156B Week 8

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

• • The heat staking machine has been redesigned to provide better mounting methods for the linear actuator and prevent misalignment.

  • Fabrication has begun on the physical model of the machine and a majority will be finished by the end of the week. 

Accomplishments from Previous Week

• • Made final decision of which linear actuator to use.

  • Ordered mostly all parts required to construct physical model of machine.

  • Redesigned entire housing for the linear actuator and orientation of the machine components.

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

• • Finish assembling entire physical model of heat staking machine (all members).

  • Prepare preliminary design review presentation (all members).

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

• • A meeting with our sponsor, Kevin Kunicki was held on 5/19/2020 via Zoom. The comments were:

• 1. Call Progressive Automations for more information on control boxes that may be used with our linear actuator in the project.

  2. Between a linear actuator with higher speed and one with greater torque, the latter would be a better choice.

  3. Dynamic control can be achieved by controlling PWM.

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

• • A meeting with our instructor, Dr. Ghazinejad and our TA, Rishabh Khanna was held on 5/21/2020 via Zoom. The comments were:

• 1. Make captions for figures and tables in the report detailed enough so that the figure or table is self-explanatory.

  2. Consider using a thermistor instead of a thermocouple to measure the temperature of the heat stake.

  3. Allocate enough time to work on GD&T of machined parts for the entire project.

Risks and Areas of Concern

• • Our sponsor has subcontracted a manufacturing company to machine the required parts for our project but due to the COVID-19 pandemic, the lead time for those parts has extended from roughly 3 days to 2 weeks which means that we may not receive the machined components before the end of the quarter.

Resources or Information Required but not Available

• • None.

Schedule

• • The Gantt chart was last updated on 5/21/2020 and is currently up to date.

  • The upcoming goal set for 5/30/2020 is to troubleshoot any errors that may arise with the physical setup of the project.

Budget (list amount spent and amount remaining)

Remaining:

• • Equipment and parts: $1309.74

  • Machine shop expenses: $1500

Spent:

• • Equipment and parts: $690.86

  • Machine shop expenses: $0

Progress on Report and Webpage

• • Feedback from the instructor and TA have been provided for the report and revisions have been made for resubmission.

  • The website is now up to date.
