Bend Line In Sheet Metal

Bend line the line across the metal where the punch comes in contact with the metal and the bend begins.

Bend line in sheet metal.

We will start by calculating the bend allowance. Calculate your bend allowance. Commonly used equipment include box and pan brakes brake presses and other specialized machine presses. 90 degrees bend angle.

The following illustration shows the equation calculation for determining the bend line to mold allowance when forming sheet metal. From there we can calculate the k factor and the bend deduction. Determine the thickness of your sheet. A new feature bend has been added to fusion 360 sheet metal workspace available with march 2019 update.

It is dependent on the material you are using and up to you to define for your manufacturing process. Manufacturing knowledge menu sheet metal knowledge sheet metal manufacturing and services. Cells on the right will output the desired values. Preparing to bend sheet metal with a vise 1.

You only have to insert interior angle flange lengths k factor inside radius and material thickness. 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. It gives user the ability to bend a sheet metal body along a sketched line. Seems this is what you were looking for and other participants of this thread as well expressed their interest for the command.

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. Figure 2 illustrates the sheet that is bent with the bend angle of 90 degrees. 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. To toggle the visibility of the bend region lines.

Hiding the bend lines also hides the sheet metal bend notes. After bending the sheet we need to do some measurements as shown in figure 2. This page also includes a link to a on line calculator. Expand the flat pattern feature right click bend lines and selectshow or hide.

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. 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. Most sheet metal materials will conform to the calculations. This defines the flat length of your part and controls the resultant dimensions.
