Copper Sheet Minimum Bend Radius

Minimum bend includes minimum closeness of cutout to bend radius cold rolled steel 14 gauge 0 075 1 91mm.

Copper sheet minimum bend radius.

The minimum inside bend radius is even larger when bending with the grain. Grain direction is formed in metal in the direction in which the sheet was rolled at the steel mill. However it is important to know that this is just a broadly applicable rule of thumb you can follow for making bends in steel. 0 064 1 63 mm.

Minimum sheet metal flange bend length 3 x sheet thickness bend radius minimum hole diameter guidelines. Minimum bend bend radius. For ordinary low carbon steel plate anti rust aluminum plate yellow copper purple copper etc the inner radius 0 2 is no problem but for some high carbon steel hard aluminum super hard aluminum the use 0 2 radius will lead to bending fracture or the outer radius crack. 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.

It s true that the harder and thicker the plate is the greater the minimum bend radius. Minimum sheet metal flange bend length is required to avoid cracks in the bending area. In this case the minimum radius equals the respective sheet thickness. Each material to be worked also has its own conversion factor.

You can check full details in this post. Radius is the minimum producible inside radius for this material and not the recommended inside radius that you see on the bend allowance chart. The minimum bending radius for this shd gc cable is approximately 12 5 inches. If copper has to be bent a factor of 1 5 must be used.

For steel the factor is 1. 0 064 1 63 mm. The die opening that the calculator recommends will achieve that. 0 064 1 63 mm.

Multiplying 2 08 inches by six we get 12 48 inches. It shall be equal to three times of sheet thickness plus bend radius. 0 064 1 63 mm. According to table 1 the minimum bend radius is found to be six times the cable s overall diameter.

The overall diameter of the cable is given as 2 08 inches in the product catalog. 0 064 1 63 mm. Your input for die opening compares the calculators answers to the results of your choice of die opening. 0 064 1 63 mm.
