Stainless Steels in Low Static Contact and High Cycle Applications
Hatch, Paul (2016)This study was done to examine the mechanisms involved in the galling of stainless steel surfaces which are subjected to low static contact loads while undergoing a high number of sliding cycles. Presented is a theoretical ... -
Graph Isomorphisms and Homeomorphisms for Part and Assembly Matching: Distributed System and Provenance with Blockchain Technology
Kenney (2020-05)In recent times, the democratization of manufacturing through various developments in the industry, such as 3-D printing and crowdsourcing, has led to increasing levels of innovation and a greater ability for smaller ... -
Human-Computer Interface Design in Human Factors: Weapons Drop
Blanche, Elizabeth (2018-12-14)In a technologically advanced world, aircraft users tend to get caught up in all of the automation. However, if the automated function stops working, the users are left with analog skills to meet their mission. For the ... -
Hybrid Decision making model using linear programming and analytical hierarchical process for comparison of manufacturing choices (additive and traditional) ( a pilot study)
Gunturi, Ravi Shankar (2023-12-15)This research is built upon existing knowledge of additive manufacturing and traditional manufacturing to gain insights into the cost differences associated with different manufacturing processes as a pilot study. The ... -
