Overview of Status of Analysis, Design, Fabrication, Tests, etc.
The current model of the machine resides with a team member at their residence due to the closing of the workspace in EBUII - 338.
The major components of the final design for the machine have been decided and will be modeled soon.
Accomplishments from Previous Week
Redefined scope of project based on what team would be able to accomplish under new circumstances.
Narrowed down 4 main tasks to tackle.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Decide which linear slider to purchase. (all members)
Finish background, review of existing solutions, statement of requirements, deliverables, title page, and appendix with individual component analyses of report. (Barbara)
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 4/3/2020 via Zoom. The comments were:
Implement 3 sensors into final design- one to check if set base is there, one to check if set base is aligned properly, and an operator sensor or mechanical stop to safely stop the machine to prevent accidents.
Split the project into separate parts and have each inidividual team member tackle their respective part remotely. All members can come together to assemble the final product if desired.
Use a data logger to check the effectiveness of the thermocouple that is to be implemented for checking the temperature of the horns.
Product quality and operator safety are two main goals.
Find a way to fix the whole upper portion of the machine so that it will not rotate while operating.
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 one of our sponsors, Dave Gillet was held on 4/2/2020 via Zoom. The comments were:
Think about how to redefine scope of project and what resources (machine shop services, 3D printing, etc.) may be needed and when.
Operator safety is one of the main priorities and this may be achieved through implementing physical buttons, a touchpad, a control package, or Arduino.
Generating a block diagram of all the separate components of the assembly is a must.
Consider using two linear slides- one for capturing and fixing plastic disks and another for moving the base plate into the brass horns.
Begin writing report and assembling first presentation.
Risks and Areas of Concern
Using a vertical linear slide for the base plate will be cheaper but additional hardware must be implemented so that the web can be detached from the base plate after each assembly. The team is concerned that the design for the web detachment may not be achieved in time.
Using a horizontal linear slide for the upper portion of the assembly will resolve the issue above but a linear slide that can withstand 90 pounds of force must be purchased and most slides in that have this capability are extremely expensive (half or more of our total budget).
Schedule
The Gantt chart was last updated on 4/3/2020 and is currently up to date.
The upcoming tasks set to begin on 4/6/2020 are to purchase a data logger for the thermocouple and to redesign the horn and aluminum plate attachment.
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.
