Bend line sheet metal.

Cells on the right will output the desired values. Bending is a manufacturing process that produces a v shape u shape or channel shape along a straight axis in ductile materials most commonly sheet metal. Bending is one of the most common sheet metal fabrication operations. Bend line the line across the metal where the punch comes in contact with the metal and the bend begins.

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. How to bend sheet metal without a brake. Some items to note about a sketched bend feature. You only have to insert interior angle flange lengths k factor inside radius and material thickness.

Bump bending also known as step bending the process for forming a large radius with conventional tooling by performing a series bends in close proximity. Commonly used equipment include box and pan brakes brake presses and other specialized machine presses. How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools. This page also includes a link to a on line calculator.

Most sheet metal materials will conform to the calculations. This is done through the application of force on a workpiece. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Then use your bend allowance to draw your second bend line the intervening distance between your bend lines bend radius.

This lets you dimension the bend line to other geometry. Sheet metal manufacturing and services the following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal. Your bend lines are stored in the same location as above but there are 2 other sheet metal features that can interfere if you change the default way those are displayed if you do not change anything with in them then you should have nothing to worry about. To think about bending a sheet of metal that has appreciable thickness focus on an imaginary central sheet the so called neutral line or neutral axis within the thickness.
