INDEXABLE MILLING ap max. ab Maximum cutting cedge length INDEXABLE MILLING RECOMMENDED CUTTING CONDITIONS Tool Overhang Recommended cutting conditions on this literature are chosen based on deflection, vibration and machined surface when using a CAT50 arbor. Conditions-"a" is the length from a gage line to the arbor end face, and "b" is the neck length (tool overhang from the arbor).
