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 ( const MTKBase_CompositeFeature & theFlange )

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.

Member Function Documentation

◆ ActualLength()

double cadex::DFMSheetMetal_SmallLengthFlangeIssue::ActualLength ( ) const

Returns the actual flange length in mm .

See also: SetActualLength()

Examples: MTKConverter/Program.cs, and sheet_metal/dfm_analyzer/Program.cs.

◆ ExpectedMinLength()

double cadex::DFMSheetMetal_SmallLengthFlangeIssue::ExpectedMinLength ( ) const

Returns the expected minimum flange length in mm .

See also: ExpectedMinLengthToSheetThicknessRatio(), ActualSheetThickness(), Bend()

Examples: MTKConverter/Program.cs, and sheet_metal/dfm_analyzer/Program.cs.

◆ ExpectedMinLengthToSheetThicknessRatio()

double cadex::DFMSheetMetal_SmallLengthFlangeIssue::ExpectedMinLengthToSheetThicknessRatio ( ) const

Returns the expected minimum flange length to thickness ratio.

\[ \large L_e = T \times Rt + R_b \]

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

◆ Flange()

const MTKBase_CompositeFeature & cadex::DFMSheetMetal_SmallLengthFlangeIssue::Flange ( ) const

Returns the problematic flange. The first feature in MTKBase_CompositeFeature is a flange bend (SheetMetal_Bend) and the second is an end flage face (ModelData::Face) as MTKBase_ShapeFeature object.

See also: SetFlange(), MTKBase_CompositeFeature

Examples: MTKConverter/Program.cs, and MTKConverter/main.cxx.

◆ SetActualLength()

void cadex::DFMSheetMetal_SmallLengthFlangeIssue::SetActualLength ( double theLength ) const

Sets the actual flange length in mm. theLength should be greater than zero.

See also: ActualLength()

◆ SetExpectedMinLengthToSheetThicknessRatio()

void cadex::DFMSheetMetal_SmallLengthFlangeIssue::SetExpectedMinLengthToSheetThicknessRatio ( double theRatio )

Sets the expected minimum flange length to thickness ratio. theRatio should be greater than zero.

See also: ExpectedMinLengthToSheetThicknessRatio()

◆ SetFlange()

void cadex::DFMSheetMetal_SmallLengthFlangeIssue::SetFlange ( const MTKBase_CompositeFeature & theFlange )

Sets the problematic flange 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.
