Please help, trouble when changing tool orientation on lathe

Trying to process a face groove on part. I have it designed to rough with a groove tool, then finish with 2 different angled 35 degree tools one for the bottom one for top. Was getting wildly wrong numbers in my code at machine. The only way the numbers look anything close to right is when I lied to the tool and said it has zero tool nose radius and try to turn on cutter compensation. I want to use 1/16" (.0156) TNR tools. Any help would be appreciated.

@tonyFTPQQ can you attach the file with the tool nose radius not set to 0 to show the issue? Without looking at your file, i suggest try playing around with the "compensation" parameter in the setup tab in the tool library to make sure you're using the right tool compensation point.

Yes new file is attached. I changed back the tnr to match reality. I have tried to post code with different compensation types selected and the numbers given were surely closer,  but never looked good to us. In fact when leaving the compensation type as tip tangent as we always do, it will wreck into the part. Also no matter the selection the toolpath looks perfect in simulation mode, numbers come out wildly different.

@tonyFTPQQ yeah, unfortunately there is a known issue with the tip tangent compensation type for an inclined neutral tool. We have a ticket for it but in the meantime, for this particular tool a workaround would be to use tip center compensation and apply cutter compensation at the control.

Do you have a Milturn Machine with B-axis or are you just putting in the tools on an angle in a normal lathe?

The tools are angled on a standard 2 axis doosan lathe.

I take it this issue has not been resolved yet? I have the same issue with tip tangent not compensating correctly for a 45 degree angled od groove tool for a grind undercut.

No, it's not yet been fixed in the commercial version of Fusion. That said, we've been actively working on exactly this issue, so stay tuned for a future update* that should see this resolved

 

*Most likely it's not going to be in the exact next update, but it's not years away
