1. Jigs and Fixtures Increased Consistency and Efficiency

2. What is a Jig -Typically a simple movable device to increase accuracy. -Used to increase productivity. -Allows a variety of tools to be used. -Adjusts for various tools instead of purchasing new tools.

3. Why use a Jig?  Useful when making multiple parts or repeating a pattern.  Jigs let you speed up your work.  You don't have to individually adjust every piece you are cutting, sanding, bending, forming, etc.

4. Jig Example

5. Fixtures  More of a permanent tool that is used for assembly purposes.  Typically does not have as much flexibility as a jig.  Most likely used for high volume production.  Made of durable materials such as tool steel, iron, aluminum alloys, etc.

7. Other Fixture Examples  Used most commonly for welding and metal assembly work.  Typically used for products that must be very precise.  Sometimes are exposed to high temperatures and stresses

8. Question  Is it necessary to still measure and check your design after fabrication? Why?
