2D Contour: Rest machining not working?

[FrodoLoggins]

As you can see in the below video after copying the original tool path with rest machining enabled and the disabling rest machining [on the copied toolpath] the toolpaths are exactly the same:

EDIT: Removing the Minimum Cutting Radius value of .01" allows rest machining to work but with .01" being so small that should have no effect here?

From a quick look at your file it looks like you have the same tool for both operations (T2) so that would that not be  likely give you the same toolpath maybe ??

[FrodoLoggins]

The 1/4" tool is tool 4. The .078" tool is tool 2. 

The reason why you're seeing the "same tool" is because I copied and pasted the "rest machining" operation to show that there is no difference between rest machining being enabled and disabled.

Why didn't you watch the video?

To me all I see is a second toolpath for the same Contour using a tool small enough to actually do the job anyway, so regardless of whether the "Rest" is on or not, it is just an open Contour so the new tool will just follow the selectd edge, there is not a requirement for a "Rest" function that I can see for this type of toolpath so I would not expect to see any difference anyway 🙂

Your Video is of very poor quality, may just be the Servers being slow at this time of day and also there is no Audio explaining the blurry actions on screen so I close it down as it tells me very little 😞

Just checked, the video quality is fine. If you're having playback issues you can click the little gear icon and then change the video quality:

A 1/4" end mill can not mill a corner with a 0.078" radius. So I'm using a follow up operation with a .078" diameter tool. Selecting the rest machining setting is not required, but this is a production run so I'm trying to save as much time as possible by not milling what was already milled.

I'd also like this looked at so I don't encounter this in the future where it does matter.

Please stop lying.

Hmmm, yes, looked at it again and agreed, it should work.

However it does work, I think your issue was making a copy of the first Contour with the 1/4in tool and then trying to in effect use the same Operation again, Fusion got confused I think, same here 🙂

I deleted the second (copied) Wall Operation and created a new 2D Contour and set it to "Rest Machining" from a preceding tool size of 0.25 and it seems to work as expected, I understand what you are trying to achieve by not doing the full Contour again, see the image below and attached file 🙂
