Answer:
Explanation:
The terms jigs and fixtures are used rather loosely in all modern industries. In the machine shop a jig is usually an appliance, which guides a cutting tool, while fixture is simply a device for holding the work. In the automotive industry a jig is a work holding device wherein all positions for assembly or fabrication operations are pre located, while a fixture is a work holding device which must be set in relation to the operating tools as part of the assembly or fabrication operations. In the aircraft industry the terms are synonymous and could be applied to virtually all special assembly tools.
In general a jig or a fixture is a tool whose structure is designed to hold or align component and/or tool in the manufacturing process of fabrication or assembly, so as to produce work that is interchangeable within the tolerances set by manufacturing requirements. The device may be adjustable or non adjustable, stationary or portable and it may have any of innumerable physical characteristics. The ease of removing the finished component and fixing new component should have to be given more importance in both jigs and fixtures.
