156B Week 4

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Designs have been adjusted for manufacture purpose, where different standards would be applied to the designs.

  • The analysis is being made based on high-quality 3D printing, and machined parts would be followed after.

Accomplishments from Previous Week

• • Improved design and added new concepts

  • Made decisions for the following manufacture and prototype process

  • Talk to Tom for design advice that would facilitate manufacture

  • Made high-quality 3D printing prototype

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• Analysis on CAD designs (All members)

• FEA design (William)

• Physical testing of 3D Printed Prototypes (All members)

• Applicable Standard report (All members)

• Finish 3D Printing

• Choose a design

• Start manufacturing

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • The sponsor expected some physical and on-scale prototypes for testing.(4/9/2018 from Dr. Lin)

    • Action: 3D print and machined parts are being made. 

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

• • More design concepts are needed, where blades are better constrained. (Also consider how things would be likely to fail.)  (4/11/2018 from Prof. Delson) 

    • Action: New design concepts and modifications are being made.

  • Expect to see the actual prototypes (4/18/2018 from Prof. Delson) 

    • Action:3D print and machined parts are being made. 

  • Give suggestions for the presentation (4/18/2018 from Prof. Delson) 

    • Action: Changes would be made for next presentation

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • Suggestions for the presentation would be taken for the next time.

    • Ex. Lengthy, Descriptive titles, Clearer presenting

Risks and Areas of Concern
