02What is a JIG
What is a JIG?
A jig is a tool that holds a part in the same place with the same force. What varies slightly every time when set by hand, a jig makes identical every time.
01
Why it matters
01
Variation disappears
Results that differed by operator and by hour become the same.
02
Work gets faster
Setup time goes away, so more is made in the same hours.
03
Inspection becomes possible
A measurement is only trustworthy once the datum is fixed.

Jigs by process
- Assembly jig — CR #5A
Assembly jig
Holds parts in fixed positions so assembly variation disappears.
- Inspection jig — CR #5B
Inspection jig
Fixes the measuring datum so every part is measured under the same conditions.
- Cleaning jig — CR #5C
Cleaning jig
Holds parts so they neither move nor get damaged during cleaning.
