Irregular notch corner fillet radius DFM check
Irregular notch corner fillet radius overview
If the ratio of the notch corner fillet radius to the thickness of the sheet metal is irregular, this can lead to problems in the production of notches.
Straight corners of the notch can be difficult to shear cleanly without causing deformation or fractures in the material. Rounded corners help distribute cutting force more evenly, reducing the chance of warping or breaking and providing a cleaner, more precise cut.
Irregular notch corner fillet radius detection conditions
MTK identifies this issue when the following condition is not met:
where:
- — actual notch corner fillet radius
- — actual sheet thickness
- — expected notch corner fillet radius to sheet thickness ratio
How MTK detects irregular notch corner fillet radii
MTK automatically analyzes B-Rep CAD models for irregular notch corner fillet radii. 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 irregular notch corner fillet radius DFM check is provided in the MTK documentation, including issue classes, detection interfaces, and integration details.
