What is the purpose of a joggle in metalworking?

In metalworking, a joggle serves a specific functional purpose by creating a step or offset in the material. This modification allows for clearance between a sheet and another mating part, which is essential in various assembly situations to ensure proper fit and function. For example, when two components are joined, a joggle can help accommodate variations in thickness or ensure that fasteners can be installed without conflict.

This feature can be crucial in maintaining the integrity of the structure by allowing for thermal expansion, vibration, or other movements that may occur during operation. While factors like aesthetics, structural reinforcement, or overall weight reduction can be relevant in design considerations, the primary intent of a joggle is to facilitate a precise and functional fit between components.
