Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Risk Reduction test has been modified and completed.
Modified because of lack of access to a measurement device that can measure the height of the flash
Using spring displacement sensors did not work because contact with the flash leads to the flash being affected
It was determined that a non-contact profilometer may be the best method to measure the irregularities of the dimple
Designs have been considered:
Creating a custom dremel bit
Using a CNC mill machine to polish dimple
Using CNC lathe to cut flash off of dimple
Emailed Keysence and Gelsite regarding their profilometers
Theya re priced at $50,000
Accomplishments from Previous Week
Risk Reduction Test has been modified and completed.
Test is focused on determining the surface area of impact of each of the dremel bits and end mills.
Additionally, test is determining whether the chosen bits can reduce the flash.
Lessons from Risk Reduction
may need to order a custom bit in order to fit the hexagon format and curved surface of the dimple.
Individual component analysis has been completed
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Design and order a custom dremel bit (Aaron)
Research measurement techniques to determine the efficacy of the flash removal systems are designed (Woo Jae)
Order parts that may be needed (Marshall)
Brainstorm complete systems that may be used (Rohan & Jacen)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Sponsor has agreed to give us CAD of pins used for injection molding (email 3/20/19)
Sponsor needs a legal patent document to be signed (email 3/20/19)
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Professor Gravish approved the new risk reduction test after it was discovered that measuring the flash is extremely difficult with available measuring devices (in person 3/14/19)
New risk reduction test was created and implemented
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
James (TA) mentioned that labs on campus may have a item that would suit our needs (in person 4/13/19)
Nano3 lab has a profilometer that would suit the measurement needs of this project
In the process of applying to use this machine
Risks and Areas of Concern
Will a adequate measurement device be found to determine efficacy of the system?
Will the system be precise enough to be able to position the head to remove the flash?
Will the system be able to rotate the ball to the correct orientation?
Resources or Information Required but not Available
Need a measurement device that can precisely model the flash on a dimple.
