Analysis Of 3d Printer Schedule, Colin B. Mclane

Industrial and Manufacturing Engineering

With recent innovations in technology, 3D printing has become a rapidly expanding manufacturing method that is being used for a wide range of applications. Their ability to build parts layer by layer instead of cutting away initial material allows this method to have almost no wasted material, creating the potential for a much more efficient, cost effective process. In order to continue the growth of this manufacturing strategy, the performance of 3D printers need to be enhanced to ensure equal or higher quality of produced parts in comparison to other manufacturing methods that are more commonly used. One important part …

Cost Effective Analysis Of Big Data, Steven J. Litzsinger, Nehad Dababo

Industrial and Manufacturing Engineering

Executive Summary

Big data is everywhere and businesses that can access and analyze it have a huge advantage over those who can’t. One option for leveraging big data to make more informed decisions is to hire a big data consulting company to take over the entire project. This method requires the least effort, but is also the least cost effective. The problem is that the know-how for starting a big data project is not commonly known and the consulting alternative is not very cost effective. This creates the need for a cost effective approach that businesses can use to start …

The use of automation systems will be analyzed for their increased consistency, quality, safety, and production estimates. Specifically robotic cell design will be considered, since it can work on more parts with fewer operators, adding efficiency and flexibility to the production floor. Other areas of …

Dcpp/Polygait Inventory Control System, Logan Pace, Robert Garlinghouse

Industrial and Manufacturing Engineering

This report discusses a proposed system to improve upon inventory management issues experienced in the M&TE Tool room for the PG&E Diablo Canyon Power plant. Effective inventory tracking and management is an important characteristic of any organization handling physical assets, and without the proper system in place, companies may lose expensive items and waste time by not having equipment available when needed. The tool room is experiencing inventory shrinkage of M&TE equipment nearing $100,000 per year largely because of an inefficient checkout system that fails to keep employees accountable for the tools they check out. Even more costly than the …

San Luis Obispo Children's Museum: The Circuit Lab, Megan Garcia, Victoria Higgins, Michael Xie

Industrial and Manufacturing Engineering

Executive Summary

Over a nine month period, the senior project team worked closely with the San Luis Obispo Children’s Museum to develop a new interactive exhibit for the museum’s Science, Technology, Engineering, and Mathematics (STEM) floor. The initial budget given for this project was $3,000. The museum’s requirements for a new exhibit were that it must be safe for young children to use, require minimal supervision, is interactive, has learning objectives, and is economically feasible and sustainable. The team chose to build an exhibit that would teach young children about simple circuitry and electronics.

First, extensive research of circuits, children’s …

Human Powered Vehicle Frame Design, Matthew S. Allen, Peter B. Aumann, Trent J. Hellmann

Mechanical Engineering

This report discusses the Human Powered Vehicle Frame Design senior project’s contributions to the design, manufacture, testing, and competition of the Cal Poly Human Powered Vehicle Club’s 2015 vehicle, Sweet Phoenix. The project’s guiding rules and timeline were dictated by the ASME Human Powered Vehicle Challenge (HPVC), held in April 2015. The Club sought to improve upon its previous vehicle, Aria, which suffered from a range of faults including a catastrophic structural failure at the 2014 HPVC. Largely in response to this failure, the Frame Design project’s major focus was Sweet Phoenix’s frame, from concept to manufacturing. During the design …

Warpage And Shape Distortion In Laser Metal Sintering, Xuan Wang

Industrial and Manufacturing Engineering

Selective Laser Sintering (SLS) is the primary method to fabricate metal and ceramic components in additive manufacturing. Due to the anisotropy of powder material, the sintering rate difference will inevitably causes shape change, distortion , and other defects of sintered parts. In this paper, a continuum model was developed to simulate the SLS process. The developed model has been successful to predict sintering kinetics. The impact of processing parameters, such as laser power, scanning speed, hatching distance, and particle size has been studied . The proposed method provides an innovative tool to optimize SLS process parameters.

A Case Study Of Multiple-Use Finish Electrodes For Die-Sinking Edm, Troy A. Robertson

Masters Theses & Specialist Projects

This study examines the use of one finishing electrode to finish multiple dies without remachining the electrode. The multiple-use electrode finishing experiment in this study addresses technology in the die-forging industry. Methods of manufacturing spherical straight bevel forge gear dies have relied on die-sinking Electrical Discharge Machining (EDM) practices that showed great potential for advancement. The focus of this study is solely on the improvements of electrode use in EDM finishing-processes. The surface finish quality itself is not an area of concern other than maintaining that it does not diminish. The focused concern is maximizing the process by using one …
