Family of cutting inserts, milling cutting tool, and cutting insert

Abstract

A family of cutting inserts includes a plurality of different inserts, each having a different geometry. Each insert of the plurality of different inserts is adapted to be mounted in a common insert-receiving pocket on a toolholder of a milling cutting tool so that an outer diameter generated by the milling cutting tool is the same, regardless which insert of the plurality of inserts is mounted in the pocket.

Description

technical field [0001] The present invention relates generally to cutting inserts and in particular to cutting insert sets usable in the same tool holder. Background technique [0002] In milling operations, the use of round shaped inserts can provide a depth of cut equal to half the insert diameter, or create a radiused arc at the bottom of the workpiece. The lead angle of milling tools with round inserts depends on the depth of cut. The greater the depth of cut, the greater the chamfer. To achieve maximum material removal rates with round inserts, the traditional approach is to use large depths of machining and avoid reaching high feeds per tooth. This approach tends to generate high radial cutting forces, which are acceptable when the tool overhang is small, but which produce chattering effects when the overall length of the tool is large. [0003] For high-feed inserts, eg with four cutting edges, the maximum depth of cut is reduced due to the shape of the insert, and...
