Irregular extruded hole height DFM check

Irregular Depth Extruded Hole issue in sheet metal refers to a problem where the depth of an extruded hole is not consistent or uniform. This issue can bring about a weakened structure, compromised integrity, and difficulties in assembly.

Irregular extruded hole height detection conditions

MTK identifies this issue when either of the following conditions is met:

where:

• $Extr{H}_h$ — analyzed hole extrude height
• $T$ — thickness of analyzed sheet
• $Rt$ — minimum hole extruded height to sheet thickness ratio

or

where:

• $Extr{H}_h$ — analyzed hole extrude height
• $ID$ — analyzed hole inner diameter
• $Rt$ — maximum hole extrude height to inner diameter ratio

How MTK detects irregular extruded hole heights

MTK automatically analyzes B-Rep CAD models for irregular extruded hole heights. The SDK checks the relevant geometry against DFM criteria to identify potential issues that can increase manufacturing complexity or cost, or lead to quality or assembly problems.
