Detailed Description

Describes small diameter hole issues found during sheet metal design analysis.

Small hole diameter issue refers to the problem where holes with a diameter of less than required may cause deformation or cracking of the metal. This happens because the force required to create the hole exceeds the yield strength of the material, causing it to buckle or distort.

Contains simple hole that fails the following condition:

\[ \large Dia_h \geq T \times Rt \]

\[ \begin{aligned} & \small Dia_h - \text{actual hole diameter} \\ & \small T - \text{actual sheet thickness} \\ & \small Rt - \text{expected minimum hole diameter to sheet thickness ratio} \end{aligned} \]

Note: This issue can contain only SheetMetal_Hole objects and NOT SheetMetal_ComplexHole. Because small diameter hole analysis carried out only for simple holes (SheetMetal_Hole).

Member Function Documentation

◆ ActualDiameter()

double cadex::DFMSheetMetal_SmallDiameterHoleIssue::ActualDiameter ( ) const

Returns the actual hole diameter in mm .

See also: Hole()

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

◆ ExpectedMinDiameter()

double cadex::DFMSheetMetal_SmallDiameterHoleIssue::ExpectedMinDiameter ( ) const

Returns the expected minimum hole diameter in mm .

\[ \large Dia_e = T \times Rt \]

\[ \begin{aligned} & \small Dia_e - \text{expected minimum hole diameter} \\ & \small T - \text{actual sheet thickness} \\ & \small Rt - \text{expected minimum hole diameter to sheet thickness ratio} \end{aligned} \]
