The Design, Testing, And Manufacturing Of A Pin Fin Extrusion Heat Sink, Arash Michael Mira

Industrial and Manufacturing Engineering

My senior project focuses on the design, testing, and manufacturing of pin fin extrusion heat sinks that are you used to cool simple electronic applications across a multitude of markets. Without the modern day heat sink, electronics that we have become familiar with throughout our everyday lives will cease to exist. I will design these heat sinks using Solid Works 3D CAD. I will then test the heat sinks using ICEPAK CFD software, where I will model the heat sink against a 5 watt application, inside of a cabinet that models the chassis of a computer. After receiving these results, …

High Speed Turning Of Compacted Graphite Iron (Cgi) Using Controlled Modulation, Tyler Paul Stalbaum

Open Access Theses

Compacted graphite iron (CGI) is a material which emerged as a candidate material to replace cast iron (CI) in the automotive industry for engine block castings. Its thermal and mechanical properties allow the CGI-based engines to operate at higher cylinder pressures and temperatures than CI-based engines, allowing for lower fuel emissions and increased fuel economy. However, these same properties together with the thermomechanical wear mode in the CGI-CBN system result in poor machinability and inhibit CGI from seeing wide spread use in the automotive industry.

In industry, machining of CGI is done only at low speeds, less than V = …

Identification Of Rework Station Location To Enhance Reworkability Using Design For Disassembly, Juan Alejandro Saavedra

Open Access Theses & Dissertations

Rework stations are commonly established as part of each assembly stations causing the material flow of the process to be constantly interrupted. Another option is to place the rework station at the end of the production, but this is not cost effective. This breakeven point between reworkability and cost methodology has been proposed in this thesis to identify the location of a single rework station in an assembly line in order to enhance reworkability using the Design for Disassembly (DfD) principles. The methodology uses the 17 guidelines of DfD in a manufacturing scenario in order to propose a reworkability index …

Extending Origami Technique To Fold Forming Of Sheet Metal Products, Ala Qattawi

All Dissertations

This dissertation presents a scientific based approach for the analysis of folded sheet metal products. Such analysis initializes the examination in terms of topological exploration using set of graph modeling and traversal algorithms. The geometrical validity and optimization are followed by utilizing boundary representation and overlapping detection during a geometrical analysis stage, in this phase the optimization metrics are established to evaluate the unfolded sheet metal design in terms of its manufacturability and cost parameters, such as nesting efficiency, total welding cost, bend lines orientation, and maximum part extent, which aides in handling purposes. The proposed approach evaluates the design …

Emergency Response Manufacturing: Lead Time Minimization And Human Factors For Ozone Water Filter Assembly And Kitting Process, Travis Gary

Industrial and Manufacturing Engineering

In the unfortunate event of a natural disaster affecting San Luis Obispo, response from national entities cannot be relied upon for a timely or efficient response. Local disaster recovery is superior because it minimizes response time, the need for costly stockpiling and creates a solution that is uniquely suited to the community that empowers local people in their most troubled times. Extensive planning is required for local disaster recovery and this project aims to provide the research and recovery system design required to implement an effective recovery plan.

Potable water is the primary need for people in the disaster situations …

Design For Manufacturing Of Sports Equipment, Cedrick Bit, Christopher L. Head

Industrial and Manufacturing Engineering

The purpose of this project was to validate industrial designs for a product in its conceptual stage and suggest/implement design changes that suit the contracting company’s needs while assuring the product maintains its basic functional requirements. Techniques and methods used to validate the design include 3‐D solid modeling, physical product application using rapid prototyping to produce the product. Methods of design for manufacturing were analyzed in the design. Processes used in the validation and verification of the design include solid modeling design, methods of measurements, fixture design and manufacturing processes. Full design specifications and solid model files were finalized and …

Automated Fixture Design For A Rapid Machining Process, Wutthigrai Boonsuk, Matthew C. Frank

Faculty Research & Creative Activity

Rapid prototyping techniques for CNC machining have been developed in an effort to produce functional prototypes in appropriate materials. One of the major challenges for rapid machining is to develop an automatic fixturing system for securing the part during the machining process. The method proposed in this paper is the use of sacrificial fixturing, similar to the support structures in existing rapid processes like Stereolithography. During the machining process, sacrificial supports emerge incrementally and, at the end of the process, are the only entities connecting the part to the stock material. This paper presents methodologies for the design of sacrificial …

Lean Erp Systems: Existence And Viability In Today's Manufacturing Industry, Miroslav Djuric

Master's Theses

This thesis evaluates the existence and viability of lean ERP systems in today’s manufacturing industry. Results from the research show that current practitioners of lean – who also utilize ERP systems – do not have a strong enough link between the two to consider their ERP systems, and overall organizations, as being truly lean.

Few articles and research papers in today’s body of knowledge contain information on the concept of lean ERP. A survey, sent to numerous industry professionals and posted on lean manufacturing websites, provided the results necessary for statistical analysis. The conclusions obtained from this survey analysis provided …

Parallel Simulated Annealing For Scheduling Agile Manufacturing Systems, Ahmed Osama Abdulrahman

Archived Theses and Dissertations

The problem addressed in this research is the scheduling of an agile manufacturing system comprised of machining and assembly operations with the objective of minimizing the makespan. This problem has been addressed in the literature using heuristics and metaheuristics. In addition, a lower bound has been developed. This research builds upon the findings of the recent literature and proposes two enhanced algorithms, parallel simulated annealing and parallel modified simulated annealing, to solve the addressed problem. The performance of the developed algorithms is compared to that of another simulated annealing algorithm that is available in the literature. Performance comparisons are based …

Development Of A Method For Determining The Relative Manufacturing Complexity Of Advanced Engineering Materials, Shardul Y. Pandya

Engineering Management & Systems Engineering Theses & Dissertations

The immediate adaptation of newly developed materials--with unique and highly desirable properties--is hampered by several factors, including: (1) high material cost and limited availability, (2) lack of information on them, including prior experience in their design and manufacture, immature manufacturing processes and general uncertainty in their behavior patterns, (3) unique handling issues, such as excessive manual labor, high process temperatures, toxicity, disposal problems, limited working lives, and low damage tolerance

Therefore, in spite of their significant benefits, potential users tend to shy away from the widespread use of new materials, instead preferring conventional and tested materials forms.

This dissertation is …

Quality Problems Facing Tanzanian Industrial Firms, M Msafiri

Tanzania Journal of Engineering and Technology (TJET)

This paper reports on the results of a study of quality problems facing Tanzanian industrial firms. The results show that Tanzanian firms do not set goals with respect to quality and quality management, thus their qual- ity performance is generally poor. A Ithough there are a number of opera- tional problems constraining the companies, the main problems lie with the internal management of the quality function. Extensive ideas and sug- gestions for improving the performance of the quality function are given.
