Detailed Description

Describes small distance between threaded hole and edge issue found during CNC Machining drilling design analysis.

A thread edge distance issue occurs when a tapped hole is positioned too close to the edge of a part. Insufficient wall thickness around the thread reduces the strength of the connection and can cause stripping of threads during torque application or vibration during the tapping process. If threads strip or deform, additional rework such as retapping may be required, which significantly increases manufacturing time and cost. In practical cases, retap labor can add up to approximately +100% of the feature cost.

Contains threaded hole and edge that fail the following condition:

\[ \large Dist \leq Dia_h * Rt \]

\[ \begin{aligned} & \small Dist - \text{actual distance from threaded hole to edge} \\ & \small Dia_h - \text{actual threaded hole major diameter} \\ & \small Rt - \text{expected maximum distance to diameter ratio} \end{aligned} \]
