Accomplishments from Previous Week

• • All components/parts/materials have been ordered

  • Manufacturing began/plate completed

  • Testing date and presentation date finalized with ATA

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

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

• • Belleville washers were too expensive, so we got wave springs instead (ATA said this was fine)

  • Discuss the analysis of the bolt shear/impact head

  • They were satisfied with the final design of all components

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

• • Show more calculations (which we have, we just did not put them in the presentation so that it would not be too long)

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

• • Some students were concerned with consistency of results after reassembly of the machine

    • Based on calculations/interchangeable impact heads/designated assembly holes (and each tube will be marked so that it will be put together exactly the same every time), we should have consistent results

Risks and Areas of Concern

• • Time crunch

    • We will have testing time on Monday, but more testing time is always desirable. Due to our manufacturing schedule + ATA's busy schedule, setting up an agreeing time is difficult

    • Machine shop hours are short and space is crowded

Resources or Information Required but not Available

• • All resources/info has been easily available thanks to ATA

Schedule

• • Complete ALL manufacturing by weekend

  • Do some dry runs of the completely manufactured machine over the weekend to prepare for testing on Monday with ATA

  • Update Gantt chart.

  • Prepare presentation for ATA for Friday 6/5

  • Do poster by this Friday

  • Work on report/webpage

Budget (list amount spent and amount remaining)

• • Spent $1881.43

  • Remaining $318.57

Progress on Report and Webpage

• • Will read student feedback on both report/webpage and make corrections we find helpful
