I keep trying and failing to come up with a roughing strategy for the backside of a telecaster.
Since this is the fist of 2 setups, and I will need to flip the stock, I am only trying to remove the material in the "belly cut" area of the guitar and the perimeter fillet while leaving the bulk of the remaining stock around it for alignment in setup #2.
No matter what I do, I end up with collisions.
You almost had it,
the reason its showing collisions is you didn't have Rest machining turned on
So If you turn that on it will try and machine all the Stock away but to solve that problem just set the machining boundary to Silhouette with tool center on boundary
Now it helix into the material nicely and only machines where you want
Well, had a look at your file and like Andrew @a.laasW8M6T I was not able to get the outer fillet to be done with the Adaptive or the Parallel without any collisions.
So, I did an extra couple of Operations still using the same Ball Nose tool, first I did a "Relief" groove around the outer shape so there was material removed for the next Operation, I chose the "Blend" to do the Outer Fillet, ended up with all the toolpaths using the same tool, so no tool change involved. Probably not the best method but it does seem to work reasonably well, anyway, file attached for you, afraid that`s all I have for you on this 🙂 🙂 🙂
