Development Of An Additive Manufacturing Compression Molding Process For Low Cost In-House Prototyping, Grant Forrester Warden
Development Of An Additive Manufacturing Compression Molding Process For Low Cost In-House Prototyping, Grant Forrester Warden
Industrial and Manufacturing Engineering
Composite parts can be manufactured using various processes. Generally, a mix of resin and fiber is formed into the desired geometry using a mold and pressure. One process used by Dr. Joseph Mello in his research is known as compression molding. Compression molds are generally made from large billets of aluminum or stainless steel, are machined by a CNC mill, and are then hand-finished with polishes and mold preparation products. This process is expensive, requires large machinery and experienced operators, and introduces long lead times relative to the design cycle of the part being manufactured. The nature of Dr. Mello's …

Slm Materials Development, Justin G. Reiner, Michael T. Schembri
Industrial and Manufacturing Engineering
The purpose of this project was to create a procedure to efficiently determine a “recipe” of parameter values that create a desired set of mechanical properties. Research was conducted into the laser powder bed fusion process with focus on underdeveloped materials. A design of experiment was used with a set of density correlated parameters to establish a method of producing nearly dense parts. Our methods include SLM printing, metrology, and statistical analysis. An experimental procedure for materials development was designed, but unable to be validated during the scope of this project, due to unforeseen safety issues (exposure to Chromium 6, …
Crystal Engineering Manufacturing Facility Analysis, Maximiliano Cortes, Eric Dustin Kornrumpf, Sthefano Alvarado
Crystal Engineering Manufacturing Facility Analysis, Maximiliano Cortes, Eric Dustin Kornrumpf, Sthefano Alvarado
Industrial and Manufacturing Engineering
This report will encompass a two-quarter long senior project effort to provide a recommendation for the client, Crystal Engineering. Crystal Engineering is currently in the process of introducing three new products, one now and two within the next six months. However, their existing lines already occupy the available production space and as a result, they are unable to determine how to effectively incorporate new production lines within the facility. Therefore, the main objectives of this project were to deliver several facility redesign layouts backed by a holistic justification for each. The formulation of the facility redesign layouts incorporated several industrial …
A Study Into The Production Efficiency Of Cal Poly Chocolates, Fernando Calderon
A Study Into The Production Efficiency Of Cal Poly Chocolates, Fernando Calderon
Industrial and Manufacturing Engineering
The project objective was to: identify ways to reduce the production cost of Cal Poly Chocolates. The project was executed through the DMAIC approach, a data driven improvement cycle. Using several industrial engineering tools, six improvement opportunities were found. Three project deliverables were created and three process changes were recommended. The total annual savings, if recommendations are implemented, sum to $1700.
Design For Manufacturability: Off-Road Toyota Bumper, Drew Donlon
Design For Manufacturability: Off-Road Toyota Bumper, Drew Donlon
Industrial and Manufacturing Engineering
The purpose of this project is to design a new off-road bumper that is improved from the stock form of a 1996-2002 Toyota 4Runner and a 1996-2004 Toyota Tacoma. The current state of the component is too weak to endure to off-road endeavors, and a kit bumper market is virtually untapped for these vehicles. The objectives of this project were met by redesigning the stock front bumper, conducting a finite element analysis on the model to test for strength, prototyping the bumper with CNC cut cardboard, and conducting a full cost analysis including the costs for waterjet and laser cutting …
Wasco Environmental Chamber System Manifold, Steve Mark Yatco
Wasco Environmental Chamber System Manifold, Steve Mark Yatco
Industrial and Manufacturing Engineering
This report details the process of designing and producing a manifold that connects ultra-high purity (UHP) pressure and vacuum switches to an air supply so that the parts may be tested in an environmental chamber. Using the DMAIC (define, measure, analyze, improve, and control) methodology of problem solving, progress on the project includes thorough research about the problem, preliminary design solutions, iterative prototyping, and testing specific functionalities. Manufacturing engineering topics of tooling, fixturing, metrology, quality, and machining with manual and computer numerical control (CNC) varieties of both mills and lathes are applied during the course of the project. The report …
S&G Metal Fab Battery Tray, Matthew Nartatez
S&G Metal Fab Battery Tray, Matthew Nartatez
Industrial and Manufacturing Engineering
This report was written for the design of a battery tray and manufacturing process for S&G Metal Fab. The manufacturing steps of how to process the sheet metal to create the product are defined and documented in this report. This project began with constraints given by S&G and were all accomplished using coursework knowledge obtained as a manufacturing engineer student at Cal Poly San Luis Obispo. This report mainly covers parameters regarding the cutting, bending and, deforming of sheet metal to acquire the desired shapes and sizes. It also analyzes the costs that are associated with these processes and material. …
The Design, Testing, And Manufacturing Of A Pin Fin Extrusion Heat Sink, Arash Michael Mira
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, …
