Cgmp Sheet Metal Minimum Radius

Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii.

Cgmp sheet metal minimum radius.

The minimum bend radius data shown in these charts is measured to the inside of 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. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough. But for harder materials e g.

Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. When the sheet metal is bent a bend radius is required at the bend. Bend radii minimum bend sizes it is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Minimum inside bend radius for sheet metal recommended inside bend radius for sheet metal parts should be equal to material thickness.

We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. 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. It requires an inside bend radius of at least 6x the material thickness.

5052 h32 aluminum bends in about the same way as mild steel. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. 3003 h14 is extremely ductile almost like copper. Ductile material works great with small bend radii and short flange depths.

Use this document to choose values that are both manufacturable and meet your needs. 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. The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered. Avoid large sheet metal parts with small bent flanges.

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.
