Downloaded from https://www.everyspec.com APPENDIX C MIL-STD-31000A Design or drafting: A quality defect only when tangency is intended. Data exchange: No harmful effects on data exchange. Finite-element analysis: No harmful effects on mesh generation or model solution. Numerically controlled manufacturing: Sharp edges should generally be avoided in manufacturing. However, when making machine parts, removal of sharp edges may be covered by a general note or specification. When tangency is intended between edges, non-tangent curves produce noticeable defects in finished products. Recommended correction: Adjust one or both entities to eliminate the unwanted condition. C.7.4.3.
Non-smooth edges (G-LO-NS). Definition: Radius of curvature changes at the common end point of two edge segments. Discontinuous curvature is a quality defect only if adjacent edge segments are required to have continuous curvature. Design or drafting: A quality defect only when curvature continuity is required. Data exchange: No harmful effects on data exchange. Finite-element analysis: No harmful effects on mesh generation or model solution. Numerically controlled manufacturing: Curvature discontinuity is visible in finished parts. No effect on machining operations. Recommended correction: Adjust one or both entities to eliminate the unwanted condition. 105
