Small louver depth DFM check
Small louver depth overview
Small depth of louvers in sheet metal can lead to limited airflow, reduced strength, clogging or blockage, and increased noise transmission. These factors can impact the effectiveness and efficiency of ventilation systems and the overall durability of the sheet metal structure.
Small louver depth detection conditions
MTK identifies this issue when the following condition is met:
where:
- — louver depth
- — actual sheet thickness
- — expected minimum louver depth to sheet thickness ratio
How MTK detects small louver depths
MTK automatically analyzes B-Rep CAD models for small louver depths. 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.
Documentation and API reference
Detailed API reference for the small louver depth DFM check is provided in the MTK documentation, including issue classes, detection interfaces, and integration details.
