http://www.zwsoft.com/forum/viewthread.php?tid=772 Hello, Hopefully someone can help out with this. I have a need to cut undercut with a lollipop cutter but can't find a "valid" operation type for 3X milling. Can anyone please help?

Our five-axis product does have support for lollipops and we're considering migrating some of this capability into 3X but it definitely won't be a 2009 enhancement. Could you please send a file and enter a PCR so that we have your needs on file? thanks, bobf bobf4fun 2009-08-24 15:10:16
