Build & Test Prep
Introduction to MSD II
In the time we have before Imagine RIT, our team needs to have our final product assembled and have experimental evidence that it will meet our requirements. This starts with machining and receiving components, and assembling subsystems for testing and validation. This leads to system assembly and testing and the creation of final documentation.
Things We Had Left Over from MSD I
At the end of the fall semester, our team had some issues in our part drawings to be machined by Morgood Tools, our planned layout of electrical components, BOM and schedule for this spring semester. These issues have been addressed for this review.
Items that needed significantly more work (Red Light):
- GUI - Do a test right when we get back (once we have the DAQ)
- Electronics Box - Needs a design (assembly and drawing)
Items that needed more work (Yellow light):
- Drawing Package - Drawings need to be dimensioned to datums based on importance for the engineer (not the machinist). Once completed talk to Mike to verify everything is ok. Then, talk to Morgood to make sure they know what we want and to get another quote. Make sure the new quote isn’t too expensive (Update risks)
- Risks - If quotes come back significantly higher, ask Morgood where we could cut some costs, what is costing us more money (could catch them in a lie). Look for suggestions from Mike to cut costs
Items that are completed (Green Light):
- System Design - Overall a good design that should accomplish the task
- Electronics - All electrical components have been verified by Professor Wellin that they should work in the current system
- Test Plans - Perhaps take a look at Mil Handbook 51 (essentially statistics for dummies)
Things We Wanted to Accomplish This Phase
- Finish drawings and get approval from Mike
- Start working on in-house parts
- Visit Morgood and talk about our products we are outsourcing to them
- Get approval from Mike regarding our drawings
- Ask Mike to order the load cell and conditioner for us
- Plan layout of electrical components
- Finish BOM and semester plan
What We Did
Team Catch Up and Realize What Needs to Get Done (MSD I Post-Mortem)
- Discussed remaining items from MSD I and ensured they had been completed
- Prioritized machining and discussions with Morgood
- Placed orders for remaining components
- Drawings for Morgood
- These drawings were approved by Mike and purchase orders have been filled out and submitted
- Because we have so many custom parts, we went to the machine shop day one to get a quick start on our parts.
- Machine shop is slow right now and offered to make a few of them for us. They will be making the Load Cell Block, Retainer, Pivot Block and Encoder Pin
- We are currently working on the slides
- We have milled both outer slides and inner slides to proper length
- We still need to make the cutouts on the slides

Test Plan Summary
- Test Plans
- Some of these tests are of components, and others of subsystems and systems. We will test progressively more complex requirements throughout the semester so that components of each test have been previously validated.
- This spreads the test out through the semester, so we won't have to test everything in the same phase.

Risk and Problem Tracking
- New risks: Rob in the machine shop claims that using aluminum for the slides might hurt us, he suggested using steel.
- Ways to fix new risks: We grabbed a few pieces of steel from the scrap rack to avoid paying for new pieces if we need to redo the slides.
- Risk Management
- Problem Solving
Plans for next phase
- Finish Slides and other in-house machining
- Receive all components other than Morgood parts
- Make any modifications needed to electronics enclosure
- Perform component-level tests
- Getting to the machine shop early paid off. They've offered to help us out quite a bit.
