Friction Drilled/Tapped Holes Modeling and Sizes

Inch Thickness Gauge Standard

Friction Drilled Tapping is not applicable for Inch Thickness Sheetmetal

Metric Thickness Gauge Standard

Friction Drilled Tapping Holes Modeling Rules

When a cylindrical flange shape element is detected, it will be identified as a friction drilled/tapped hole.

Modeling Rules	Example
The inner diameter (d) should follow the same rules as for Tapped Hole Identification described above. Model the flange height (h) and thickness (t) to be less than or equal to the Sheet Thickness.

Friction Drilled/Tapped Hole Size Selection

Friction drilled/tapped holes cannot be selected for perforated metals, shim plate materials (Cold Rolled Low Carbon Steel (for Shims) or 304 Stainless Steel (H) (for Shims)) or clear resin.
