There are various pattern with different properties, for examples and explanations you can take a look at kerf bending

Kerf bending and autodesk inventor


Making kerf bending under Autodesk Inventor is not easy. We setup a process using the hatch drawing function and the metal sheet mode.


First, you have to create a new object in sheet mode.

Inventor1

Draw a rectangle and extrude it using face tool. Then, draw a second rectangle orthogonal to the first one and extrude it the same way using face tool. Last, using the bend function, join the two faces. You can specify a reasonable radius here (20mm for example).
Inventor2

Use "create flat pattern" to unfold your solid.

Inventor3

Now, create a draw file (dwg).


Inventor4

In the file, create a base view (right click in the drawing area).

Inventor5

Check that the scale is "1:1", you use the "flat pattern", and "bend extend" is checked.

Inventor6


Go to the style editor under the "Manage" tab.

Inventor7

Set bend center-line and bend extent to an unused color (yellow here)

Inventor8

Now start a sketch:
Inventor9

Toggle the Sketch Only mode and draw a rectangle over your bend area:
Inventor10

Untoggle Sketch Only mode and use the Fill/Hatch Region on your rectangle. In the popup, toggle the hatch button on top left:
Inventor11

In pattern roll down menu, select "other...". Using the tool in section below (Kerf bending simple pattern generator), create a pattern and save it on your disk. Under inventor, click on load and select the generated file, then the hatch pattern. Then "ok" and "ok" again
Inventor12

Be sure to set the angle according to the desired orientation of the pattern:

Your done! You can export in pdf and cut the black lines using your laser cut machine :-)
