Hi MMBB,
Am I understanding correctly that you would like to know how to separate (part off) the machined block from the rest of the stock?
If so, the simplest solution is to use a contour tool path on each side to cut in from each side until only a small pedestal is left and the part can broken off of the stock.

Thanks！This is a really easy problem but I’m a new guy to use this machine.
Hey, could you please give me some screenshot or anything else to teach me how to cut in from each side. I use the contour tool path but it can’t spawn a tool path.
Hi MMBB,
The way I typically do this is to go back to the “Design” workspace and add a sketch of a box that represents the pocket or groove I want to remove to create a small pedestal. Then you can constrain your toolpath to “inside boundary” and it will only cut within your box. Typically a pocket operation or adaptive clearing is what I use. I then use a 4X circular pattern so the same cut happens on all four sides and leaves me with the square pedestal in the middle. Please see the attached images.
Thank you,

I have attached a Fusion 360 file that demonstrates the approach I mentioned above. The contour was made for one side and then patterned, that is is why it is nested under "Part Off [Circular].
Hopefully this helps but if you feel like you could use a bit more explanation I would suggest doing a quick search on Youtube for “Fusion 360 Contour Toolpath”. There are a lot of very informative videos on the subject.
Best,

Thank you! I will try this method!
Thanks a lot! I will check this file!
Linking another related thread: Cutting off part from bar stock after machining.
Also wanted to add, since I had to think through this: cleanly cutting off the part with the supplied Datron 0068630E tool is not going to work. The flute diameter is 3 mm, while the shank diameter is 3.175 mm (1/8"), so you can really only cut 9 mm into the part before the shank collides with the part. Since the part is 31.75 mm wide, you’ll be left with a 13.75 mm wide pedestal, even if you cut away some of the stock to make way for the tool.
You could cut twice to make a second pedestal and reduce the first wider pedestal to be 0.175mm high, but easiest might just be to get a tool that has a 1/8" flute.
