Get PriceTo find approximate rpm the old machinists would follow the formula rpmcsx4d which is essentially the same as what we use today rpm sfm x 3 tool diameter, just without the division the "scs" "sfm" is the cutting speed in feet per minute, 4 is a constant, and d is the diameter.
Get PriceBall nosed cutters slow nose speedhe biggest challenge with ball nosed end mills of various kinds is slow nose speeds you get closer to the tip, the diameter on the ball gets smaller and smaller, finally going to zeros a result, the cutter must perform over a wide range of surface speeds and chip loads at different depths in the cut.
