Add TiB2 coating?
Harvey Tool (and possibly others?) offers TiB2 coated tools. It's particularly good for Aluminum and Magnesieum. You can check out their coatings guide for more information: http://www.harveytool.com/cms/CoatingsChart_16.aspx
I don't know if that document has enough information to add a useful coating option to HSMAdvisor or not... but even if it didn't significantly affect the speed & feed calculation, it'd be helpful for cataloging purposes alone.
Thanks in advance!
