The improved concept keeps the formed tube stationary in a P/N-specific zero-point nest. A common multi-axis measurement and trimming head approaches both ends, measures the actual tube condition relative to the fixture coordinate system, calculates the released cut plane and trims without re-clamping the part.
Seat approved tube sections on replaceable non-marking blocks. Do not pull the whole tube into nominal shape.
Clamps hold the seated tube only; they are not used as measurement datums.
Probe or laser-scan a short straight section and the raw end face to establish actual position and direction.
Compare the measured condition with the approved final geometry and calculate the material to remove.
Align normal to the measured local axis and trim End A, then End B, using one flexible machine platform.
Re-measure the finished end, apply PASS / HOLD logic and save the traceability record.
