2.5D noob CAM issue (it me, not Fusion... I think)

So, I'm visiting my uncle, who has a Tormach 1100 and we are trying to make a fidget spinner for his daughter. I have designed it in Fusion 360 and have been able to do most of the CAM paths just fine but I am at a loss as to where I am going wrong for the 2.5D part and I'm hoping someone will take pity on a noob and help me out. I have build the part as one object out of .25 aluminum, which is the thickness of most of the body. Then there is a "leaf" part that is .2" thick and that is what is getting me stuck. When I try and clear the leaf bit down the .05" my tool (.25 end mill) over cuts and runs into the main body of the spinner. I have no idea how to tell it that it is running into material that is apart of the final design... there is a good chance I am using the wrong operation and or I am just missing something simple and its tripping me up. Unfortunately I am use to more simple oppositions on my CNC router so my terminology is pretty limited. I hope this plus my screen cast makes sense... you can see where it is over cutting the stock into my part. And I for the life of me have no idea how to fix the problem, let alone have the vocabulary to search for a solution here.

 

thanks in advance to anyone that tries to help!

I don't know what surfaces/contours you have selected for your pocket, but even the adaptive it seems to hit your upper section of the fidget.

 

But about the 2D pocket that mills the lower section of the model, it seems the green toolpath hits your model, that is the lead-in/lead-out toolpath, check your setting in the LEAD IN section, in LINKING tab maybe you can make it retract directly up, or leadin/lead-out in another section of your fidget.

 

I think if you export your model and attach it other users could help you, it will be much easier to find a possible solution.

Here is the file if anyone would be kind enough to point me in the right direction. 

 

Thank you!

This one might seem a little weird, but you'll want to select what you don't want to cut and then define your stock areas:

Also a note: if you right-click on the toolpath and open the Compare & Edit dialogue, look for the option "Order by Area" and set it to Yes. This will keep the tool in the same area and avoid jumping around as much. The above toolpath screenshot is set this way. I would also suggest tightening the tolerance to at least .001" instead of the default. My default is set to .0005".

 

I haven't touched any other operations except for 2D Adaptive5.
