Fixture

How it is used

Used in tooling design and production. A fixture has locating pins, clamps and sensors that confirm the part is present. You load, clamp and unload a part. Strictly, a jig also guides a tool, but in daily use the two words are often mixed.

Example sentences

1. The fixture didn't clamp because the part wasn't sitting on the locating pins.

2. We need two fixtures on a turntable so the operator can load one while the robot welds the other.
