DBC-004

Pack: G_BASELINE Severity: major

Keep turned parts stubby enough to resist deflection during cutting

Rule Card

Field Value
Pack G_BASELINE — DFM Baseline Codex
Title Keep turned parts stubby enough to resist deflection during cutting
Severity major
Check logic Hybrid
Applies to CAD part
Inputs required part_bounding_box, geometry_features
Fix template Shorten the unsupported span, increase section stiffness, or redesign the route so the feature is not a long slender turning problem.

Short Description

Long slender turned parts bend under cutting load, which hurts accuracy, finish, and safety. Support can help, but the first design move is to avoid excessive length-to-diameter ratio.

When It Applies

This rule belongs to G_BASELINE (Shared across multiple manufacturing routes) and targets CAD part.
