2D pocket machining outside pocket geometry

I'm fairly new to CAM, but I've been playing with Fusion 360 for sometime. For the life of me I cannot figure out why my tool path on my 2D pocket clearing operation is not being confined by the pocket I selected.

 

I'd appreciate any help anybody can offer.

Can you please upload your Fusion f3d file, go to :-

 

File > Export > Select f3d Format > Save to a location on your computer > Then attach to your next Post using the "Attachments" facility below.

The 2D Toolpaths are not what is known as "Model Aware" so if you have seperate bodies as you have where they are not joined together then instead of selecting the floor of what appears to be slots then the toolpath will in effect "bleed" under the edges.

What you need to do is either go back to design mode and join all bodies together or simply select the edges of the bodies as I have done as an example 🙂

Thank you so much.  I recognized that the bodies were separate, but I don't really know why.  Any tips (or links) on how I can learn to fix this?

Yes, in your Design mode you can use the "Combine" (See Icon with two blocks in Blue) facility to join any/all bodies together, select design, select a body as the "Target" and another as the "Tool" and select the "Join" option, done, you will then have one complete Solid Model. You can actually keep a body by checking the "Keep Tools" option. Anyway, play around with it for a while to get the hang of it 🙂 🙂

So, I downloaded your file and looked at what you selected and when I did the same on my model, it milled the rest of the project instead of the pocket I intended.

Sorry for all of the replies... I got it!!  Thank you for your help, your solution of combining the bodies was how I fixed it.  Thank you again @Anonymous
