Joggle definition sheet metal.

Sheet metal stretches when it bends is an oversimplification. A small offset near the edge of a piece of sheet metal. A joggle often found at the intersection of stringers and formers is the offset formed on a part to allow clearance for a sheet or another mating part. Use of the joggle maintains the smooth surface of a joint or splice.

Often these bends are in opposite directions and less than 90. It allows one sheet of metal to overlap another sheet while maintaining a flush surface. A joggle bend in sheet metal and a joggling tool joggling 5 also known as joggle bending is an offset bending process in which the two opposite bends are each less than 90 see following section for how bend angle is measured and are separated by a neutral web so that the offset in the usual case where the opposite bends are equal in angle is less than 5 workpiece thicknesses. A surfacic flange or a web to be locally deformed.

Joggle presses can form multiple bends on sheet metal at the same time. Upon close examination of the bends we find that the sheet metal stretches on the outer surface and that the inside surface seems to shrink. This process is very useful in the formation of aerospace parts such as stiffeners ribs firewall assemblies webs formers covers and more. Joggle plural joggles engineering a step formed in material by two adjacent reverse bends.

A joggle is a feature which causes the main feature i e. A joggle die is optimized for one material and one thickness and temper. Have your folks make an exemplar of the die s product using the correct material measure it and make a standard detail drawing of the exemplar and a superimposed layer or sheet showing how the finished features relate to the dimensions of the actual die. Mild steel zintec galvanised steel aluminium alloys stainless alloys brass and copper.

Architecture a notch or tooth in the joining surface of any piece of building material to prevent slipping. A joggle joint weld is regarded as a special type of butt weld an overlap adhesive joint including mutually overlapping first and second plate parts 5 7 particularly sheet metal parts and especially vehicle body panel parts and an intermediate adhesive layer 9 the joint preferably being a joggled joint. The joggle is a feature which cannot exist alone.
