Advent "Special" Thread Mill

Smith & Nephew is a proprietary medical implant parts maker in Tennessee.  With a specialized thread and a specialized fastner with a triple lead thread form and a 60 Degree included angle, you just don't see these every day.  Smith & Nephew was familiar with a very high cycle time for each thread form - not to mention very poor tool life.  Advent quoted the production of the tools, the associated engineering and test runs in house.  We found that we were wrong about cycle time - it was lower than advertised (under 10 seconds!).  Tool life was substantial in this exotic stainless steel part as well.

The trick?  Having the correct form on the mill and using an innovative programming technique to generate the triple lead in one pass by using pitch and feeds together to "nail" the form.

No pictures!  This is classified!  But imagine the correct form on a mill combined with a program from Advent and you'll get the idea...
