Refer to the chart for values for folder as well as various press brake tooling combinations. Geometry of tooling imposes a minimum bend dimension. When designing parts for laser cutting one should not make holes smaller than the thickness of the material.

As a general recommendation 0 005 in. The inside bend radius should be equal to the thickness of the material that you re forming. A 1 degree tolerance on all bend angles. In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend.

Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. For bent sheet metal variation in the raw material thickness increases the recommended precision to 0 010 in. Bends in sheet metal are manufactured using sheet metal brakes. Now that you know your bend allowance take your protractor and draw a clear line with your marker across the point at which you will bend your sheet metal.

Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the.
