Detailed Description

Describes small length flange issues found during sheet metal design analysis.

The flange length refers to the length of the flat section of a flanged edge. A small flange length issue can occur when the flange length is too small to accommodate the intended bend radius. This can cause the material to wrinkle or crack during the forming process, leading to a defective or unusable part.

Contains simple bend and it's flange that fails the following condition:

\[ \large L_f \geq T \times Rt + R_b \]

\[ \begin{aligned} & \small L_f - \text{actual flange length} \\ & \small T - \text{actual sheet thickness} \\ & \small Rt - \text{expected minimum flange length to sheet thickness ratio} \\ & \small R_b - \text{actual bend radius} \end{aligned} \]

Note

This issue can contain only SheetMetal_Bend objects and NOT SheetMetal_HemBend or SheetMetal_CurvedBend. Because small length flange analysis carried out only for simple bends (SheetMetal_Bend) and simple bends inside compound bends (SheetMetal_CompoundBend.FeatureList()).

Constructor & Destructor Documentation

DFMSheetMetal_SmallLengthFlangeIssue()

cadex.DFMSheetMetal_SmallLengthFlangeIssue.DFMSheetMetal_SmallLengthFlangeIssue ( cadex.MTKBase_CompositeFeature theFlange )

inline

Constructor.

Creates a small length flange issue from the MTKBase_CompositeFeature object. The first feature in MTKBase_CompositeFeature should be the flange bend (SheetMetal_Bend) and the second is an end flage face (ModelData.Face) as MTKBase_ShapeFeature object.
