Bend line sheet metal.

This page also includes a link to a on line calculator. Bending is one of the most common sheet metal fabrication operations. Choose a bend radius that matches your minimum bend. 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.

But for harder materials e g. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Some items to note about a sketched bend feature. With this free online tool we quickly get the sheet metal bend deduction and therefore the sheet metal blank initial flat length from the finished part measurements.

Determine your minimum bend by measuring the distance from your closest feature i e. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material. This lets you dimension the bend line to other geometry. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough.

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. Mark your bend lines. Then use your bend allowance to draw your second bend line the intervening distance between your bend lines bend radius. Bend line the line across the metal where the punch comes in contact with the metal and the bend begins.

A cutout or the edge of your flange to your bend. 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. Recommended inside bend radius for sheet metal parts should be equal to material thickness. You can add bend lines to a flat face of a sheet metal part with a sketched bend feature.

Only lines are allowed in the sketch. This is done through the application of force on a workpiece. Commonly used equipment include box and pan brakes brake presses and other specialized machine presses. 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.

Most sheet metal materials will conform to the calculations.
