Cgmp Sheet Metal Minimum Radius

The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered.

Cgmp sheet metal minimum radius.

But for harder materials e g. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. Minimum inside bend radius for sheet metal recommended inside bend radius for sheet metal parts should be equal to material thickness.

3003 h14 is extremely ductile almost like copper. Ductile material works great with small bend radii and short flange depths. The minimum fillet radius between the flange and the wall of the tensile member should be greater than 2 times the thickness of the plate ie r2 2t. When the sheet metal is bent a bend radius is required at the bend.

In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm 0 03 inch whichever is larger. Avoid large sheet metal parts with small bent flanges. Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii. The minimum bend radius data shown in these charts is measured to the inside of the bend.

So if the metal plate is 75 thick you would multiply 4 x 75 3 so your minimum inside bend radius would be roughly 3 times the thickness of the material in this case or 2 25. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough. It requires an inside bend radius of at least 6x the material thickness. However it is important to know that this is just a broadly applicable rule of thumb you can follow for making bends in steel.

We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal. In order to make the stretching smoother generally take r2 5t the maximum fillet radius should be less.

Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured.
