Overview of Status of Analysis, Design, Fabrication, Tests, etc.
The current model of the machine has been assembled and set up in EBUII - 338.
A linear slider with a stepper motor has been placed within the main assembly to test whether or not this will fix the alignment issue but the team has struggled to properly power the motor.
Accomplishments from Previous Week
Risks were identified and methods to tackle them were ideated. These were then presented to the class.
Milestones were set out and a detailed schedule for next quarter was created.
Individual component analyses were completed and presented.
A sprocket was designed and modeled in Solidworks and made ready for manufacturing.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Decide on a linear slider to purchase and make a transaction (Gerui).
Continue research on individual components but with consideration of sponsor's comments. Decide on final components to use in final design (Matt, Gerui, Barbara, Hugo).
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
A conference call was held with the sponsor on 3/18/2020.
In this meeting, the following comments were made:
Xometry was recommended as a possible manufacturing service in the case that we are unable to use the machine shop due to current events.
A change in material for the brass stamp piece is recommended. Bronze or copper were suggested as possible candidates.
The idea of implementing a pneumatic cylinder is welcome but a heat-resistant cylinder must be considered since it will be operating within or close to the heating element.
A de-reeling mechanism should be implemented using the parts from the current de-reeling device.
Manuals for the heat staking and de-reeling devices will be emailed to team by sponsor shortly.
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 David Gillett, the VP of operations at Capillary Biomedical and an instructor, was held on 3/12/2020. The comments were:
Figure out a way to load web, locate post, and disconnect.
Look into web-based automation.
Aligning the holes in the adhesive and the hole in the plastic disk are not our concern as this will be a 6 month project.
Figure out way to find sprocket holes, maybe through automation.
Consider diameter and curve of sprocket when designing.
An additional meeting was held with our current instructor, Dr. Tustaniwskyj, on 3/12/2020.
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Students who watched our risk reduction presentation generally agreed that line drawings or CAD models of designs under consideration should be completed instead of just having hand drawings. These comments were made on 3/17/2020 through anonymous feedback forms.
Risks and Areas of Concern
After automating each individual component, how will we incorporate all these processes into one main assembly?
How many automation procedures can be accomplished in 10 weeks?
Resources or Information Required but not Available
Machine shop availability for next quarter, if it will open.
Schedule
The Gantt chart was last updated on 3/15/2020 and is currently up to date.
The upcoming goal set for 3/20/2020 is to purchase a linear slider so that we can achieve our first milestone of implementing a linear slider to align the brass stamp with the plastic disks.
Budget (list amount spent and amount remaining)
Remaining:
Equipment and parts: $2000
Machine shop expenses: $1500
Spent:
Equipment and parts: $0
Machine shop expenses: $0
Progress on Report and Webpage
The webpage is up to date for the home, reports, team, and internal sections. The other sections are currently not applicable.
The report section contains our individual component analyses and risk reduction presentation.
