Andy - The guys at the shop where I last worked beside used to slightly grind the flutes of a standard end mill, leaving (say) 6mm of flute length for cutting pockets.
That way, the "higher up" flutes did not re-cut swarf, and thus deflect the tool, and there was no tool rubbing on the higher up sections, either. They cut many complex shapes used in space, air, water, and underground, so they were well worth asking for advice. Maybe that would do for you? ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
