P09701: Corning Tropel LightGage Metrology System/public/
Week 3 (by Friday 3/27/09)All documents generated by the P09701 team during Week 3 of MSD2 are to be posted here.
MSD2 Week 3 Status Update
1. Drawings updated.
- The CAD files the team created in Pro/E student edition are not compatible with the standard Pro/E program--thus, Jack Frankovich at Tropel had to re-model all of our parts so they could be officially uploaded to Tropel's database.
- Some changes were made to the parts for better manufacturability. We were able to re-use some parts in the assembly, reducing the number of unique parts and part numbers. This significantly simplified manufacturing and bookkeeping. This also reduced the complexity of the whole assembly.
- Drawings have been re-drawn and uploaded to Tropel's Winchill server.
- Drawings have been submitted to machine shop (albeit late due to compatibility issues). The due date for these parts is set for 4/15 at the latest.
2. Tropel Shutdown Scheduled.
- It has been announced that Tropel will be shutting down for 2 weeks in April (due to economic factors). Thus, if the parts are not completed by then, we will lose another 2 weeks of build time. This is a large risk, but Tropel's machine shop is known for completing their work on time.
3. The Granite.
- It is looking increasingly unlikely that we are going to be able to get the steel TMC table and legs to RIT and a 10" hole drilled through it. We cannot get help from Tropel maintenance as it is not associated with any Tropel project, and we have no means of transport to RIT. Thus, it is looking like we may have to settle for plan B.
- Plan B: A scenario that is looking increasingly likely is that we do all our assembly at Tropel. Tropel is going to be building a LightGage demo unit using the granite that was previously assigned to this project. The team is requesting a week of time where we can assemble the project, test it, and document it. Once we prove that the concept works and document it, we will take it apart and let Tropel use the granite for their demo unit. Standby for more details...
4. Parts Have Arrived!
- All COTS parts that have been ordered have been received.
- A thru beam and mount have been acquired from Tropel for this project.
5. The Keyence Sensor Works!
- Ben has successfully tested the Keyence sensor--it works just as planned. It will cut power to the actuators as soon as the beam is broken. See schematic in Week 1:Parts Ordering.
