Downloaded from https://www.everyspec.com APPENDIX C MIL-STD-31000A Numerically controlled manufacturing: Sharp edges are prone to breakage. Sharp notches may promote cracking during manufacture. Recommended correction: Unless the design intent requires sharp edges, revised the edge loop to eliminate them. C.7.4.6. Inconsistent edge in loop (G-LO-IT). Definition: The direction of an edge loop in parameter space is inconsistent with its underlying boundary curve. The criterion is true if the directions are consistent. Effects of condition on CAD data quality: Design and drafting: No effect on quality. Data exchange: Unwanted self-penetration and face degeneration may occur.
Faces may not trim properly following translation. Finite element analysis: No effect on FE applications. Numerically controlled manufacturing: No effect. Recommended correction: Reverse the edge direction if necessary. C.7.5. Face criteria. C.7.5.1. Large edge face gap (G-FA-EG). Definition: The distance between any point on an edge and the closest point on the base surface exceeds the allowable maximum. 107
