Steep and shallow decides not to mill some of a wall

[FrodoLoggins]

Mills the left and right side, just not the rear near the hole for some reason:

Hi @FrodoLoggins, I'll take a look at your project in a bit. Meanwhile, have you tried having a positive value as the additional offset? A negative value will offset the boundary inwards so I don't think it'd be beneficial in your case. Also, try to un-tick Contact Point Boundary. If you tick it, Fusion will try avid rolling over corners. 

I'd also select the hole as a part of the machining boundary, or you risk machining the inside surface too (unless you want to).

Let me know if this helps.

Cheers

I couldnt even get it to run without crashing because of all of the collisions, but it looks like that is as far as it goes because that fillet is machined from the side of the ball mill and the lines are the tools centerpoint. That is why it stops short on the upslope portion, but goes over the downslope portion.

Hmm, I could but unchecking CPB would not allow the ball mill to go deep enough leaving extra stock:

The fillet is not only a bit larger than the radius of the ball mill, it's the same radius as the other fillets that DO get machined.

@paolo.bastianelli any updates?

Hi @FrodoLoggins ,

First of all, this is the same model as the one you sent where you found the Steep & Shallow bug (that I reported and is being looked at by development), so we already know that the boundary in that region is a bit "faulty" and will create a jagged toolpath.

However, I changed the offset to 0, added a boundary chain for the internal circle and de-activated Touch/Avoid. I got the result below, that machines the steeper section with the side of the tool. There'd be little point in more passes being generated, that's why it stops there.

Cheers
