Tapered ballnose endmills are the most commonly used cutters for deep cnc carving in wood plastic and metal their tapered profiles make them much stronger than equivalent straightwall tools while providing more flute volume for efficient swarf removal in deep singlepass machining operations.
The biggest challenge with ball nosed end mills of various kinds is slow nose speed as you get closer to the tip the diameter on the ball gets smaller and smaller finally going to zero as a result the cutter must perform over a wide range of surface speeds and chip loads at different depths in the cut.
This is a particularly important value when using round insert cutters ball nose end mills and all cutters with larger corner radii as well as cutters with an entering angle smaller than 90 degrees spindle speed n the number of revolutions the milling tool makes per minute on the spindle.
