One method of reducing cost per component is to reduce machining cycle time. The manufacturing cycle time can be reduced by reducing nonproductive time like loading, unloading, and the placing of work piece onto the machine. Here jig and fixture design has important role to play. Productive time for a machine is the time required for by the machine.In short, the fixture is a tool that ensures correct and quick clamping (or loading) of the work piece with respect to the machine tool.For example, you have a drill machine and want to make a 10mm diameter hole at the point of intersection of the two diagonals of a square plate. The hole should be inclined at 45 degree angle with the surface. Now you have two choices, either you clamp the work piece with the vice or use a arrangement like below.
The above arrangement is a simple drilling fixture.
