Why my model doesn't work properly in practice?

[firanman]

Hello everybody,

I've designed a flat-dog-bone-shaped specimen in Fusion 360 to generate a G-code for the CNC mill. when I run the simulation both on Fusion360 and on my CNC machine everything looks fine but when I run the real simulation it gives me the following specimen:

what I designed is as follows:

So as you see, 2 of 4 edges have not been milled properly. I was wondering to ask if anyone can help me solve this problem. I guess there is a tool compensation parameter that I missed and I don't know how to account for that. I have attached my .f3d file as well. I'd really appreciate your advice.

Hello Mark,

Yesterday, I tried this last model that you kindly created. It worked! and I really appreciate your help! 

Just, there are some errors in the edges and the cut is not symmetric. Do you have any idea that how can I address that? 

Kind regards,
