In this article i explain how to avoid hole distortion in sheet metal parts.
Relief hole sheet metal.
Click corner relief sheet metal toolbar or insert sheet metal corner relief.
Bend relief and collars near pierced areas strengthen sheet metal parts.
As per sheet metal design thumb rules the depth of bend relief should be greater than or equal to the inside bend radius of the bend and the width of the bend relief should be the same as the sheet metal thickness or more.
Grain structure in the metal sheet is critical for avoiding cracks in sheet metal parts with lugs or tabs that are cut on.
For example if you make a partial flange as above using all the defaults the software makes relief cuts at the end of the bends as shown to the right.
To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
While placing the holes in your drawing please keep in mind that you should not make.
When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to rip and tear.
Under corners click collect all corners to list all corners in the sheet metal body.
Bends in sheet metal are manufactured using sheet metal brakes.
You can add a corner relief to a single sheet metal body.
Sweet relief how to avoid hole distortion in sheet metal parts sheet metal fabrication is an excellent method of making mechanical parts especially support brackets.
If no relief distance is called out on the print and you are using a large bend radius with this type of notch then to be safe use a minimum distance of the material the bend radius.
The edge of a hole is the radius of the curl plus the material thickness.
Sheet metal parts may have sharp corners but designing a fillet of the material s thickness will make parts more cost effective.
Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word.
Minimum hole size for sheet metal.
In the corner relief propertymanager under scope select the sheet metal body to which to apply the corner relief.
In low carbon steel sheet metal the minimum radius of a bend should be one.
In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
They tend to be cheap light strong and easy to pack and ship.
Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.
When designing parts for laser cutting one should not make holes smaller than the thickness of the material.
A 1 degree tolerance on all bend angles.
