  • PLC control related parts and valves ordered.

  • Finalized the shape of the block cutter.

Accomplishments from Previous Week

• • Finalized the exact order of the frame parts and the pneumatic thrusts with the sales. (Keyu/Rui)

  • Finished submitting the two orders. (Keyu)

  • Finalized the CAD file integrating the frames and the cutters. (Keyu/Insik/Alonso/Rui)

  • Stress Analysis of the frames. (Insik)

  • CAD animations for the full motion of the machine. (Alonso)

  • Discussed the customization of the stainless steel cutter with the machine shop. (Insik)

  • Report writing - applicable standards. (Keyu)

  • Designed the shape of the cutting blade. (Rui/Alonso)

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

• • Start assembly of the frame once receive the frames. (Keyu/Insik/Alonso/Rui)

  • PLC programming with the given software(Automation Organizer). (Keyu/Insik/Alonso/Rui)

  • Follow up with the machine shop on cutting the blocks. (Insik/Keyu)

  • Test the pneumatic thrusts with different air pressure. (Keyu/Insik/Alonso/Rui)

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

• • How well does the pneumatic slider last at a dusty environment? Does it need regular cleaning? (In person)

  • Make sure the cutter should be easy to maintain and to be changed. (In person)

  • Make sure the flash will fall towards certain direction after being trimmed. (In person)

  • Estimate the entire processing time. (In person)

  • Problem of accessing the project page resolved. (Email)

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

• • Cutter designed to be 45 degree angle for the ease of cutting. (In person)

  • Top cutter - three pieces/one single piece. For the ease of assemble, one single piece was chosen. (In person)

  • Safety issue - door switch for closing and opening the circuit running the entire system. (In person)

  • Make sure the pneumatic slider would not fall without power - addressed this concern to the machine automation engineer, necessary parts are provided. (In person)

  • Using heat gun to heat up the flash in order to assimilate the actual temperature. (In person)

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 small thickness.

  • Accommodate different geometries.

Resources or Information Required but not Available
