Bend Line In Sheet Metal

Seems this is what you were looking for and other participants of this thread as well expressed their interest for the command.

Bend line in sheet metal.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. You can use a tape measure or ruler to measure the thickness of your sheet. 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. Bend line the line across the metal where the punch comes in contact with the metal and the bend begins.

In the featuremanager design tree expand drawing view to show the flat pattern feature. After bending the sheet we need to do some measurements as shown in figure 2. The following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal. Commonly used equipment include box and pan brakes brake presses and other specialized machine presses.

Preparing to bend sheet metal with a vise 1. Calculate your bend allowance. Manufacturing knowledge menu sheet metal knowledge sheet metal manufacturing and services. A new feature bend has been added to fusion 360 sheet metal workspace available with march 2019 update.

It gives user the ability to bend a sheet metal body along a sketched line. Hiding the bend lines also hides the sheet metal bend notes. 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. Determine the thickness of your sheet.

Having the right tools on hand will help this process go smoothly and quickly. 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 toggle the visibility of the bend region lines. 90 degrees bend angle.

Cells on the right will output the desired values. We will start by calculating the bend allowance. When a sheet metal part is created each bend has a defined neutral factor the neutral plane that doesn t stretch or compress when the material is bent. This defines the flat length of your part and controls the resultant dimensions.

From there we can calculate the k factor and the bend deduction. It is dependent on the material you are using and up to you to define for your manufacturing process. This page also includes a link to a on line calculator. 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.
