Bbt Acoustic Alternative Top Bracing Cadd Data Set-Norev-2022jun28, Bill Hemphill Jul 2022

Bbt Acoustic Alternative Top Bracing Cadd Data Set-Norev-2022jun28, Bill Hemphill

STEM Guitar Project’s BBT Acoustic Kit

This electronic document file set consists of an overview presentation (PDF-formatted) file and companion video (MP4) and CADD files (DWG & DXF) for laser cutting the ETSU-developed alternate top bracing designs and marking templates for the STEM Guitar Project’s BBT (OM-sized) standard acoustic guitar kit. The three (3) alternative BBT top bracing designs in this release are
(a) a one-piece base for the standard kit's (Martin-style) bracing,
(b) 277 Ladder-style bracing, and
(c) an X-braced fan-style bracing similar to traditional European or so-called 'classical' acoustic guitars.

The CADD data set for each of the three (3) top bracing designs includes …

STEM Guitar Project’s BBT Acoustic Kit

This electronic document file set covers the design and fabrication information of the ETSU Guitar Building Project’s BBT (OM-sized) Side Mold Assy for use with the STEM Guitar Project’s standard acoustic guitar kit. The extended 'as built' data set contains an overview file and companion video, the 'parent' CADD drawing, CADD data for laser etching and cutting a drill &/or layout template, CADD drawings in AutoCAD .DWG and .DXF R12 formats of the centerline tool paths for creating the mold assembly pieces on an AXYZ CNC router, and support documentation for CAM applications including router bit specifications, feeds, speed, multi-pass …


Parametric Design Of Flywheel For An Electric Punch Press, Prashant Dhakal Apr 2021

Parametric Design Of Flywheel For An Electric Punch Press, Prashant Dhakal

Honors Theses

Almost all designs start with a design requirement. These may be weight, volume, clearance, and even custom calculations. Finding a solution that meets these requirements often involves tedious and time-consuming iterations. Once the solution has been found, the design must be optimized to find the best possible solution. Finding the ‘best possible design’ requires substantial time and effort dedicated to iterating and analyzing the potential model solutions. This is where Parametric design comes into play. The Parametric design aids in specifying the key parameters of the design and makes changes interactively, with the model updating automatically. The purpose of this …


Analyzing The Lifecycle Of A Modular Cutting Board From Design To Production, Caitlin O'Connor, Achintya Prasad Apr 2021

Analyzing The Lifecycle Of A Modular Cutting Board From Design To Production, Caitlin O'Connor, Achintya Prasad

Honors Theses

This Capstone project is intended to demonstrate the process of product development for a modular cutting board from design to production by applying manufacturing principles, utilizing the stage-gate format, and developing a marketing plan. The guiding principles for the project would be the implementation of lean manufacturing and analyzing the quality, performance, lifecycle cost, and time needed for market introduction. Team voting and assignment occurred in Manufacturing 451 in Fall 2020, and the project was completed during Spring 2021. Teams were required to meet outside of class time in order to discuss ideas and build designs. Lab times were scheduled …


Utilizing Vr For Manufacturing Learning And Training, Jetrin Wichienwidhtaya Apr 2021

Utilizing Vr For Manufacturing Learning And Training, Jetrin Wichienwidhtaya

WWU Honors College Senior Projects

This paper looks into the world of virtual reality as seen from the manufacturing point of view, specifically inside manufacturing education. Virtual reality is growing within many industries including manufacturing and is a key piece in Industry 4.0. Every year, the capabilities of virtual reality grow as the resolution of screens progresses to the point where it can simulate near-perfect depictions of reality as processing power continues to grow. This opens a massive amount of potential into things like training. Especially in the current environment where learning virtually has become the norm, being able to have hands-on experience can help …


Project Daedalus: An Additive Manufacturing Vending Machine, Paul A. Galarnyk, Roxanna Stein, Priscilla Mcdonald, Sky Comarsh White, Matthew Caixeiro, Alexander Seifans, Chris Hays, Benjamin Sallick, Katherine Mcbrayer, Skyler Singleton, Scott Wt Kent Sep 2016

Project Daedalus: An Additive Manufacturing Vending Machine, Paul A. Galarnyk, Roxanna Stein, Priscilla Mcdonald, Sky Comarsh White, Matthew Caixeiro, Alexander Seifans, Chris Hays, Benjamin Sallick, Katherine Mcbrayer, Skyler Singleton, Scott Wt Kent

Student Works

The project was a research endeavor focused on designing and building a vending machine for 3D-printed parts. It also had the secondary objective of catalyzing leadership qualities among its membership by emphasizing individual responsibility and forward thinking. The project began in the spring of 2015, when the topic of autonomous 3D-printing was chosen, funding was secured, and the majority of the leadership was brought on. Over the summer and into the fall semester the team developed project requirements and infrastructure, and gathered members from the parent organization. By December of 2015 most of the machine design had been completed, and …


Determining The Print Accuracy Of Four Three-Dimensional Printers, Kshiteej Dalal Aug 2016

Determining The Print Accuracy Of Four Three-Dimensional Printers, Kshiteej Dalal

Master of Technology Management Plan II Graduate Projects

Rapid prototyping [RP] or 3D printing [3DP] have existed for some time now. One of the major deficiencies of 3DP is the accuracy of the printed three dimensional parts. Even beyond that is the lack of studies that have been designed to measure the 3DP components. Measuring, verifying and determining the accuracy of 3DP parts is the focus of this study. As the accuracy is measured and approaches those of CNC machined parts, it will drive the development of additional additive manufacturing [AM] machinery. In this project a component is created in a solid modeling package. A solid model of …


Asme Mini-Baja Rc Car (Steering And Suspension Systems), Michael E. Cox Jan 2016

Asme Mini-Baja Rc Car (Steering And Suspension Systems), Michael E. Cox

All Undergraduate Projects

The issue that this project is concerned with is how to design and build a drivetrain, steering and suspension systems for an RC car. The systems must be simple and functional. Furthermore, these systems will be designed to fit on a small chassis and not interfere with each other. They also need to be strong and durable enough to propel the car forward and maneuver through various obstacles and be built in a way that is easy to take apart and repair quickly. These design problems were approached using basic mechanical design concepts such as gear kinematics, spur and bevel …


Merging Creative Design And Cad Learning Activities In A Product Design Programme, Pearl O'Rourke, Colm O'Kane, Leslie Smith, Michael Ring Sep 2013

Merging Creative Design And Cad Learning Activities In A Product Design Programme, Pearl O'Rourke, Colm O'Kane, Leslie Smith, Michael Ring

Conference Papers

Traditional learning and teaching methods for creativity differ from those used in a scientific context. Although the creative process can benefit from a certain level of prescription and structural constraint - with time allocated to research, problem definition, conceptualisation and idea development - flexibility and fluidity are necessary for creative innovation. In contrast, the more linear and rigid pedagogies associated with science and engineering education facilitate efficient learning of subjects such as those based on software packages, manufacturing and materials theory or mechanics. This paper describes the development of a project which aims to establish constructive links between the learning …
