ABSTRACT:
An improved cutter disk for machining rotating workpieces, and in particular an improvement in such cutters useful in monotonic-type cutters in which the tool inserts carried on the disk are mounted in such a manner as to present the inserts to the workpiece at a radical lead angle, optimally on the order of 60 degrees. The tool inserts are preferably carried on both sides of a V-shaped edge on the cutter disk. Chip gullets are formed in the disk parallel to the tool inserts and are angled with respect to the plane of the disk. This optimizes the space for chip gullets and allows either a doubling of the feed rate for a given chip thickness and insert density, or a reduction in chip thickness by 50% for a given feed rate. The invention also results in the optimal use of space for the chosen insert density, especially on narrow cutters, and permits an improvement in the pocket strength and insert strength, as well as improving tool life.
