I don't know which function to use

[ColeFri]

Good Morning,

Linked below is the project I am currently working on, in sketch there is a version of the solid stock and the other is the desired end result with notches removed. The issue is that I am very new to Fusion, I installed it Friday and don't really know what I'm doing yet. If someone has time and could glance at the program and give me their thoughts it would be much appreciated. I have a Tormach 1100MX which is already in the machine setup.

You're file isn't able to be shared, I'm guessing you're on a hobby account? You'll need to export the .f3d/.f3z file and share it here.

Have you spent any time on the numerous YouTube channels?

I attached the file correctly this time sorry. I have been looking at YouTube and have been unable to find a solution. I think part of my issue is that there isn't any stock below where I need to clear material which Fusion doesn't then see as pocket but I may be way off.

This is updated, I added a 1mm base, however the 2D adaptive is cutting the full rectangle, removing stock that needs to be left in place.

I had a look, and 1st thing is, 2d toolpaths are not model aware.  They do not know the volume that is left or anything like that, they rely entirely on your geometry selection within the operation.  You can achieve what you want with 2d adaptive, but you will probably have to make a sketch.  I tried without a sketch, but there are gaps in the model in places where it makes it difficult to achieve the desired selection.

So I used 3d adaptive, which is entirely aware of volumes that are left at any stage of your program.  You can turn on rest machining as needed.  In this case I turned it off because it is the 1st operation in the list, but if you had roughed out other areas you could turn this on and say "from previous operations" and it would know what was machined before.  I limited the machining to the area you were targeting by limiting the heights.  There are various ways to limit zones, but in this case heights was the easiest.

Have a look at the attached file, hope it helps a bit.

There's a trick to cutting partial contours, take a look at this ScreenCast. The secret is the ALT key and the ability to rechain the contour

Thank you both, the help is very much appreciated.
