The primary function of a bushing in relation to a jig is to provide cutting tool guidance. Bushings are cylindrical components that fit into jigs and act as precise guides for cutting tools, ensuring accurate alignment and positioning during machining operations. This is essential for maintaining tolerances and achieving the desired finish on the workpiece.

Bushings are typically made from materials that can withstand wear, allowing them to guide the tools without degrading over time. By using bushings, assembly mechanics can minimize play and improve the precision of the cutting process, which is crucial for maintaining the integrity of aerospace components.

This function differentiates bushings from other elements such as fastener security or holding a piece in place, which may involve different mechanical components or features. The specificity and accuracy of a bushing's role in guiding tools highlight its critical importance in optimizing the performance of jigs in manufacturing processes.
