I found the old straightening note tucked behind the drawing for our proposed FR5 bracket fixture. Then noticed the sample numbers on it belong to an earlier bracket revision. The current folder has restrained checks and final passes, but no measurements between release and correction. Which comparison should we make before this becomes the new operator's mystery job?
Start with what changed between revisions. On another bracket review here the contact face was the important question. Keep that old note identified, but don't assume it describes the current parts.
Then you cannot use the old correction time as a measured allowance for F. It still tells you to ask about extra work. Find the current process route before buying a new gauge to explain an old one.
Could the person doing the correction identify which brackets they handle now? That might connect the route sheet to the work without guessing from the folder order.
Aaron, the operator confirms current F brackets reach their bench, but only some. Liam, the estimate includes no correction. We need paired before-and-after measurements, not the old average.
Keep incoming fit-up in that paired study too. Otherwise you learn which F brackets need correction without learning whether they started from comparable parts and seating.
Amy, yes, and record the measurement supports. I have seen an attractive before-and-after chart compare a bracket held flat in a fixture with one standing free. It answered less than the caption promised.
I would ask fabrication and quality together, Liam. The person estimating needs their process decision, not just an instruction to make the number smaller.
Fabrication and quality now own the current-revision study. Estimator has added a provisional correction allowance rather than borrowing the old measured time. Thanks Amy; checking revisions stopped us starting with the wrong samples.
Keep that provisional wording when the estimate travels. Someone reading only the total should not be told the correction operation has already been characterised.
