MANUFACTURING PROCESSES & SPECIFICATIONS TERM PROJECT—FALL 1995
ENTC1120 – SP2018
Assignment #D2 – Design Update
The purpose of this education is to prepare for a professional career. Therefore, ALL assignments are expected to have a professional presentation. This major assignment provides an opportunity for students to explore common industrial manufacturing processes, and the engineering documentation necessary to support manufacturing.
Refer to the syllabus, the Tips for Professional Presentation, and the Scribbler’s note. (You may also find it helpful to refer to the department’s Language Skills Handbook, in particular the Written Reports page; http://www.etsu.edu/scitech/langskil/reports.htm.)
Students will provide an update for the design of the manufacturing process plan that was proposed in Assignment #D1.
The “design” in this project is the design of a manufacturing process. Products can be produced using different materials, and a variety of related processes. The manufacturing process is the result of the product and process design.
Students will evaluate a product’s design criteria, and will determine and document materials and methods to manufacture the product.
This design project shall:
1. Reinforce concepts such as Concurrent Engineering, Design For Manufacture (DFM) techniques, and engineering document preparation (drawings and reports).
2. Demonstrate students’ understanding of the various manufacturing production processes and how these processes impact design decisions and parameters.
3. Provide an opportunity for students to hone their communication skills by making technical drawings, reports, & presentations.
The goal of Assignment #D2 is to encourage students to work towards completion of the design of a manufacturing process.
This assignment will provide opportunity for students to improve their manufacturing plans. Students will receive feedback (with required improvements and additions), to be implemented in future assignments.
Each product must meet the following criteria:
1. Consist of at least three, separate manufactured parts (which may be assembled as desired). “Manufactured parts” are defined as parts which, for the purposes of this project, will not be available for purchase through an off site vendor; i.e.: the part must be designed & fabricated.
2. Use at least four of the six secondary processes (casting/molding, forming, separating, assembling, finishing, conditioning). Any one discrete, manufactured part can undergo four secondary processing steps and still meet the above requirement. However, the other, two discrete parts also have to be designed and manufactured using at least one secondary process.
The format of this assignment is a project (process) summary report, which is a technical document, containing particular sections. The following is a list of required items, to be included in the same order as provided.
Submit a product design package consisting of the following items:
1. Project Cover Letter – The cover letter could be similar to your project proposal in Assignment #D1 (with any improvements). The phrasing should be updated to reflect that the project is proceeding (as opposed to being proposed).
2. Cover Page – Product title, Doc. No. & Rev. Date, Name & Title
3. Table of Contents
4. Log of Revisions (typically blank for this assignment)
5. Applicable Engineering Reports (see below)
6. Applicable Engineering Drawings (see below)
NOTE: All engineering drawings and reports are to be referenced by a Document No., a Revision No., a Revision Date, Document Title, and (if applicable) ECOs.
7. Vendor specifications & literature (as appropriate).
8. Appendices (large charts, tables of supporting data, diagrams, etc.) (as appropriate).
9. References (as appropriate).
Engineering Reports to include, but not limited to, the following:
· Product Description and Specifications.
· The goal of this document is to show that the design criteria of the product have been considered. In other words, the product design was evaluated, and reasonable conclusions have been made regarding the performance and materials of manufacture.
· Identify the rigors to which the product will be subjected, and identify the design criteria.
· From the design criteria, determine and document the specifications.
· Once the specifications have been determined, select appropriate materials of construction.
· Manufacturing Process Plans
· Provide one Manufacturing Process Plan for the assembly, plus and additional Manufacturing Process Plan for one component part;
· Complete each Manufacturing Process Plan in full detail, including step number (order of operations), a description of the production operation, the tooling (fixturing, gauging, etc.) to be used, the required machine/equipment, and the specification to be achieved in each production step.
· A sample Manufacturing Process Plan is provided. More advanced formats are available – see “Control Plans”, “Quality Plans”.
· Installation, assembly, test, and inspection procedures and operations instructions (as appropriate).
Engineering Drawings to include, but not limited to, the following:
· Product Installation sketch or drawing (if applicable);
· Product Assembly drawing;
· For all drawings, use standard drawing conventions. For example, title blocks, full orthographic views and/or isometric views, proper dimensioning, etc.
The project is due by Sunday, March 25.
