No, not at the in-process operation. The question is: do I need to perform a delta FAI on that characteristic at final inspection because there was a CNC program change that can potentially affect FFF? How do you determine if the change really affects FFF when you are not changing any design characteristics?

Quote:
"4.6 Partial or Re-accomplishment of First Article Inspection
a. The FAI requirement, once invoked, shall continue to apply even after initial compliance.
b. The FAI requirements may be satisfied by a partial FAI that addresses only the changes from a baseline part number provided all other characteristics were conforming on the previous FAI and are produced by the original production processes.
c. When a partial FAI is performed, the organization shall, as a minimum, complete the affected fields in the FAI forms.
d. When the organization performs a partial FAI, the organization shall record the “Baseline Part Number”, including the revision level and reason for the partial FAI on Form 1 (see field 14).
e. FAI requirements may be satisfied by a previously approved FAI performed on identical characteristics of similar parts produced by identical means. When FAI requirements (partial or full) are satisfied in this manner, identify the “Baseline Part Number” on Form 1 (see field 14).
f. The organization shall perform a full FAI or a partial FAI for affected characteristics, when any of the following occurs:
A change in the design characteristics affecting fit, form, or function of the part.
2. A change in manufacturing source(s), process(es), inspection method(s), location of manufacture, tooling, or materials that can potentially affect fit, form, or function.
3. A change in numerical control program or translation to another media that can potentially affect fit, form, or function.
4. A natural or man-made event, which may adversely affect the manufacturing process.
5. An implementation of corrective action required to complete a previous FAI, as described in 4.4.
6. A lapse in production for two years shall require an update for any characteristics that may be impacted by the inactivity. This lapse is from the completion of last production operation to the actual restart of production."
So to answer your question - if a repaired was done to the part because it did not meet BP or customer requirements - yes a Delta is required.
When and where you do it is irrelevant as long as it is done. You could do it on the machine, constraint condition, in-process or at final - but it must be done and other affected areas.
