Irregular screw boss core diameter DFM check

The irregular screw boss core hole diameter issue refers to a situation where the screw boss core hole diameter is too big or small compared to the outer diameter. Proper diameter value is required to mitigate potential stress failures or flow issues caused by thick regions.

Irregular screw boss core diameter detection conditions

MTK identifies this issue when the following condition is met:

where:

• $D_h$ — analyzed boss core hole diameter
• $D_b$ — analyzed boss outer diameter
• $R_{min}$ — minimum boss core hole to outer diameter ratio
• $R_{max}$ — maximum boss core hole to outer diameter ratio

How MTK detects irregular screw boss core diameters

MTK automatically analyzes B-Rep CAD models for irregular screw boss core diameters. 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.
