UMC 750 Post and/or Operation Help

[Alex Kellerton]

Hi guys, 

I'm about to lose it because I don't know how to lock my B-axis for a dynamic multi-axis roughing op. I have a part that I'm programming and the owners want me to utilize 5 axis toolpaths for roughing. I made a swarf for the undercuts that posts correctly, and even a triangular mesh constant cusp toolpath for finishing the floors that posts correctly. The two that post right keep it simple and move only the B-axis. Problem is the dynamic wants to post B and C which I'm sure is fine but now its hitting my B- limits. Does anybody have any idea to possibly lock the C-axis? I figure since the swarf works then so should my dynamic. 

Sorry I'm having a difficult time wording this right but here's some pictures of the two ops that work, and the one that doesn't.

THANK YOU x1000000!

 MATERIAL IS Ti 6AL-4V.

You cannot switch that toolpath to only do 4 Axis. You might look at doing a toolpath using this to make NCI and then try to use the convert to 5 Axis to see if you can trick it to a 4 Axis output. Yes I know it sounds odd take a 5 Axis toolpath and covert it to 4 Axis, but maybe that is the way you trick the software into doing what you are needing.

Did you try moving the part so it is crooked and it uses more c axis and less b axis it might be tougher to fixture  and probe your part but if your boss is looking for a bunch of axis movement might be the way to go.
