Tab-and-slot clearance per side versus kerf and burr.
No standards reference is assigned to this check. The scope described above applies.
Sheet metal · CC0-1.0
Model example
A 10 x 2 mm tab passes through a 10.1 x 2.1 mm slot of a 2 mm plate: only 0.05 mm clearance per side. Kerf and burr make such a joint jam.
Dimensions (approx.): 60 × 40 × 10 mm
PRU-107 should warn about the clearance below 0.1 mm per side and nothing else.
Finding expected
Sheet metal · CC0-1.0
Model example
The same joint with a 10.4 x 2.4 mm slot (0.2 mm per side).
Dimensions (approx.): 60 × 40 × 10 mm
PRU-107 must stay silent: the clearance is 0.2 mm per side.
No finding expected
Sheet metal · CC0-1.0
Model example
A 2 mm wide, 10 mm long tab projects from the edge of a 2 mm plate. A tab should be at least max(2 x t, 3.2 mm) = 4 mm wide.
Dimensions (approx.): 70 × 40 × 2 mm
PRU-107 should warn that the 2 mm tab is narrower than 4 mm and nothing else.
Finding expected
Sheet metal · CC0-1.0
Model example
The same plate with a 5 mm wide, 12 mm long tab.
Dimensions (approx.): 72 × 40 × 2 mm
PRU-107 must stay silent: the 5 mm tab is wide enough.
No finding expected
