External edge fillet DFM check
External edge fillet overview
When designing external edges in CNC machining milling, filleting can pose some issues that need to be considered. Filleting the external edge can potentially lead to stress concentration points due to the bend of the fillet, leading to weak and broken corners.
The production of fillets on the external edge also requires special tooling and milling techniques that are expensive compared to other machining methods, e.g. chamfering.
Chamfers are preferable compared to fillets on the external edge in CNC machining milling design due to their ability to reduce stress concentrations, provide better clearance, reduce manufacturing costs, and improve overall appearance.
How MTK detects external edge fillets
MTK automatically analyzes B-Rep CAD models for external edge fillets. 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 external edge fillet DFM check is provided in the MTK documentation, including issue classes, detection interfaces, and integration details.
