Bend Radius Copper Sheet

We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

Bend radius copper sheet.

What is the minimum radius. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material. If the punch nose radius. Recommended inside bend radius for sheet metal parts should be equal to material thickness.

For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough. If copper has to be bent a factor of 1 5 must be used. Each and every bend in a piece of sheet metal has a certain minimum internal radius that needs to be taken into account when planning the design of a sheet metal form.

If your bend radius needs to be adjusted a member of engineering design services team will contact you before your design is manufactured. We want to know the final length of the detail. The minimum bend radius data shown in these charts is measured to the inside of the bend. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm.

It is the smallest inside bend radius that you can place in a piece of material before the tensile forces on the outside of the bend begin to tear the grains in the material apart. To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart. The problem with bending too tightly. If a piece of material is bent too tightly problems can occur.

The most common problem with bending a piece of sheet metal too tightly is. The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius. It is normally expressed in terms of multiples of the material thickness e g. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance. In this case the minimum radius equals the respective sheet thickness. For steel the factor is 1.

First we must start with the k factor. But for harder materials e g.
