Title: General machining question
Post by: at6c on August 22, 2009, 09:38:01 AM

When I cut a pocket on my mill I usually use a center cutting 4 flute mill.  At the bottom of the cut normal a small dish forms on the end of the cutter, because the ends of the flutes are tappered inward.  This is usually not an issue except when the same tool is used on the next operation and the disk sticks to the end of the mill.  The next plunge cut can stall until the disk is cut through, some times this can cause a problem.  Besides stopping the mill and knocking the disk off between cuts does anybody have any suggestion as to how they handle this problem.
Thanks,
George

"Ramp" feed the plunge cuts, that should eliminate the disc.
