Why Inconsistent Parts Bring Down Automated Production Lines

Small differences in part dimensions and shape can cause automated production lines to stop frequently, misjudge good parts, or miss defective ones, because each station sets its path, fixtures, and force limits for a single nominal part. Differences such as stamping burrs, injection-molding flash, and machining dimensional drift accumulate; at Cp 1.00, about 0.27% of parts are out of tolerance, and at Cp 1.33 this falls to about 64 per million.
