Jigs and Fixtures Increased Consistency and Efficiency
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.
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.
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.
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
Question • Is it necessary to still measure and check your design after fabrication? Why?
