Detailed Description

Describes a sheet metal Hem bend feature.

Hem bend is a result of hemming process in which a sheet metal edge is folded back on itself.

Hem bend

Hem Bend types

MTK supports hem bend types (defined by the SheetMetal_HemBendType enumeration) defined in the following table:

Flattened hem bend	The part of the edge that bends sits completely flush over the rest of the metal sheet. The angle between the returning flange and the sheet metal is 180 degrees.
Open hem bend	The returning flange is folded over the sheet metal but there remains an air pocket between the two. The bend angle is 180 degrees.
Teardrop hem bend	The returning flange is bent beyond 180 degrees. The resulting shape resembles a teardrop.
Rope hem bend	The returning flange at a bent of more than 180 degrees. Once the hem achieves the shape of an open hem, the returning flange is pressed onto the part surface through a flattening die.
Rolled hem bend	The bent portion of the sheet metal is tucked back into itself. This creates smooth round edges all around for holding the part from the hemmed edges.
