[Pansophy] SNS PPU inspection traveler breakdown structure

Hi Gary
The reason for my suggestion is that I understand Survey & Alignment are actually doing the dimensional inspection because the end cans are too big to fit on the CMM. So a thought was to have all the dimensional inspections together for the end cans
I realize that normally Survey & Alignment are doing other types of measurements that definitely fit in the CAM traveler such as alignment checks etc.
So if it preferred to put the End Can dimensional work into the CMA traveler I would be fine with this also – the main thing is for the data to be easy to find down the road
Thanks Anne

Hi Valerie & Anne,
I decide to comply with the new policy and have split my SEC traveler into 3 according to what Valerie suggested. Now there is SNSPPU-CWI-SENC, SNSPPU-INSP-SENC and SNSPPU-CMA-SENC-INSP for inspection of PPU SEC. Pansophy team doesn't need to write the CWI-SENC traveler. There will be 3 such inspection travelers for the REC as well.
I noticed that "Anne’s group with outreach to Survey & Alignment group". Normally, it is the CMA group who coordinates with S&A to conduct dimensional measurements that CMM/SRF QC cannot do. Should we maintain this tradition? After all, CMM/SRF QC is short of hands and data acquired by S&A are usually useful information for CMA.
If you wish, I can split the dimensions for S&A from those that CMM/SRF QC can measure then feed them into the SNSPPU-INSP-SENC and SNSPPU-CMA-SENC-INSP, respectively. That way, CMM measures what CMM can and CMA will work with S&A to get other dimensions taken. It means more work for me, but I think this approach will help to keep the convention.
Thanks,
Gary

Gary,
Creating just one traveler for each part is not advisable. It does not comply with current Traveler work center breakdowns which support our Reporting system. It also does not support our attempt to be more ISO compliant in being able to track parts, work done and timelines. It causes confusion as to which work center or person is responsible for closing a traveler and ensuring all data is entered appropriately. It also helps maintains NCR continuity to part, problem and location.
We would appreciate if you could help us maintain this quality system.
We propose the following:
Pansophy Team will Create Travelers:
1. SNSPPU-INV-SENC: Inventory Traveler (Phil’s group with upload of shipping documentation)
2. SNSPPU-CWI-SENC: CWI (Jenord’Ss traveler)
Travelers you would need to write:
3. SNSPPU-INSP-SENC: Visual and Dimensional Inspection Traveler (Anne’s group with outreach to Survey & Alignment group) SNSPPU-INSP-SENC
4. SNSPPU-CMA-SENC-INSP: All other work which is done in the Cryomodule Assembly Area (Fischer’s group and groups he coordinates with)
1.The only change would be if Larry King wants a separate traveler for his team’s electrical checks, but we do not require this.
This would result in you writing 2 travelers (INSP and CMA) for each of the SENC and RENC. I hope you will find this acceptable and if you need help, please ask.

Mike,
Yes. Unless I am forced to write 6 travelers per end can or a total of 12 travelers for the SEC and REC. I don't see much technical merit in writing 12 travelers for a set of end cans.

Gary,
Are you planning to write just 1 INSP traveler for the SEC and 1 for the REC?

I think I am fine with making one traveler for SEC and one for the REC.

That sounds reasonable to me. Just FYI, I have put the weld documents into the weld spec on my parts, and then uploaded all of them into the INV traveler, but use your judgment - probably you have more documents.

Thanks Katherine.
Using SEC as an example, I would need to write the following travelers:
1. Visual inspection traveler --- for SRF QC group, i.e. Anne's group
2. Dimensional inspection traveler --- for Survey & Alignment group, end cans won't fit into our CMM machine
3. Weld inspection traveler --- for CWI
4. Instrumentation electrical checkout --- For Larry King's group
5. Vendor docs check --- for SOTR, CWI and leak check specialist
6. Pressure test and leak check --- For CMA
That's a lot to write for just the SEC. Then for the REC, I would need to write another 6 travelers...I don't think that's really what we want. But if PPU management prefers to have such a breakdown structure, I will write 12 travelers for the SEC and REC...someone please let me know.

The idea is to break the travelers down by workstation, so one person is responsible for the part as long as it is being inspected under that traveler.
We are trying to minimize travelers that stay open for months while working through the inspection process, and also reduce misplaced or damaged parts as they are passed from one workstation to another, so please let that be your guide as you decide how to separate the travelers.
I think you will just have to use some judgment about what seems like a sensible way to separate travelers. Maybe Anne has further suggestions.
Regards,
Katherine

Any advice?

Ed & Naeem,
It's unclear to me if there is a consensus on how many breakdown travelers that PPU project wants to have for a certain assembly to be inspected. I hope that you can clarify what you want all SOTRs to prepare.
The usual receiving inspection steps that I can think of are:
shipping crate condition check --- this would be in INV
vendor documents check --- docs upload to INV. SOTR as well as SMEs need to check them for completeness and correctness
visual inspection --- SRF QC or CMA
dimensional inspection --- may be done by SRF QC folks or Survey & Alignment folks
instrumentation electrical check out --- Larry's group
fit-up test --- mostly done CMA
weld inspection --- by weld examiner or CWI
cold shock --- CMA
pressure test --- CMA
leak check --- CMA
repackage
Please advise. I am about to convert Ed's SNS end can travelers to the new format and need to know how many travelers that I need to write for Supply & Return End Cans.
Thanks,
Gary
