Hi @sakura.cadcam

If I am understanding you correctly, you rough the model on the left and then finish the tops of those (4) standing boss features using the "yellow" surface on the right. If you recalculate the roughing toolpath, the surface now interferes with the original model.

If I am correct, what you could to is place that "yellow" surface into a default component thickness set of ignore. PowerMill throughout the project will never use that surface in it's calculations. In the one finishing toolpath, open up component thickness within the toolpath form and set that surface to machine. That toolpath will now use that surface during calculation, but in the next toolpath it will be set back to ignore.

This article may help you understand what I am referring to......How to use the component and default thickness in PowerMill

You can always share your project and I can create an example for you.

Thanks,

If you create a toolpath, then import a surface and recalculate the toolpath, it will rough the new surface.

If you need to recalculate the toolpath, add the new surface to the component thickness of the toolpath to be recalculated.

Open component thickness > Select the surface to be ignored > Acquire new component (Surface) to a new set > Set machining mode to ignore > Apply > Accept

Now recalculate the toolpath

Dear Mr. Jonathan

Thanks so much your help, I had done with your solution.

But If Powermill Improve for auto update is better:

EX: I had align in the Thickness for Ignore by Level 1 , when the surface of Level 1 change I much to manual to go to Thickness manual update. If PowerMill automatic is better.

Thanks

Hi @sakura.cadcam

It would be nice if PowerMill recognized that the user has added new surface data that may affect present toolpaths. Perhaps in the future.

Glad to see you are all sorted out here.

What you could do is, bring the surface in before you create toolpaths and set it to your Default Thickness as ignore. then when you want to use it for a specific toolpath, add it back into the machining category. This way any toolpath that needs recalculating will still have the same settings.
