- Jig may be defined as a work-holding device generally used in a drill press in conjunction with drill bushings for guiding the tools so that drills will produce holes only where the bushing is located in the drill jig.
- Jig may be also defined as a device used in mass production for increasing productivity by correct location & firmly holding the workpiece as well as guiding the cutting tool.
- Fixture may be defined as a device used to increase manufacturing efficiency and productivity in mass production.
- It locates the workpiece incorrect position and holds it firmly but it does not have provision for guiding the cutting tool.
- Set blocks and feeler or thickness gauges are used with fixtures to reference the cutter to the workpiece.
