It isn't easy to tell what they are showing. Initially it looks like thread-milling with a conventional tap. If you attempt thread-milling with a conventional tap and ignore the lead then you will just mill a cylindrical face due to the lead. I can imagine that you could move the X-axis down synchronised with the tap lead, but I imagine that if you were thread-milling you would very soon run out of tap length. Later sections show cutters which are definitely thread-mills. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ 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
