Trouble with Wire Frame Swept 2D toolpath

[JStorer]

Trying to cut a cavity with a rad slotting cutter around a hub... Trying to use this tool path, but cannot get it to do what we need it to do. Seems to offset the tool dia. If you change tool dia to 0 it is closer to what we need. Anyone have any luck with this tool path and could shed some light it would be appreciated.

Did I miss something or did you not include the toolpath that you tried and failed with?

Thad, Its the last tool path Swept 2D the tool path that is displayed. Thanks

[Thad]

Sorry, but I don't see a swept toolpath in your file.

There is no Swept 2D toolpath in your file.

[JStorer]

I'm really sorry I posted wrong file.... It is the right file now...Thanks

Have you tried surface contour or do you not have mill 3?

I can only manage it with 3D swept (which I don't think is allowed in L1 or L2?). Also when I compare it to a quick Stock Model in Verify it looks like it removes a bit too much material in the undercut - tread carefully!

All wireframe toolpaths are included in level 1.

All wireframe toolpaths are included in level 1.

 

Unless they changed that recently, that is incorrect. I recall coons and swept 3D not being available in ML1. They're in the menu, but they can't be used.

Your right, it isn't included. 3D swept and Lofted require a level 2 licence.

Rich, looks really good verified and compared to model looks great... Can you help me understand how to pick the correct geometry?? I must be selecting something wrong it seems to want to go all over the place.. Thanks for your time

I used the Partial mode in the Chaining dialog, this may be where you are going wrong. I've attached another file that has some text to show you the order I picked the chains. I used Partial chaining for both shapes (and sync mode was set to "none"). By the way I selected the red chain first (that's the Across Contour).

 

I'm glad that your verify looked good, I think maybe I was thrown by the precision setting in my Verify which was in the middle. Looks better now I bumped the quality up
