156B Week 6

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

• • Will receive all parts this week. (PLC controls, Aluminum frames, Pneumatic actuators)

  • Sent all parts(clamps, cutters, etc.) that need to be fabricated to the machine shop.

  • Start the assembly and the test of the actuators once receive the parts.

  • Will begin the PLC programs for the system.

Accomplishments from Previous Week

• • Discussion on how to make the fabricated parts with Tom. (Keyu/Rui/Insik/Alonso)

  • Finalized the CAD files of the fabricated parts. (Alonso)

  • Webpage - Final Design/Home. (Keyu)

  • Webpage - Pictures/CAD. (Alonso)

  • Report Writing. (Keyu/Rui/Insik/Alonso)

  • Force and material analysis. (Rui)

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

• • Finish the whole assembly for the main frame. (Keyu/Rui/Insik/Alonso)

  • Start programing for the PLC controls on WindLDR. (Alonso,Insik)

  • Report follow-up. (Keyu/Rui/Insik/Alonso)

• Finish the new design(Shrinking problem) for the bottom cutter with the spring mechanism. (Keyu/Rui/Insik/Alonso)

  • Finish most of the fabricated parts, at least clamps and front cutter. (Keyu/Rui/Insik/Alonso)

  • Communicate with manufacturers about the part adjust the horizontal posiontion for bottom cutters. (Keyu/Rui)

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

• • Did not meet sponsor due to lack of progress.

  • Informed them that the spring mechanism will be used to solve the shrinking problem. 

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

• • Need to improve the force and material analysis. (Inperson)

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

• • N/A

Risks and Areas of Concern

• • The cutter may not align with the edge of the flash - the container may be damaged while cutting.

  • Reliability and maintain of the top cutting blade - long blade with a small thickness.

  • Accommodate different geometries.

  • Bottom shrinking problem. 

Resources or Information Required but not Available
