A fixture generally comprises positioning elements (determining the correct position of a workpiece in a fixture), clamping devices, tool alignment guide elements (determining the relative position of a tool and a workpiece or guiding the direction of a tool), indexing devices (allowing a workpiece to complete several processing steps in one installation), connecting elements, and fixture bodies (fixture bases).
