Rule 01
Internal Corners
Compare geometry and machining access
Not Recommended
Round milling tools cannot directly machine an absolute sharp internal corner.
May require secondary EDM processing.
Standard Practice
Designing an internal radius allows standard milling tools to follow the corner efficiently.
Recommended: R ≥ 1 mm
