A series that progressively increases the the size of a cut

[JonnyPot]

Hello everyone. I have a series of a flange and i want to make a cut in each flange starting at 20 and progressively increasing until it reaching 40, the number of the series is not constant, it changes in base of the height. Is there a way to do this other then manually?

 

Thanks in advance

Nothing fancy or automated comes to mind that would solve that problem without putting more work into it than it's worth.  What about cutting those flanges down from the side view with an angled line?  You could create a sketch on the "YZ Plane" (center plane), sketch an angled line across those flanges, then probably add 3 more lines to create a closed profile that you can use to extrude cut those flanges down to size.  The angle can have a couple dimensions controlling the slope.  Just a thought.

I would think you could do this by using a thicken feature to the faces of you pattern elements. You can calculate the distance for each step. So my idea would be create a named Face on you first flange. Use a rule to create or update your first thicken, then find on each element the face with the same area and use this for creating or updating the thicken feature. Also cleanup Thicken features if your number of flanges will decrease. I made a small sample, you might need to improve some thing, but the idea will work. Use the form in the model to update the height.
