Developing Control System For Manufacturing Processes, Md Shahriar Forhad

Theses and Dissertations

Process control has been a critical component in today's manufacturing industry. Industrialists nowadays want reliable control to assure precision manufacturing. Modern control systems must be more dynamic, so that any needed modifications may be made quickly to accomplish the desired product change. For innovative research and development, system customization is critical to ensure freedom for experimental works. In addition, full control of manufacturing systems is necessary to realize and implement Industry 4.0. Often, it is difficult to achieve such control due to limited access to proprietary equipment. To this end, this thesis focuses on developing a custom control platform for …

The Influence Of Diversity Dimensions On Student’S Collaboration Success: What It Means For Workforce Development In Manufacturing, Oyinkansola Adeite

All Theses

Manufacturing productivity is measured by labor productivity which is the hourly output of the manufacturing economy. The recent reduction in productivity numbers by the United States Bureau of Labor Statistics emphasizes the need for workforce development. With globalization and technological advancements, diversity has emerged as a critical aspect for the workplace. By encompassing dimensions such as education, race, and age, diversity creates a tapestry of unique perspectives and experiences. This study’s aim is to figure out the effect of a diversity dimension on team performance using intelligent systems, and in addition, if extra dimensions of diversity further impact team performance. …

Parametric Bicycle Yoke, Colin Reay, Walter Minehart, Robby Harrigan, Jordan Olson

Mechanical Engineering

This report outlines the entire design, fabrication, and validation process of a parametric yoke design that addresses the packaging problem of the bottom-bracket chainstay junction in modern bicycle frames. The goal was to create an elegant, space-efficient solution that is accessible to the Cal Poly Bike Builders Club. The report includes documentation of the three-part fixture system, manufacturing process, and testing results for the yoke.

Our yoke design outperforms traditional round-tube weldments in torsional and vertical stiffness. Additionally, all manufacturing fixtures and machining operations function as intended, resulting in a finished yoke that meets all required tolerances in under an …

Crafting Comfort: The Design And Production Of A High-End Poolside Lounge Chair, John Hollis Tackett, Robert Griffis

Honors Theses

This report focuses on the development, design, and manufacturing of the Adjustable Lounge Chair, a high-end poolside lounge chair created to address un-met customer demand in the market. The investigation began with a market analysis to identify sought-after features not currently offered by competitors' products. This analysis drove the design of the chair, which was developed using CAD software, followed by the construction of a physical prototype to validate the concept.

The chair's innovative features include adjustable lumbar support and chair height, as well as a removable face-piece that enables users to comfortably lie prone without straining their necks. These …

Structural Design And Fabrication Of A Test Chamber To Test Ppes For Effective Particle Filtration, Matthew G. Adharsingh

Honors College Theses

This research project aims to design and fabricate a test chamber for testing Personal Protective Equipment (PPE) to ensure effective particle filtration. The chamber has a special purpose, which is to measure ultrafine and submicron particles concentration in the air and test the ergonomic design of PPE based on its effective filtration. The project also considers the environmental aspects of the chamber such as the level of noise and vibration. The chamber will be designed to measure upstream and downstream particle count. Initially, the chamber was going to be made from wood, but the research team encountered difficulties in the …

Strategies To Increase Competitive Advantage In The Automotive Manufacturing Supply Chain, Amber Willis

Walden Dissertations and Doctoral Studies

Some automotive manufacturing supply chain leaders lack strategies that are needed to implement information technology (IT) systems. Business leaders are concerned with implementing IT systems to achieve and maintain a competitive advantage. Grounded in the resource-based view theory (RBV), the purpose of this qualitative single case study was to explore information system strategies used by leaders in the automotive manufacturing supply chain to achieve competitive advantage. Participants were five leaders of an automotive manufacturing supply chain organization who implemented IT systems. Data were collected through semistructured interviews and a review of organization project documents. Through thematic analysis, five themes were …

Rc Baja Suspension And Steering, Garrett Bailey

All Undergraduate Projects

The RC Baja team set out to engineer and construct a working remote-control device that can compete in the ASME Baja Competition. The students have a focus on either suspension and steering or drivetrain and chassis. This report is centered on the suspension and steering. First, multiple analyses were completed using engineering methods such as mechanical design, statics, strengths of materials, and dynamics for parts of the device. The calculations found in the analysis are then used to create designs for the parts so that they will meet the requirements and be successful in the competition. After the parts are …

Rc Baja Project: Suspension And Steering, Chance Hills

All Undergraduate Projects

Students designed and manufactured an RC Baja car to compete in the ASME RC Baja competition. The goal of this section of the project was to create a steering system and suspension system that work together properly with a partner’s chassis/drive train systems during tests and competitions. The car needed to be able to complete in the three events, which are a drag race, a solemn course, and the Baja event. The RC will also be evaluated on the ability to climb inclines, top speed, and withstand the drop test. This proposal will explain all the details and effort that …

Studying And Troubleshooting Lubricity Test On Pressure Wire X Proximal And Distal Coatings, Usama A. Khan

All Graduate Theses, Dissertations, and Other Capstone Projects

Coatings of guidewires used in medical device manufacturing industry are one of the most important element aspects. It defines its efficiency to penetrate through tightest of canals and curves. Guidewires are put through controlled environment to accelerate its age and tested for its mechanical features. Pressure Wire X failed the lubricity testing after being tested by multiple operators and at alternate sites. A cause-and-effect diagram shows all potential causes of test failure. The human factor involved in the test failure was investigated through multiple Gage R&R and training records. Calibration error with the lubricity tester DL1000 was identified and solved …
