Hello

 

I stuck with this problem. I don't have alot of experience with fusion 5-axis simultaneus opreations, but i need to find a way to cut this undercut in a spiral / constans-z way, but no matter which operation i choose, it seems like it won't go in under the overhang, even though i have seen youtube videos showing simultaneos undercutting being done. 

 

Also the videos i have seen of steep and shallow to undercutting, there was a undercutting checkbox, but this seems to have been removed??

 

I have tried with both 2mm, 3mm, 4mm none of works.

 

It's a part for an customer, so i can't share the part, but i will do my best to show the settings.

You need to select steep only, then the machine undercuts checkbox appears again.

A fine example of really bad interface.  That box should always be there, there should never be any appearing check box anywhere.  The box should be disabled, and when hovering above it, a short explanation on how to get it enabled.  That stuff is so frustrating...
