Hi All,
Need some advise on how to Rough out a 3.5" dp. pocket in a 3.5656x 5.375 x 7.125 alum..I want to use an indexable end mill 1.0"dia. @.50doc.,Then use a carbide endmill to finish the walls and floor ,need at least a 32 finish.What I wanted to know is should I plunge rough the pocket out first or just use the indexable to rough.I am using a new Haas VF-3SS Vertical mill with thru spindle coolant and programable coolant and air blast.This is a semi production(ten pcs or less).I am usin three vises,One to do pocketing drilling on first side,Second vise for the bottom side(adjacent),Third vise to do side holes.Any advise would be very helpful and grateful.
John
